Aaron Wilkerson

KBO’s Lotte Giants Re-Sign Aaron Wilkerson

By | at

The Lotte Giants of the Korea Baseball Organization announced Thursday that they’ve re-signed righty Aaron Wilkerson to a one-year deal for the 2024 season (English link via Jee-ho Yoo of the Yonhap News Agency). He’ll be guaranteed $750K and can take home another $200K of incentives.

Wilkerson, 34, logged big league time with the Brewers each season from 2017-19 but posted  a 6.88 ERA in a combined 35 1/3 innings. He’s since pitched in Triple-A with the A’s and Dodgers in addition to stints in Japan’s NPB and, in 2023, in the KBO.

His first year of KBO ball was a strong one. The 6’3″ righty joined the Giants midseason and made 13 starts with a sterling 2.26 ERA in 79 1/3 frames. Wilkerson fanned 24.8% of his opponents against a tidy 6.1% walk rate alongside a strong 56.1% grounder rate.

The journeyman righty, who’s pitched in four different MLB teams’ minor league systems in addition to stints in indie ball and in Asia, will now take home a nice seven-figure salary that can reach nearly $1MM — a nice windfall at this stage of an 11-year grind through professional ball.

Perhaps he can further parlay strong overseas results into an MLB return in his late 30s. Even if that’s not in the cards for Wilkerson, a nice 2024 campaign would likely put him in position to re-sign in the KBO and continue earning at levels he’s rarely, if ever seen to this point in his career.

KBO’s Lotte Giants Sign Aaron Wilkerson, Release Dan Straily

By | at

The Lotte Giants of the Korea Baseball Organization announced an agreement with right-hander Aaron Wilkerson this morning (h/t to Jeeho Yoo of Yonhap News). He’ll be paid $350K through season’s end.

Wilkerson, 34, has pitched professionally since 2013. He logged 14 big league appearances, all of which came with Milwaukee between 2017-19. Wilkerson spent part of last season in Japan with the Hanshin Tigers before returning to the U.S. for 2023. He’d been in the A’s system on a minor league pact, working to a 6.51 ERA through 47 innings with Triple-A Las Vegas.

The A’s granted Wilkerson his release last week. That was apparently so he could pursue the KBO opportunity, which’ll be the first of his career. (Oakland subsequently signed righty Zack Godley as non-roster rotation depth). Wilkerson has a 4.02 ERA over parts of five Triple-A seasons, striking out just under a quarter of opponents in the process.

In a corresponding transaction, Lotte released veteran righty Dan Straily. KBO teams are permitted a maximum of three foreign-born players (two pitchers) on the roster. The Giants will move forward with Charlie Barnes and Wilkerson. Straily has spent four of the last five seasons with Lotte. He was effective for the bulk of that time, including a 2.50 ERA in 2019 and a 2.31 mark over 11 starts after re-signing last August.

Straily hasn’t quite found his groove in 2023, however. He has a 4.37 ERA with a 19.2% strikeout rate and elevated 10.2% walk percentage through 80 1/3 innings. That led the Giants to move on and put Straily back on the open market. The 34-year-old was in affiliated ball last season, spending some time with the Diamondbacks’ Triple-A club. He hasn’t pitched in the majors since an eight-year run from 2012-19.

NPB/KBO Signings: 12/7/21

The latest on players inking contracts with Nippon Professional Baseball or the Korea Baseball Organization…

  • NPB’s Hanshin Tigers announced earlier this week that right-hander Aaron Wilkerson has been signed.  Wilkerson is a veteran of three Major League seasons, posting a 6.88 ERA over 35 1/3 innings with the Brewers from 2017-19.  He didn’t see any action in 2020, and after signing a minor league deal with the Dodgers last May, posted a 3.86 ERA and some very impressive strikeout (27.9%) and walk (5.4%) rates over 112 innings with Triple-A Oklahoma City.  This performance didn’t get Wilkerson another look at the Show, however, and the 32-year-old will now explore this new opportunity in Japan.  Wilkerson came close to signing abroad last winter, as he had a deal in place with the Chinese Professional Baseball League’s Rakuten Monkeys before ultimately opting out of the contract.
  • Right-hander Albert Suarez is making the jump from Japan to South Korea, as he has signed with the KBO League’s Samsung Lions.  The one-year deal will pay Suarez $700K in salary, a $100K signing bonus, and another $200K is available in contract incentives.  Suarez’s MLB resume consists of 115 2/3 innings of 4.51 ball with the Giants in 2016-17, but he has pitched considerably better since joining NPB’s Yakult Swallows prior to the 2019 season.  Over Suarez’s three seasons with the Swallows, he posted a 3.00 ERA over 162 innings, culminating in his role in helping the Tokyo-based team capture the Japan Series this past season.

