Abreu could receive more days off or see more time at DH during the 2024 season, Matt Kawahara of the Houston Chronicle reports.

Abreu had a disappointing 2023 campaign-- his first in Houston -- as he posted a career-worst 86 wRC+ and .295 wOBA. At least a portion of his struggles have been apportioned to a back injury that he dealt with for much of the season and played through until a stint on the injured list in mid-August. The Astros appear to be taking a proactive approach to managing Abreu's workload in 2024, though it's currently unclear if that means he will lose at-bats or just means that he will shift to DH. In either scenario, Jon Singleton or Trey Cabbage could pick up some extra plate appearances.

Singleton is out of minor-league options and could have the first chance on the big-league roster as a result, Chandler Rome of The Athletic reports.

Singleton had a standout game in which he hit two home runs and drove in five on Aug. 11, but his 105-plate appearance sample in the majors last year was otherwise unproductive. He maintained just a .165/.267/.264 line, though his 0.57 BB/K and .194 BABIP suggest he may have deserved better results. Singleton's most direct competition for a spot on the roster is likely to be the recently acquired Trey Cabbage.

Guerrero will make $19.9 million in 2024 after winning his arbitration case against the Blue Jays on Wednesday, Shi Davidi of Sportsnet.ca reports.

It's the largest salary ever awarded by an arbitration panel, although the amount falls well short of the $31 million deal Juan Soto reached with the Yankees in January to avoid arbitration. Guerrero's numbers dropped in nearly every statistical category last season compared to the marks he set in 2022, but the slugging first baseman will receive a $5.4 million raise nonetheless. Guerrero remains a high-value fantasy asset, but his stellar 2021 campaign is beginning to look more like an anomaly than a season off which we should base expectations.

Santana signed a one-year, $5.25 million contract with the Twins on Friday, Jon Heyman of the New York Post reports.

Last season marked Santana's best year at the plate since 2019, as he slashed .240/.318/.429 with 23 homers and 86 RBI between the Pirates and Brewers. The 37-year-old gives the Twins an experienced option in the first base/DH mix alongside younger players Alex Kirilloff (shoulder), Trevor Larnach and Jose Miranda (shoulder).

Kirilloff (shoulder) is on track for live at-bats in February and hopes to be game-ready when the Twins' spring training schedule begins, Dan Hayes of The Athletic reports.

Kirilloff underwent surgery in October to repair the labrum in his right shoulder, but the operation wound up being less invasive than initially expected. He began hitting in January and has been ramping things up of late. Kirilloff projects as the starting first baseman assuming he's ready to roll Opening Day, but nothing is assured given his history of health issues.

Walsh signed a minor-league contract with the Rangers on Thursday that includes an invitation to spring training.

Walsh had a breakout 2021 campaign when he slugged 29 home runs and made the All-Star team. Since then, though, he's managed a lowly .613 OPS and 32.1 percent strikeout rate across 572 plate appearances at the major-league level. The 30-year-old will compete for a reserve role with the Rangers but almost surely will report to Triple-A Round Rock to start 2024 as he looks to get his career back on track.

Rivas was designated for assignment by the Angels on Tuesday, Sam Blum of The Athletic reports.

The Halos needed to free up a spot on the 40-man roster for the addition of Robert Stephenson. Rivas was claimed off waivers a month ago by the Angels and will now go through the waiver process again. The 27-year-old has slashed .243/.324/.349 over parts of three big-league seasons.

Aranda could be in line to serve in a strong-side platoon at designated hitter for the Rays, Adam Berry of MLB.com reports.

It sounds as if Aranda is the top candidate to step into the role vacated by Luke Raley as the DH versus righties and occasional first baseman. A trade of Harold Ramirez, which seems likely, could further clarify Aranda's role. Aranda has posted just a .656 OPS over 190 plate appearances during his limited chances at the major-league level, but the 25-year-old sports a .328/.421/.565 batting line with 43 home runs over the last two seasons at Triple-A Durham. Even if the left-handed batter sits regularly against southpaws, he boasts big fantasy potential.

Lowe signed a one-year, $7.5 million contract with the Rangers on Thursday to avoid arbitration, Kennedi Landry of MLB.com reports.

Lowe's .850 OPS in 2022 looks to be an outlier after he posted a .774 OPS last season, but he's settled in as a strong contributor in runs and RBI while swatting high-teens homers. He earned over a $3 million raise in his second year of arbitration eligibility and will remain under team control through the 2026 campaign.

Mountcastle signed a one-year, $4.1 million deal with the Orioles on Thursday to avoid arbitration, Jon Morosi of MLB Network reports.

Mountcastle has developed into a steady player, posting a slugging percentage above .450 in three of his four big-league seasons. He may lose some playing time in 2024 due to the depth in the Orioles' lineup, but he projects to regularly serve as the team's designated hitter or first baseman.
