The 27-year-old Greene is one of the younger coaches on an MLB staff. This is his first big league coaching work. The Jays noted that he spent the ’24 season working as a senior pitching research specialist. Greene, a Pennsylvania native, pitched collegiately in Canada at Montreal’s McGill University. He has worked for the Jays for four seasons.

Greene joins newly-hired bullpen coach Graham Johnson as assistants to pitching coach Pete Walker. The Jays also shook up the hitting side, bringing in David Popkins to work as lead hitting instructor and tabbing Lou Iannotti as an assistant. The rest of John Schneider’s staff — all of whom are returnees from last season — is as follows: associate manager DeMarlo Hale, bench coach Don Mattingly, first base coach Mark Budzinski, third base coach Carlos Febles, assistant hitting coach Hunter Mense, and mental performance coach John Lannan.

Some more from around baseball…

• Left-hander Ryan Feierabend signed with the Uni-President Lions of the Chinese Professional Baseball League during the offseason, so Feierabend his fellow CPBL peers have gotten their season underway in Taiwan while the rest of the baseball world is still on pause, The Toronto Star’s Gregor Chisholm writes.  Since Taiwan quickly enacted measures against COVID-19, the outbreak has been severely limited on the island, thus allowing for businesses, schools, and other larger public gatherings to continue to operate, albeit under safety restrictions.  CPBL games, for instance, are being played without fans in attendance.  Given how matters seem to be somewhat under control in Taiwan, Feierabend said he “would feel more comfortable” if his wife and children were in Taiwan rather than in the United States, both for safety reasons and simply so the family could be together.  “It’s a sacrifice being away…Having to deal with that while the pandemic is going on, it’s definitely stressful,” Feierabend said, praising his wife Sarah for being “the rock of our family.”
• Arizona State’s Spencer Torkelson would be the first pick of this year’s amateur draft if MLB.com’s Jim Callis held the reins in the Tigers’ front office.  (Detroit has the first overall selection.)  Callis is a fan of Torkelson’s power potential, calling him “one of the biggest impact college bats in recent years” and saying he might deliver seasons in the range of 35 homers and a .280 average on a regular basis in the majors.  Vanderbilt outfielder/third baseman Austin Martin is a close second for Callis, and unsurprisingly, Torkelson and Martin also occupy the top two spots on MLB Pipeline’s list of the top 150 draft prospects.
• The Blue Jays have made mental performance a major aspect of their player development system at both the Major League and minor league levels, with eight-year MLB veteran John Lannan was hired as the newest member of the six-person mental performance department this past January.  As The Athletic’s John Lott (subscription required) writes, Lannan went back to school to study sports psychology after retiring in August 2017, and realized the subject matter was instantly relatable to the modern player.  “Once I was going into all these deep dives into sports psychology, it just brought to mind a lot of situations throughout my career, where it started to make sense why I might have felt the way I felt and what I could have probably done about it if I’d known more about the subject,” Lannan said.  Lott outlines the Jays front office’s philosophy about the benefits of mental performance, and how the department’s role has now evolved with players stuck at home waiting out the pandemic.

• In a surprise move, lefty John Lannan is heading back to the Nationals on a minors pact., Baseball America’s Matt Eddy reports in his latest compilation of moves from around the league. Now 32, Lannan provided the Nats with 783 2/3 innings of 4.01 ERA ball from 2007 through 2012, but didn’t exactly leave the organization on the best of terms. He appeared briefly in each of the next two seasons, and has toiled in the upper minors since. With few apparent opportunities for Lannan to regain his prior standing, it seems there’ll be some interesting changes afoot. Upon his return to the Nats organization, he’ll be working to re-make himself into a submariner relief pitcher, according to Jorge Castillo of the Washington Post (via Twitter)
• Righty Matt Buschmann will join the Blue Jays on a minor-league deal, as Eddy further reports. The 33-year-old debuted in the majors last year with the D-Backs, though he received only three outings. He spent the bulk of the year at Triple-A, throwing 142 innings of 5.26 ERA ball with 5.8 K/9 and 3.4 BB/9.
• The White Sox have added a pair of players on minors deals, Eddy adds, with righty Jake Dunning and utilityman Tyler Ladendorf joining the mix. The 28-year-old Dunning had spent his entire career with the Giants organization. He hasn’t been up to the majors since 2014, and pitched to a 4.85 ERA with 6.5 K/9 and 4.4 BB/9 at Triple-A last year. Ladendorf, who tuns 29 today, received brief time in the majors in each of the last two seasons. The former second-round pick offers plenty of defensive versatility, but hasn’t shown much bat in the upper minors. He owns a lifetime .261/.327/.349 slash at Triple-A.
• The Nationals announced that catcher Spencer Kieboom has been assigned to Triple-A after clearing waivers. He had recently been designated for assignment to clear 40-man roster space. Kieboom will remain in camp as a non-roster player, though it’s all but certain he’ll head to the minors to open the year. The 25-year-old actually hasn’t yet played at Triple-A despite a very brief appearance in the majors last year. Kieboom hit .230/.324/.314 in his 359 plate appearances at the Double-A level in 2016.

