On the flip side, the Cards’ apparent lack of interest in Castellanos may signal that they simply prefer Ozuna, who is both a comparable talent and is a more known quantity to the Cardinals’ staff and front office.  Recent reports suggest that the Cards, Reds, and Rangers are all still in the mix for Ozuna, while Texas also has some interest in Castellanos, but perhaps only as a first baseman.  Along with Josh Donaldson, Castellanos and Ozuna are the headliners of a rapidly-depleted free agent crop as we approach the middle of January, and it will be interesting to see which clubs (perhaps a known suitor or a mystery team) wind up with these big bats.

Some more from around baseball…

• Richard Urena was recently acquired by the Orioles on a waiver claim, though the infielder could have theoretically ended up in the black and orange five years ago, MASNsports.com’s Roch Kubatko writes.  When the Blue Jays considered the possibility of trading prospects to Baltimore as compensation for hiring Dan Duquette out of his contract as the O’s executive VP of baseball operations, Kubatko notes that Urena was one of the names the Jays offered.  Talks never went anywhere, however, and Toronto instead hired Mark Shapiro as its new president and CEO in mid-2015.  As for Urena, he stands a good chance at winning a bench job in Baltimore, as the Orioles were in need of a backup shortstop option behind Jose Iglesias.
• Another Orioles move could also be on the way, as Kubatko reports that the team is close to adding an experienced catcher.  It’s probably safe to assume that this will be a minor league signing, as the Orioles already have a fair amount of catching depth with Chance Sisco, Pedro Severino, and Austin Wynns lined up behind the plate.
• The Mets announced earlier this week that former infielder Reid Brignac will manage the single-A Columbia Fireflies in 2020.  This will mark the first managerial or coaching gig for Brignac, who retired in mid-2018 following a 15-year playing career.  Brignac appeared in 369 Major League games over parts of nine seasons, suiting up for six different teams but seeing most of his action (256 games) with the Rays from 2008-12.  Brignac will have a couple of other familiar names joining him on Columbia’s staff, as Jerome Williams was named the new pitching coach and Mariano Duncan will be the Fireflies’ new hitting coach.

Now 37, Williams hasn’t suited up for a major league team since 2016, when he threw 17 1/3 innings with the Cardinals. Williams spent parts of the past two seasons pitching in Venezuela, Mexico and with the Somerset Patriots of the independent Atlantic League. However, the right-hander did enjoy a long career in the majors, during which he recorded a 4.59 ERA across 1,029 2/3 innings (236 appearances, 149 starts) and amassed at least 100 frames in seven seasons. Known for sporting a puka shell necklace and a pink glove, Williams nobly used his time in the spotlight to raise awareness for cancer in honor of his mother, who passed away of breast cancer in 2001.

A first-round pick of the Giants in 1999, Williams was their top-ranked prospect twice (in 2000 and ’01) and was also among baseball’s 50 best farmhands three times (2000-02), according to Baseball America. Williams debuted in San Francisco in impressive fashion in 2003, when he put up a stingy 3.30 ERA and totaled 2.0 fWAR over 131 innings and 21 starts, though he wasn’t able to replicate that success over the rest of his career.

After Williams’ effectiveness dipped in his second and third seasons, the Giants traded him (and David Aardsma) to the Cubs in 2005 for reliever LaTroy Hawkins. That was the first in a long line of big league transactions Williams was part of, though it was the only trade involving him. Along with the Giants, Cubs and Cardinals, Williams pitched for the Nationals, Angels, Rangers, Astros and Phillies at baseball’s highest level. The nomadic Williams also took the mound in pro leagues in Puerto Rico, Taiwan and Long Beach, Calif.

MLBTR congratulates Williams on an interesting playing career and wishes him the best in his attempt to join the coaching ranks.

Williams seemingly waited to sign after undergoing a procedure on his Achilles tendon. He’ll now begin working towards making the Cardinals the eighth team with which he’s seen major league action. Williams will start out with the club’s top affiliate.