Minor MLB Transactions: 5/10/21

Catching up on some minor league moves from around baseball…

  • The Astros have signed righty Michael Kelly to a minor league pact, Chandler Rome of the Houston Chronicle tweets. Kelly was the 48th overall pick of the Padres in the 2011 draft, but he hasn’t made it to the bigs thus far. Along with the Padres, the 28-year-old appeared in the minors with the Orioles through 2018, recording a 5.35 ERA over 607 2/3 innings. Kelly’s most recent professional action came in 2019 with the Southern Maryland Blue Crabs of the independent Atlantic League.

Earlier updates:

  • The Dodgers signed right-handers Kevin Quackenbush, Austin Bibens-Dirkx, and Aaron Wilkerson to minor league contracts earlier this month, and all are on the roster for the team’s Triple-A affiliate.  Quackenbush is the most experienced of the trio, with 207 2/3 MLB innings with the Padres and Reds from 2014-18, and the 32-year-old is back in the Dodgers organization after previously pitching for Triple-A Oklahoma City in 2019.  Bibens-Dirkx was a member of several organizations before catching on with the Rangers in 2016 and posting a 5.27 ERA over 114 1/3 innings from 2017-18.  Wilkerson appeared in parts of three Major League seasons with the Brewers from 2017-19, posting a 6.88 ERA over 35 1/3 frames of work.
  • The Indians signed right-hander Matt Koch to a minor league deal back in April.  Koch pitched for the Yakult Swallows in 2020, posting a 7.88 ERA over 16 innings with the Japanese club.  Formerly a member of the Diamondbacks, Koch pitched 86 2/3 of his 125 1/3 career Major League innings in 2018, when he had a 4.15 ERA/4.85 ERA while starting 14 of his 19 games for Arizona.  For his overall career, Koch has a 4.88 ERA at the big league level.

Outrighted: Ramirez, Wilkerson

By | at

The tidal wave of September call-ups earlier this week resulted in nearly two dozen players being designated for assignment to create space on 40-man rosters throughout the league. While some of those players will be claimed by new organizations, we’ll track Wednesday’s collection of players who went unclaimed in this post:

  • Right-hander Neil Ramirez cleared waivers and was assigned outright to the Blue Jays’ Triple-A affiliate, per the International League transactions log. Ramirez averaged 11 strikeouts per nine innings pitched with the Indians in 2018 (51 strikeouts in 41 2/3 innings) but has bounced all over the league dating back to 2016. His ability to miss bats has continually intrigued clubs, but Ramirez has also been far too prone to both walks and home runs. In 25 innings between Cleveland and Toronto this season, he posted a 5.40 ERA with a 24-to-15 K/BB ratio and seven home runs allowed.
  • The Brewers assigned right-hander Aaron Wilkerson to Triple-A San Antonio after he went unclaimed on waivers, per a team announcement. The 30-year-old was very good in 76 1/3 innings spanning 17 starts in San Antonio in 2019, logging a 3.42 ERA with 9.6 K/9, 3.4 BB/9, 1.18 HR/9 and a 37.5 percent grounder rate. However, Wilkerson also allowed 13 runs in 16 big league innings this year and was tagged for 10 runs in nine MLB frames a season ago. He’s enjoyed plenty of success in the upper minors dating back to 2017 but owns just a 6.88 ERA with 28 strikeouts, 13 walks and nine home runs allowed in 35 1/3 innings as a Major Leaguer.

Brewers Activate Nelson, Suter; Designate Wilkerson, Stokes

By | at

The Brewers announced they have reinstated right-hander Jimmy Nelson and left-hander Brent Suter from the 60-day injured list. To create 40-man roster space, the club has designated right-hander Aaron Wilkerson and outfielder Troy Stokes, Jr. for assignment. The club also confirmed the previously-reported designation of right-hander Jeremy Jeffress.