Signing either Kennedy or Gallardo would, of course, require Kansas City to part with its top draft choice. While that’s not as painful as it would be for most teams, as the Royals won’t pick until the end of the first round, it’s obviously necessary for the team to take account of that sacrifice.

The Royals were said to have interest in free agent Wei-Yin Chen, but he just agreed to terms with the Marlins. If nothing else, though, that pursuit showed the seriousness of the Royals’ efforts as well as its willingness to punt a pick. Chen’s signing also showed that there’s still hope that the other top remaining free agents can match the lofty contract expectations that led them to decline qualifying offers.

As things stand, K.C. will run out a staff fronted by Edinson Volquez and Yordano Ventura. The three leading candidates for the remaining slots are the recently-re-signed Chris Young along with Danny Duffy and Kris Medlen, either of whom could also function as swingmen. There’s some minor league depth, including pitchers like John Lannan, Chien-Ming Wang, and Brian Flynn, but it isn’t hard to see why the Royals would want to add another option.

• The Reds have signed right-handed reliever Jose Cisnero, tweets Chris Cotillo of SB Nation. Cisnero is entering his age 26 season and has a 4.66 ERA, 8.57 K/9, and 4.84 BB/9 in 48 and one-third career innings – all with the Astros. Cisnero was outrighted by Houston earlier in the month and has inked a minor league deal with Cincinnati.
• In the same tweet, Cotillo also reports four other minor league signings. The Mariners re-signed Burt Reynolds, the White Sox inked left-handed reliever Joe Savery, and the Rockies signed right-hander Brett Marshall and left-hander Aaron Laffey. Of the four, Laffey comes with the most major league experience – 487 innings of 4.45 ERA ball. The soft-tossing lefty’s last extended stint in the majors was in 2012. Marshall had a 12 inning cup of tea with the Yankees in 2013 but struggled to a 6.53 ERA with the Reds Triple-A affiliate this season. Savery, a former first round pick, has seen spot work in parts of four seasons. The Phillies tried to use him as a lefty specialist, but he’s actually posted reverse platoon splits.
• The Rockies have also signed pitchers Justin Miller, Jose Ortega, and John Lannan, tweets Matt Eddy of Baseball America. Right-handers Miller and Ortega saw minimal work for the Tigers, where they have posted uninspiring numbers. Lannan is a major league veteran of eight seasons, although he hasn’t seen a full season of action since 2011. He has a 4.18 ERA, 4.70 K/9, and 3.39 BB/9 in 862 career innings.
• The Dodgers have signed infielder Buck Britton to a minor league deal, Dan Connolly of the Baltimore Sun tweets. Britton, the brother of Orioles reliever Zach, had spent the previous seven years in Baltimore’s system. Last season, the 28-year-old hit .289/.345/.453 in 505 plate appearances split between Double-A Bowie and Triple-A Norfolk, primarily playing second base and third base.
• The Giants have signed infielder Carlos Triunfel and lefty Braulio Lara to minor-league deals, Baseball America’s Matt Eddy tweets. Triunfel hit just .223/.256/.330 for hitter-friendly Triple-A Albuquerque in 2014, mostly playing the two middle infield positions. The Dodgers outrighted him in September. The 25-year-old Lara posted a 5.77 ERA with 8.9 K/9 and 4.8 BB/9 in 57 2/3 innings of relief in a 2014 season spent in the upper minors of the Rays’ system.

WEDNESDAY: The Mets have outrighted left-hander John Lannan to Triple-A Las Vegas and purchased the contract of right-hander Daisuke Matsuzaka, tweets MLB.com's Anthony DiComo. Lannan will have the option to reject the outright assignment in favor of free agency. ESPN New York's Adam Rubin tweets that Matsuzaka will work out of the bullpen for now.