For St. Louis, Williams represents a swingman option. He has exceeded 100 innings in each of the last three seasons, and may be the type of steady piece needed for a staff has shown some cracks. Williams scuffled to a 5.24 ERA last year with the Phillies, but had carried a 4.54 earned run mark (with 6.1 K/9 against 2.7 BB/9) in the 466 innings he threw over the prior four seasons.

Let’s check in on a few other free agents that have yet to sign:

• The Rockies aren’t “especially aggressive” at present in their pursuit of free agent righty Yovani Gallardo, Chris Cotillo of SB Nation tweets. He had previously suggested that Colorado may be a finalist for Gallardo’s services, but now says it is not clear how serious the club is about chasing Gallardo. The veteran remains the most established starter left on the market.
• The Mets are still interested in adding to their bullpen, but probably not at the price that Tyler Clippard is likely to command, Mike Puma of the New York Post reports on Twitter. Puma previously tweeted that New York was keeping an eye on Tommy Hunter, but was not looking to go past a one-year deal. Hunter, though, has been looking for more.
• Righty Jerome Williams will miss time early in the year after undergoing a procedure on his Achilles tendon, Cotillo tweets. The 34-year-old hurler has logged better than 100 innings in each of the last four seasons, and could still hold appeal as a swingman/depth option.

“It was kind of nerve racking.  Going through a season where I was with the Angels and I felt like things would have gotten done earlier, I proved to people that I could [start and pitch out of the bullpen] at that time.  I was the only pitcher that had 25 starts and ten relief appearances, I think I was thinking at that time that people would come out and offer me something and it didn’t happen.  It was kind of nerve racking but we got it done and that’s all that mattered,” Williams told MLBTR in the Phillies’ Clearwater clubhouse.

Even though he was biting his nails a bit, Williams says he wasn’t phoning agent Larry O’Brien to get constant updates.  The Full Circle Sports Management rep has been in the field for more than 30 years and, as Williams put it, “he knows what he’s doing.”  Indeed, O’Brien was relentless in his efforts to find a suitable deal for Williams and eventually he found a solid one-year platform for him to showcase his talents.

Unfortunately, things didn’t work out in Houston and the next stop in Texas wasn’t fruitful, but he found success with the Phillies when he landed there in August.  In nine starts for Philadelphia, Williams pitched to a 2.83 ERA with 6.0 K/9 and 2.7 BB/9 across 57 1/3 frames.  After ending the year on a high note, Williams jumped at the chance to skip the free agent process and stick with the Phillies with a one-year, $2.5MM contract extension.

“This was a no-brainer for me,” Williams explained. “Playing with them for the couple months I was with them, it was a no-brainer.  The atmosphere, the guys in the clubhouse, the city, it was a no-brainer to come back.”

Williams credited his Philadelphia battery mates Carlos Ruiz and Wil Nieves for his improved performance to close out the year.  His comfort level with the Phillies also helped matters.  With seven different major league stops over the course of his career, Williams knows what he likes in a clubhouse and what he would rather avoid.

“I like being here because everybody treats everybody like family.  When I came in, I was a new guy but I’ve been a long time and I knew a lot of the veteran guys here, so that made the transition a lot easier.  I started talking to Jimmy [Rollins], Chase [Utley], I played with Chase in the [Arizona] Fall League, I played against Marlon [Byrd], I played against A.J. [Burnett], so it’s like, whoa, I know these guys.”

“Just seeing the younger guys mature, it was like a family, so that’s what the clubhouse is all about.  This is your domain, this is our family, this is our place.  So if we can be one as a family and as a unit, we can do things together,” Williams said.

Family is a concept that’s hugely important to Williams.  In honor of his late mother who lost her battle to breast cancer in 2001, he’ll once again be donning a multitude of colorful gloves to raise awareness for different forms of cancer.  Williams’ top choice is pink in recognition of his mother, but he’ll also be mixing it up with four different colors to put the spotlight on prostate, pancreatic, liver, and childhood cancers.

After a stress-free winter and a productive spring, Williams is eager to take the mound in April and build on his strong performance at the close of 2014.  If all goes according to plan, Williams won’t find himself waiting around for a call next winter either.