Nelson, the former staff ace, has worked out of the bullpen on rehab, where he’ll presumably factor in down the stretch. He’s battled velocity loss and ineffectiveness in the wake of 2017 shoulder surgery. Suter, too, figures to work in short stints as he returns from 2018 Tommy John Surgery. He’s worked primarily as an opener on rehab, although he did work his way up to four innings in his most recent minor-league start. The soft-tossing lefty was a solid back-end command artist for the club before going under the knife, which would be valuable for a rotation that has undergone its fair share of struggles in 2019.

To welcome back the veterans, Milwaukee cuts bait with Wilkerson and Stokes. Wilkerson’s a 30 year-old swingman whose logged 35.2 subpar innings for the club the past three seasons. He has long been an adequate high minors starter though, explaining why he’s lasted three years on Milwaukee’s 40-man.

Stokes, a former fourth-round pick, has emerged as a noteworthy prospect in Milwaukee’s system the past few seasons. Featuring above-average raw power and speed, per Fangraphs’ prospect duo, Stokes had generally shown solid power and walk rates in the low minors. He hit a speed bump in his first taste at Triple-A, though, where his .233/.341/.385 line was 20% below PCL average. That proved too much for Milwaukee’s taste for a player who has increasingly seen time in left field, not center, in recent years, likely due to a below-average arm. That said, it’s easy to imagine a non-contender taking a chance on Stokes’ physical gifts and pre-2019 track record, so it’s possible, if not likely, he’ll be claimed off waivers. He comes with two additional option seasons, so there’d be no hurry to get him to the big leagues before he’s ready.

Brewers To Place Zack Davies On IL, Promote Jake Faria

By | at

The Brewers will place righty Zach Davies on the 10-day injured list, per Robert Murray of The Athletic (Twitter links). His precise injury situation isn’t yet clear, but it seems he’s dealing with some sort of back ailment.

Also heading off of the active roster is right-hander Aaron Wilkerson, who was optioned to Triple-A. Joining the big-league club are recently acquired Jake Faria and fellow righty Devin Williams, with MLB.com’s Adam McCalvy (via Twitter) reporting the latter’s promotion. Williams will need to be added to the 40-man roster.

Losing Davies is tough news for a Milwaukee club that’s as far out of first place as it has been all year (four games) after a four-game skid. While Davies has had a few rough outings of late, he has paced the team in starts made (23) and innings (122 2/3) while working to a solid 3.74 ERA with 5.7 K/9 and 3.0 BB/9.

ERA estimators have been predicting regression for Davies for some kind. But the Brewers had every reason to keep running him out there and hoping he could continue to generate results, at least until his velo began to droop of late.

It still isn’t known how the club will account for the open rotation spot. Faria has spent time in a starting capacity this year but has been working of late as a reliever. Williams has functioned exclusively in the pen this season. It’s possible recently acquired southpaw Drew Pomeranz could work as a starter (or, at least, in some kind of multi-inning capacity).

Brewers Recall Aaron Wilkerson, Option Jay Jackson

By | at

The Brewers announced a change to their bullpen crew ahead of today’s game against the rival Cubs. Aaron Wilkerson joins the big league club from Triple-A San Antonio, while Jay Jackson has been optioned back to the minors.

Wilkerson, 30, has made five scattered relief appearances since April, unfortunately surrendering earned runs each time out. He has been an effective starter in Triple-A this season, however, going 7-1 with a 3.06 ERA across 14 starts. The Brewers are prepared for a quick hook of Gio Gonzalez today should there be any sign of shoulder trouble, with Wilkerson serving as the contingency plan, notes MLB.com’s Adam McCalvy (via Twitter).

Jackson, 31, has also served as little more than a 25th man while on the major league roster. In ten appearances, Jackson has a 5.79 ERA (4.93 FIP) across 14 innings. The South Carolina native gave Milwaukee some length in July with five two-inning outings, four of which he escaped scoreless.

The Brewers are sticking with an eight man bullpen for now, a necessity given the injuries sustained by the starting rotation. With Jhoulys Chacin, Jimmy Nelson, Brandon Woodruff, and Brent Suter on the injured list, Milwaukee figures to be more reliant than most contenders on players like Wilkerson and Jackson, even as they continue to shuttle them back and forth from San Antonio.