Lannan, 29, appeared in five games for the Mets this season, allowing seven earned runs on seven hits and a pair of walks in four innings of work. Of those seven hits, three cleared the fence for a home run. The veteran has never pitched outside of the NL East, but he's donned the uniform of three teams in that division: the Mets, the Phillies and the Nationals. After posting a 4.01 ERA in 783 2/3 innings with the Nationals from 2007-12, Lannan has struggled. With Philadelphia and New York, he's managed a combined 5.86 ERA with a 40-to-29 K:BB ratio in 78 1/3 frames.

Matsuzaka spent some time with the Mets in 2013 after signing a minor league deal midway through the season. He started slow but fared well down the stretch, yielding just four earned runs over his final 26 1/3 innings while striking out 21 and walking nine. Matsuzaka then signed another minor league deal with the Mets this winter. He's allowed two runs and punched out 12 hitters in 12 Triple-A innings this season. Matsuzaka's minor league deal calls for a $1.5MM base salary in the Major Leagues, and he also received a $100K retention bonus at the end of Spring Training after he did not make the Opening Day roster.

• As expected, the Mets have added lefty John Lannan to the 40-man roster, Newsday's Marc Carig tweets. The longtime starter is expected to work out of the pen for the first time in his career after serving exclusively as a starter for 148 games between 2007-13.
• Jason Bartlett will make the Twins as a reserve infielder and center field option, tweets Phil Miller of the Minneapolis Star Tribune. The 34-year-old had previously agreed to bump back his opt-out date. Though he has played exactly one MLB game at a position other than shortstop (a single 2004 appearance at second), Bartlett will apparently see some time in the outfield. He finds himself in position to break camp after taking just 98 professional plate appearances over the last two seasons.
• 25-year-old outfielder Ryan Kalish will make the Cubs Opening Day roster and be added to its 40-man, tweets Jesse Rogers of ESPNChicago.com. It was reported yesterday that the same was true of utilityman Emilio Bonifacio, per Mark Gonzales of the Chicago Tribune (via Twitter). Chicago has two open roster slots, so no corresponding move would appear to be necessary. As Rogers notes, third baseman Mike Olt will also be on the active roster to start the year.

Elsewhere in the National League:

• With the possibility Niese may open the season on the disabled list, Jenrry Mejia could join Daisuke Matsuzaka in the Mets' rotation with John Lannan earning a relief role, according to Rubin.
• The Diamondbacks are another team scrambling to fill a void in their starting rotation in the wake of the news from earlier today Patrick Corbin could be facing Tommy John surgery. GM Kevin Towers, however, plans to use in-house options like Randall Delgado, Archie Bradley, and Josh Collmenter rather than seek a trade immediately, tweets Jack Magruder of FOXSportsArizona.com.
• Noah Syndergaard, who remains in the Mets' Major League Spring Training camp, was the key component in last offseason's R.A. Dickey trade, writes Matt Ehalt of the Record. "I think eventually it got to the point where we needed Syndergaard," said J.P. Ricciardi, the Mets' special assistant to the GM. "I think in order to finish it off, we needed a younger, higher prospect to make us say, 'OK, it's worth trading a Cy Young Award winner.'"
• Pirates GM Neal Huntington says the team's bullpen depth is "a chance to move a guy that can go help someone else to add a piece," tweets the Pittsburgh Tribune-Review's Travis Sawchik. Huntington also gave a near-guarantee Edinson Volquez will be in the Pirates' starting rotation, Sawchik tweets.
• Troy E. Renck of the Denver Post contradicts a story from this morning the Rockies are in the market for right-handed bullpen help. A source tells Renck the club prefers to give Chad Bettis or Chris Martin a chance before pursuing a trade.
• Being forced to rush their young pitching prospects to the Majors has come back to haunt the Marlins, as Jacob Turner and Brad Hand (22 and 23, respectively) are now out of options, opines MLB.com's Joe Frisaro.
• The Dodgers have selected the contract of Justin Turner and will bring Chone Figgins to Australia, reports Dylan Herndandez of the Los Angeles Times (Twitter links). MLBTR's Tim Dierkes broke the news in February of Turner agreeing to a minor league contract with the Dodgers and now the 29-year-old will make $1MM as a reserve infielder. Figgins, who signed a minor league deal in January and is trying to make the squad as an utilityman, will be one of 30 players the Dodgers are taking on the trip (only 25 will be active on game day).