Williams, who is nearing his 33rd birthday, was quite productive in a short stint with the Phillies this year. Over nine starts for Philadelphia, he logged 57 1/3 frames of 2.83 ERA ball. Of course, that was his third MLB club on the year, and Williams did not put up very attractive numbers in his first two stops with the Astros and Rangers, combining for a 6.71 ERA over 57 2/3 frames.

All said, Williams finished 2014 with 6.4 K/9 against 2.8 BB/9, while posting a cumulative 4.16 FIP, 4.09 xFIP, and 4.03 SIERA. Those numbers provide some reason for optimism, though the Phillies may hope that five better rotation arms emerge from the spring, allowing them to stash Williams as a long man.

Williams was designated for assignment Friday by the Rangers after making a pair of starts. The 32-year-old was outstanding in his Texas debut allowing just one run and no walks over six innings against the best team in the American League, the A’s, but he was shelled by the Indians in his next start (10 runs, 13 hits, and three walks in four innings). After pitching to a 4.46 ERA in 351 innings for the Angels from 2011-13, Williams has struggled to a line of 6.71 ERA, 6.9 K/9, 3.0 BB/9, and 12.0 H/9 in 28 appearances (two starts) for the Rangers and Astros covering 57 2/3 innings.

This is the second time the Phillies have designated O’Sullivan for assignment this season. Before that DFA, the 26-year-old made one start in the nightcap of a doubleheader against the Braves allowing four runs and eight hits in 5 2/3 innings. O’Sullivan regained a 25-man roster spot when the Phillies traded Roberto Hernandez and, in the lone start of his second tour of duty Thursday, surrendered three home runs to the Astros over six innings.

The 32-year-old veteran made a pair of starts for the Rangers and had wildly different results in the two outings. Williams hurled a strong quality start in his first game, yielding just one run on five hits and no walks with four strikeouts in six innings against a tough Oakland lineup. In his second start with Texas, however, the Indians rocked him for 10 runs on 13 hits in just four innings.

Overall, Williams has a 6.71 ERA this season while playing for both Texas teams — the Rangers and Astros. That’s a far cry from the solid work he put together from 2011-13, when he turned in a 4.46 ERA in 351 innings as a swingman for the division-rival Angels.

The Rangers claimed Marks off waivers from the A’s last month, but he appeared in just 5 1/3 innings for the club’s Triple-A affiliate, yielding three runs in that time. Overall, the 26-year-old has posted a 5.03 ERA with 8.5 K/9 and 3.7 BB/9 in 39 1/3 innings this season at the Triple-A level.

Williams signed a minor league deal with the Rangers after being released by the Astros earlier this month. His contract reportedly contained an Aug. 1 opt-out clause, which was thought to be a formality, as Texas was expected to call him up prior to that date. He posted a 4.46 ERA in 351 innings for the division-rival Angels from 2011-13, but he struggled to a 6.04 ERA in 47 frames for Houston earlier this year.

3:20pm: The Rangers have signed Jerome Williams to a minor league deal and assigned him to Triple-A Round Rock, senior vice president of communications John Blake announced (on Twitter).

Williams, a client of Full Circle Sports Management, signed a one-year, $2.1MM contract with the Astros this offseason but found himself released earlier this week after posting a 6.04 ERA in 47 2/3 frames with Houston. The veteran swingman is plenty familiar with the AL West, as prior to his time in Houston, he had some success with the 2012-13 Angels, notching a 4.57 ERA in 307 innings (40 starts, 29 relief appearances).

The 32-year-old Williams has seen time with the Giants, Cubs, Nationals, Angels and Astros to this point in his career, and given the outbreak of injuries among Rangers pitchers this year, it seems likely that he could get a crack in the big leagues with Texas as well. The Rangers have lost Derek Holland, Matt Harrison and Martin Perez for the season, while Tanner Scheppers, Nick Martinez and Alexi Ogando are currently on the disabled list. Veteran lefty Joe Saunders, who made eight starts for the Rangers, was just released and hooked on with the Royals. All told, the Rangers have played 92 games this season and deployed 12 different starting pitchers.