Corbin Burnes Optioned To Triple-A, Aaron Wilkerson Recalled

By | at

The Brewers have optioned Corbin Burnes to Triple-A San Antonio, per MLB Roster Moves. Righty Aaron Wilkerson has been recalled in his stead.

Burnes is among the candidates for most disappointing 2019. After a positive showing in last year’s playoffs, Burnes was ticketed for the rotation this season. Needless to say, things have not gone according to plan for Burnes, who sports a 8.85 ERA. He was sent to the minors after four starts at the beginning of the year in which he surrendered a total 21 earned runs in 17 2/3 innings.

He’s been better since joining the bullpen at the beginning of May, but a couple of blowups ballooned his bullpen ERA to 7.43 in 19 appearances. If we shorten the sample even further, we can get his ERA down to 4.50 in June, and if you squint even harder, a 3.56xFIP starts to look pretty good.

Wilkerson joins the club for the second time this season. The 30-year-old Wilkerson made three appearances in April, surrendering 6 earned runs in 7 1/3 innings.

Brewers Select Jay Jackson, Designate Alex Wilson

By | at

The Brewers have selected the contract of right-hander Jay Jackson from Triple-A San Antonio and opened a spot on the roster by designating right-hander Alex Wilson for assignment, per a club announcement. The Brewers also placed righty Aaron Wilkerson on the 10-day injured list due to a left foot contusion and recalled left-hander Donnie Hart from San Antonio in his place.

Jackson’s promotion marks the culmination of a lengthy journey back to the big leagues for the 31-year-old. The right-hander appeared in six games with the 2015 Padres, totaling 4 1/3 innings of bullpen work, but was cut loose that offseason in order to pursue an opportunity in Japan. The 2008 ninth-round pick could have stuck with the Padres that year in hopes of surviving the offseason and spending the next season as an up-and-down reliever, though there was no certainty or fiscal security associated with that route. Rather, Jackson took a chance on venturing overseas and not only found success, but became one of the most dominant relievers in Japan’s Nippon Professional Baseball over the next three seasons.

In three seasons with the Hiroshima Carp, Jackson pitched to a combined 2.13 ERA with 202 strikeouts against 70 walks in 182 innings as a member of the Carp. He explored the possibility of a return to the U.S. after his second season in Japan but, apparently not finding any offers to his liking, returned for a third season in NPB. Ultimately, the Brewers made Jackson a minor league offer to return to the organization — he’d pitched in their minor league system in 2014 — that the righty accepted.

It’s still early in the Triple-A season, but Jackson has torn through opposing lineups in the Pacific Coast League, pitching 8 2/3 innings of shutout relief with a 14-to-2 K/BB ratio and just four hits allowed. Given the inconsistencies in the Milwaukee ’pen beyond Josh Hader and Junior Guerra, Jackson could very well have a legitimate opportunity to entrench himself in Craig Counsell’s relief corps. Milwaukee has hopes that Jeremy Jeffress, recently activated from the injured list, can help to stabilize matters, but the team has already lost Corey Knebel to Tommy John surgery and designated both Wilson and Jake Petricka for assignment in the past 48 hours.

Wilson, 32, spent Spring Training as a non-roster invitee with the Indians after being non-tendered by the Tigers last December. He didn’t earn a spot in the Cleveland ’pen, however, and later signed on with the Brewers on a big league deal once health concerns in the Milwaukee ’pen began to mount.

Although he’s long been a steady presence in the Detroit bullpen, Wilson was tattooed for a dozen runs on 15 hits (three homers) and nine walks with 13 strikeouts in 11 1/3 frames with the Brewers. He started off with three strong outings in a row before being hammered for six runs his fourth time out, and the right-hander never managed to fully recover. Three of his past four outings have seen him yield a pair of earned runs.

The Brewers will have a week to trade Wilson, release him, or pass him through outright waivers (though he could reject an outright assignment and take free agency instead). His contract reportedly came with a fairly minimal $750K base salary, so even if there’s no 45-day advance consent clause in the deal, the financial loss is hardly prohibitive for the Milwaukee organization.