• Mets manager Terry Collins told reporters, including Newsday's Marc Carig (Twitter link) that Daisuke Matsuzaka and John Lannan are the favorites to win the fifth spot in his rotation. MLB.com's Marty Noble writes that Collins is still considering Jenrry Mejia, though the youngster is more likely to be used in a long relief role out of Spring Training. Noble writes that the Mets feel that role would allow Mejia to continue to build arm strength and can also serve as a developmental tool.
• ESPNNewYork.com's Adam Rubin writes that Mike Piazza is in Mets camp to serve as a special instructor but says he's not looking to get into coaching on a full-time basis anytime soon. Piazza says he has a seven-month old son, so his focus appears to be on his family. Travis d'Arnaud calls Piazza's tutelage "a dream," as the Long Beach, Calif. native grew up idolizing Piazza as a Dodgers fan.
• New Phillies hurler A.J. Burnett made his Spring Training debut over the weekend, and it came against his former club, the Pirates, writes Rob Biertempfel of the Pittsburgh Tribune-Review. Pirates manager Clint Hurdle and Burnett himself both told Biertempfel that there was nothing weird about Burnett pitching against the Bucs instead of for them, and neither hinted at any ill will. Hurdle simply called the change "part of the game," and Burnett offered nothing but respect for his former club.
• ESPN's Jayson Stark writes that although the Braves lost Tim Hudson to the Giants via free agency, talk that the club lacks an ace is overblown, as Kris Medlen has developed into that type of pitcher for the team. Assistant GM John Coppolella said of Medlen: "Look, the fact that he’s not 6 feet tall and that fact that he doesn't throw 95 [mph] makes it seem like he’s not a power guy, but he’s very good with what he does. … He’s a huge part of our staff. And we hope he will be for a long time."

• Blue Jays GM Alex Anthopoulos hopes his club can benefit from the qualifying offer system given its array of draft picks, Ben Nicholson-Smith of Sportsnet.ca reports. With two protected first rounders, the Jays would stand to lose only a second-round choice by signing a free agent who comes burdened with draft pick compensation. "It's significant," said Anthopoulos. "I think if we had to give up a first round pick, it would changes thngs in a significant manner. I think that's where the draft pick compensation component is impacting some of these clubs." Though he said that "there's still value with the second round pick … and you still build that into an offer," Anthopoulos explained that "it's not close to the value of round one."
• Mets GM Sandy Alderson says he is "still looking for more players," reports ESPNNewYork.com's Adam Rubin, but emphasized that he likes the club as currently constituted. "I think we've spent the fifth-most of any team in Major League Baseball on free agents this offseason," said Alderson. "And we might do something else before Spring Training starts."
• Meanwhile, two New York starting pitching options — the recently signed John Lannan and Daisuke Matsuzaka — have opt-out provisions in their contracts, Rubin reports. Lannan has a June 14 date in his deal, while Matsuzaka has the standard Type XX(B) contract (for minor league free agents with six-plus years of service), which includes a June 1 opt-out. 
• The Phillies should act on their reported interest in free agent starter A.J. Burnett, opines Todd Zolecki of MLB.com. With Roberto Hernandez a puzzling addition and international signee Miguel Alfredo Gonzalez still a "huge wild card," in Zolecki's view, the Phils should go hard for Burnett unless the club really does not believe it is a likely contender.
• We heard earlier today that the Orioles and Rays are also possible contender's for Burnett's services.
• The Orioles are interested in bringing back Jason Hammel, but probably are not his likely landing spot since they would not guarantee him a starting role, reports Dan Connolly of the Baltimore Sun. Baltimore executive VP Dan Duquette also acknowledged that "it would be nice" if the club could announce a significant addition at the team's fan event on Saturday, but of course emphasized that the event would not sway the decisionmaking.
• Baltimore announced a pair of international signings: 17-year-old Mexican Carlos Diaz and 16-year-old Dominican Jomar Reyes. As MLB.com's Brittany Ghiroli reports (Twitter links), both teenagers are expected to start out in the Gulf Coast League. Duquette said that multiple other clubs were involved, and labeled Diaz and Reyes as "potential everyday major league players that can hit in the middle of the lineup." The indicated said that the two received "substantial" bonuses, Connolly reports on Twitter.

SATURDAY: The Mets have signed lefty starting pitcher John Lannan to a minor-league deal with a spring training invitation, according to a team release. Lannan, who is represented by CAA Sports. He'll provide depth for the Mets' rotation.