Williams has a career 4.45 ERA with 5.8 K/9, 3.2 BB/9 and a 48.4 percent ground-ball rate in 824 innings of work at the Major League level.

Here’s more from the AL West:

• The Astros are interested in upgrading the club’s bullpen in both the short and long-term, reports MLB.com’s Brian McTaggart. Owner Jim Crane said that the team’s relief corps has cost the club ballgames, indicating that he hopes to find some solutions during the current season. Nevertheless, any moves would keep an eye firmly on the future: “We’re always looking more long term,” he said, “but we want to try to establish a nucleus this year and win a lot more ballgames than we did last year.”
• Of course, the Angels’ bullpen needs are on a much shorter fuse. Even after making several recent acquisitions, club GM Jerry Dipoto says that the team is still browsing the market, according to Jeff Fletcher of the Orange County Register (via Twitter). Dipoto hopes to form a late-inning nucleus that can record the “last nine outs” of a game. “We will continue to look for a guy who can join that group,” he said.
• Multiple teams have expressed interest in Mariners righty Erasmo Ramirez, Bob Dutton of the Tacoma News Tribune reports on Twitter. The 24-year-old has not had sustained success at the major league level, but does offer plenty of youth and team control. Ramirez would seem to make a useful trade chip in a lower-level deal for Seattle, or as a part of a package in a larger swap.

• Righty Jerome Williams has been released by the Astros, according to the MLB.com transactions page. The 32-year-old swingman owns a 6.04 ERA through 47 2/3 innings (all as a reliever) on the year for Houston, with 7.2 K/9 against 3.0 BB/9. Across nine MLB seasons, he has allowed 4.45 earned runs per nine while working mostly as a starter.
• The Phillies have agreed to a minor league deal with Jo-Jo Reyes, reports MLBTR’s Zach Links (via Twitter). The 29-year-old lefty has seen time in parts of five MLB seasons, the last of which came in 2011. He owns a 6.05 career ERA with 5.8 K/9 and 3.9 BB/9 through 334 2/3 innings, mostly as a starter. Reyes has been playing in Korea since the start of the 2013 season.
• The Orioles have outrighted righty Ramon Ramirez to Triple-A, the club announced. Ramirez got just one inning during his time with Baltimore, though he has seen action in parts of nine MLB seasons.
• After being designated for assignment by the Blue Jays on Sunday, outfielder Brad Glenn has cleared outright waivers and been assigned to Triple-A, reports Brendan Kennedy of the Toronto Star (via Twitter). The 27-year-old notched his first MLB hit during a brief call-up.
• The DFA rolls are growing, with the following players are currently in limbo (per MLBTR’s DFA tracker): Justin Maxwell (Royals), Jeff Francis (Athletics), Rich Hill (Angels), Raul Fernandez (Rockies), Alfonso Soriano (Yankees), Brad Mills (Athletics), Donnie Murphy (Rangers), George Kottaras (Indians), John Buck (Mariners), and Mark Lowe (Indians).

Williams, a 32-year-old righty, signed a one-year, $2.1MM deal with Houston before the season. He owns a 5.91 ERA through 45 2/3 innings with the club, all in relief. He does own superior peripherals (7.1 K/9 against 3.0 BB/9) than those that he carried as a starter in previous seasons, and some ERA estimators looked more favorably on his work (4.70 FIP, 4.09 xFIP, 3.72 SIERA).

MONDAY, 2:00pm: Evan Drellich of the Houston Chronicle tweets that the Astros signed Williams to be a starting pitcher.

1:54pm: Cotillo tweets that Williams will take his physical on Wednesday. He received a one-year, incentive-laden Major League deal, Cotillo adds.

1:40pm: The Astros have agreed to terms with right-hander Jerome Williams, pending a physical, according to MLB Daily Dish's Chris Cotillo (on Twitter). Williams is a client of Full Circle Sports Management.

