With about 20% of the 2023 regular season already in the books, here are three things we’ll be keeping an eye on around the baseball world throughout the day today:
1. Mervis to debut:
The Cubs are reportedly set to call up first base prospect Matt Mervis to the major league team ahead of this afternoon’s game against the Marlins. Mervis broke out in a big way in 2022, advancing from High-A all the way to Triple-A over the course of the season, with his strikeout and walk numbers improving as he advanced through the levels of the minors. In all, Mervis has slashed .293/.387/.573 in 367 plate appearances at the Triple-A level, with 21 home runs in just 85 games. While power is Mervis’s primary calling card, he’s also shown remarkable discipline at the plate, with a strikeout rate of 15.8% and a walk rate of 12% at the Triple-A level in his career so far.
Mervis figures to draw regular starts at first base, where veteran Eric Hosmer was signed over the offseason to act as a bridge to Mervis. Hosmer has struggled with the Cubs so far this season, slashing just .250/.294/.363, good for a wRC+ of 79. Hosmer is also striking out at a 24.7% rate that would be a career high for the 33-year-old veteran if it continued over the full season, while walking at just a 5.9% rate that would be his lowest in a full season, with only the shortened 2020 season clocking in lower at 5.8%. A 40-man roster move won’t be necessary to accommodate Mervis, as the club’s 40-man roster stands at 39 currently. Still, a move of some sort will be necessary to add Mervis to the active roster.
2. Wainwright to return:
The Cardinals are set to receive a boost to their pitching depth this weekend when veteran right-hander Adam Wainwright is activated to start Saturday afternoon’s game against the Tigers. Wainwright, who posted a decent 3.71 ERA (104 ERA+) with a 3.66 FIP last season, figures to help stabilize a Cardinals rotation that has been a major reason why the club’s 4.70 ERA is bottom ten in the majors this season. At 41 years old, age-related decline is always a possibility, but Wainwright has already battled back from a difficult stretch of seasons in his mid-thirties to produce a 3.57 ERA (112 ERA+) since the start of the 2019 season, giving reason for optimism that Wainwright can remain productive in this final season of his career. Wainwright’s return couldn’t come at a better time for the Cardinals, who have lost six straight games and 13 of their last 16.
3. Glasnow headed for rehab:
Oft-injured Rays ace Tyler Glasnow figures to begin a rehab assignment for the club’s Triple-A affiliate in Durham today, with a return later this month as a potential target. Glasnow has been on the injured list all season after suffering an oblique strain during Spring Training. Though injuries have limited Glasnow to just 212 2/3 innings of work since the beginning of the 2019 season, those innings have been phenomenal, with a 2.75 ERA (151 ERA+) and a 2.87 FIP with a fantastic 36% strikeout rate and a walk rate of just 7.8%.
Upon his return, Glasnow will join a rotation that last Jeffrey Springs to Tommy John surgery earlier this season alongside Shane McClanahan, Drew Rasmussen, and Zach Eflin. The likes of Josh Fleming, Yonny Chirinos, and the recently acquired Chase Anderson are among the club’s bulk options who have filled out the rotation so far this season, though McClanahan, Rasmussen, and Eflin are the only regular starters currently on the roster.