Lannan posted a 5.33 ERA with 4.6 K/9 and 3.3 BB/9 in 74 1/3 innings for the Phillies in 2013. He would have been eligible for arbitration, but the Phillies outrighted him in October. The longtime Nationals pitcher has a 4.12 ERA with 4.7 K/9 and 3.4 BB/9 in 858 lifetime innings.

THURSDAY, 6:59pm: The Phillies have outrighted pitcher John Lannan, according to the team. Lannan pitched 74 1/3 innings for the Phils in 2013, posting a 5.33 ERA with 4.6 K/9 and 3.3 BB/9. A knee injury ended his season in August.

Lannan agreed to a one-year, $2.5MM deal with the Phillies after being non-tendered by the Nationals last offseason. He would have been eligible for arbitration again this offseason as a fourth-year Super Two. For his career, Lannan has a 4.12 ERA with 4.7 K/9 and 3.4 BB/9, but he still ended up pitching much of the 2012 season in the minors while still in the Nationals organization.

• Ruiz would like to return to Philadelphia, writes Salisbury in a separate piece, and the organization has taken note of his recent surge at the plate, with GM Ruben Amaro Jr. stating that Ruiz looks far more relaxed. Pitching coach Rich Dubee, who knows Ruiz quite well, feels that Ruiz is best limited to 100 games behind the plate at this point in his career, however.
• Ben Lindbergh of Baseball Prospectus writes that Darin Ruf is exceeding expectations of scouts and talent evaluators with his production at the big league level so far. Lindbergh's piece includes an excellent interview with Ruf, conducted last week, in which Ruf discusses what scouts thought of him, his limitations on the field and his journey from senior sign/20th-round pick to a potential long-term asset for the Phillies. "I’m probably a bad person to ask prospect-type questions because, I don’t know, I never was one," Ruf candidly replied at one point in the interview.
• Roy Halladay and Kyle Kendrick will force the Phils to make tough decisions this offseason, writes MLB.com's Todd Zolecki. The Phillies have four more starts to evaluate Halladay's progress from shoulder surgery, but as Amaro noted to Zolecki, it's possible that Doc won't be at full strength until next spring. Amaro and his staff will have to decide whether or not to bring Halladay back on an incentive-laden deal or seek a more certain commodity.
• Likewise, the decision on whether or not to tender Kendrick a contract that could approach $8MM via arbitration is no easy decision. Kendrick has never been on the disabled list, Zolecki noted in a different piece, a trait that would make him desirable to other teams should the Phillies non-tender him and try to sign him for less money. Dubee agreed: "If something doesn't happen here, I'm sure there's going to be plenty of seekers. He's durable. He hasn't missed a start all year. Those guys are highly sought."
• Zolecki also adds that left-hander John Lannan is likely to be non-tendered by the Phils this offseason following surgery on his left knee.

• Starter Roy Halladay says that, while he respects Manuel, a change was needed. As Matt Gelb of the Philadelphia Inquirer reports, Halladay thinks that interim manager Ryne Sandberg will "bring back a little more of the Philly baseball style than we've had the last couple of years." According to the veteran righty, "We haven't had that whole team effort, that whole team hustle. … Guys being at places on time; being on the field on time; taking ground balls; taking extra BP. All of those little things that nobody thinks makes a difference."
• Indeed, Sandberg has already announced his presence by calling out veteran shortstop Jimmy Rollins, Gelb reports. "Is he stubborn or [has he] created habits that are hard to change?" queried Sandberg. "I've seen him practice. And what he practices, he takes into the game. I believe there is some tweaking there as far as practice habits and what he practices."
• Meanwhile, Halladay himself took the hill for an important rehab start tonight. Reviews were not promising, with CSNPhilly.com's Jim Salisbury reporting (via Twitter) that Halladay managed only 52 strikes in 90 pitches, allowing seven hits and three walks while striking out four. According to Salisbury, also via Twitter, Halladay "does not look ready." Gelb concurred with that assessment, though he noted that Halladay seems determined to start for the Phils on Sunday. (Twitter links.) For more details on Halladay's evening, see this piece from David Murphy, Gelb's colleague with the Inquirer.
• Another Philadelphia starter is headed in the opposite direction, with Todd Zolecki of MLB.com reporting that John Lannan will be shut down for the season and is likely headed for surgery. Assistant GM Scott Proefrock said that he believes Lannan "ruptured [a] tendon" in his left knee. Already a non-tender candidate, the 28-year-old struggled to a 5.33 ERA over 74 1/3 innings in his first year in Philadelphia and could be left looking for a minor league deal for 2014.