Williams, 32, posted a 4.57 ERA in a career-high 169 1/3 innings for the Angels last season. The ground-ball specialist and veteran swingman made a career-high 25 starts, averaging 5.7 K/9 and 2.9 BB/9 while posting a 47.1 percent ground-ball rate — a slight departure from his career mark of 48.6 percent. The Astros will look to improve Williams' bloated home-run rate and struggles to strand baserunners — two areas in which he's been considerably below the league average since making his return to the Majors with the Angels.

The Angels elected to non-tender the big righty rather than pay his projected arbitration salary of $3.9MM. Williams has five year, 49 days of service time, meaning he does not have any years of arbitraion eligibility left and will therefore be a free agent upon completion of his one-year contract with Houston.

The former supplemental-round pick (No. 39 overall by the Giants in 1999) didn't throw a pitch in the Majors from 2008-10 but resurfaced with the Halos in 2011 and has posted a 4.46 ERA in 351 innings in that time. During his hiatus from the Majors, Williams bounced around the minor leagues and found himself pitching in two different independent leagues before finding his way back to a big league mound.

With the Astros, he could serve as a swingman as he has with the Angels for the past three seasons, or he could compete for a spot in Houston's rotation. The Astros figure to have Scott Feldman, Jarred Cosart, Brett Oberholtzer and Brad Peacock in the rotation, with Dallas Keuchel, Lucas Harrell, Collin McHugh and Alex White among the names competing for the fifth spot (as examined over at SB Nation's Crawfish Boxes earlier this morning). Williams could open the season in the rotation and be shifted back to the bullpen should one of Houston's top prospects (e.g. Mark Appel or Mike Foltynewicz) force his way onto the big league staff.

Here are a few bits of information elsewhere on the current free agent pitching market:

• Bronson Arroyo and the Dodgers have had discussions since Masahiro Tanaka chose not to sign with Los Angeles, tweets Jon Heyman of CBSSports.com. The level of interest remains uncertain, Heyman notes.
• The Angels have "a bit" of interest in Arroyo but are also content to take their current group to Spring Training, tweets Jon Heyman of CBS Sports. The Angels acquired Hector Santiago and Tyler Skaggs this offseason to join Jered Weaver, C.J. Wilson and Garrett Richards in the rotation.
• It's been a different type of offseason for the Angels this year, writes MLB.com's Alden Gonzalez, noting the patience and restraint the team has shown on the free agent market. Gonzalez notes that the Angels aren't interested in Matt Garza at the $13MM AAV he would receive in his near-deal with the Brewers, as it would push them up against the luxury tax threshold. He lists Arroyo, Jason Hammel, Chris Capuano, Scott Baker and Paul Maholm as potential rotation options that would leave some cushion between Anaheim's payroll and the luxury tax.
• With a lot of starters still available on the open market, there are plenty of teams that have yet to fill up their slate of rotation candidates. Joining the O's and Jays among the clubs that are looking for starters are both of Chicago's two franchises, according to Bruce Levine of 670thescore.com (via Twitter). Levine indicates that the Cubs are looking over the list of remaining free agents, but he does not say whether the White Sox have any interest in open-market players.
• MLB.com's Greg Johns tweets that Mariners GM Jack Zduriencik thinks the team is done making "major" additions, but tweaks are still possible. However, semantics could come into play heavily, as manager Lloyd McClendon said the team would still like to add a No. 3 starter, per ESPN 710's Shannon Drayer (Twitter link). New team president and COO Kevin Mather indicated today that the club would have the financial resources necessary to make more additions before the start of the season.
• There are five clubs vying for the services of Hammel, tweets Chris Cotillo of MLBDailyDish.com. Hammel is expected to choose a landing spot within a week.
• Swingman Jerome Williams has offers on the table from at least three clubs, Cotillo tweets. He, too, appears to be nearing a decision point.
• Southpaw reliever Tim Byrdak will not be re-signing with the Mets, the reliever tweeted (via Adam Rubin of ESPNNewYork.com). The 40-year-old indicated that the team decided against signing him.
