MLB Trade Rumors

TODAY: Senga won’t return prior to the All-Star break, Mets manager Carlos Mendoza told DiComo (X link) and other reporters today.

JUNE 7: The Mets and Phillies face off this weekend in MLB’s London Series, and both clubs will be afforded a 27th man for the overseas event. For the Mets, that’ll be infielder Brett Baty, who was recently optioned to Triple-A Syracuse in a move designed to help him get back on track but also to get hot-hitting Mark Vientos a legitimate audition at third base.

While Vientos is clearly outplaying his fellow corner-infield prospect at the moment, it seems the Mets are open to ideas that could keep both in the lineup, even with a full-time designated hitter (J.D. Martinez) and with Pete Alonso entrenched at first base. Baty told the Mets beat this morning that the team has informed him he’ll likely begin taking reps at second base soon down in Syracuse (X link via Newsday’s Tim Healey). It hasn’t happened in a game setting yet, but the Mets approached him about the possibility when he was optioned on May 31.

The potential addition of second base to Baty’s skill set comes at a time when longtime second baseman Jeff McNeil is struggling through the worst results of his career. McNeil, the 2022 National League batting champion, is hitting just .227/.296/.320 this season — about 16% worse than league-average, by measure of wRC+.

The 32-year-old McNeil is in just the second season of a four-year, $50MM extension and thus isn’t in jeopardy of being cut loose, but this is the second straight season his offensive output has declined in notable fashion. McNeil still has elite bat-to-ball skills (11.2% strikeout rate, 87.6% contact rate), but he’s hitting more fly-balls than ever before, which is having an adverse impact on his results. (Fly-balls — at least those in play — are the easiest type of batted ball to convert into an out.) There’s still surely some poor fortune in play, as McNeil’s fly-ball rate is only a few percentage points higher than when he won his batting title, while his .246 BABIP checks in 70 points shy of his career mark. But clearly the Mets have some level of concern, and clearly they’re also still looking at ways for both Baty and Vientos to factor into the long-term plan (particularly if the club ends up re-signing Pete Alonso and thus removing a Vientos-to-first base scenario).

Baty has never played second base in his professional career. He’s logged 250 innings in left field and otherwise spent every defensive inning since being drafted at third base. But with Vientos viewed more strictly as a corner infielder and also batting an outstanding .333/.392/.621 through his first 74 plate appearances this year, the Mets will take a look at the possibility of Baty slotting in elsewhere on the diamond. Baty hit just .225/.304/.325 in 169 turns at the plate prior to being optioned, so he has some obvious work to do on the offensive side of things as well — but it’s nevertheless interesting to see the Mets experimenting with the defensive alignment in a manner that could accommodate two of the organization’s longtime top prospects who have previously had the same primary position.

Both Baty and Vientos have the potential to emerge as cornerstones in Queens, and if they’re able to do so they’ll likely slot in alongside catcher Francisco Alvarez in forming a young core of hitters around which president of baseball ops David Stearns can build. Alvarez has been out since mid-April, when he required surgery to repair a torn ligament in his thumb. He’s been on a minor league rehab assignment and had been slated for a return early next week. However, Anthony DiComo of MLB.com reports that Alvarez’s return will be delayed by at least a few days. There’s no setback or new injury, but Alvarez has flown home to Venezuela to tend to a family matter.

At this point, there’s no indication Alvarez will be delayed long. A return in latter half of next week still seems feasible. The 25-year-old has already appeared in five minor league games but could get a few more under his belt before being activated. He hit .236/.288/.364 in 16 games before incurring his injury but swatted 25 homers in 123 games (423 plate appearances) last season. Alvarez has hit for a subpar .212 average in 496 big league plate appearances but makes plenty of hard contact, draws a roughly average number of walks, has clear plus power and has made substantial defensive improvements in the past couple years.

In further Mets injury news, there’s some optimism with regard to Kodai Senga’s lengthy rehab process. He’s slated to throw a bullpen session next Monday or Tuesday, tweets Mike Puma of the New York Post. Originally placed on the IL due to a moderate capsule strain his right shoulder, Senga has encountered multiple setbacks along the way. He progressed to facing live hitters by late April but was scaled back to try to get his mechanics back in order. While going through that step, Senga sustained a triceps injury that necessitated a cortisone injection and another five-day shutdown period.

That latter setback came in late May, but the silver lining was that his ailing shoulder looked to be healed on that MRI. It seems both the shoulder and triceps are now approaching a point where he’ll be cleared to throw. There will still be multiple steps to check off before Senga is a realistic option to return to the Mets’ rotation. He’ll likely need multiple bullpen sessions, followed by live sessions against hitters and then a minor league rehab assignment that figures to last multiple starts (with a full slate of rest between each, of course). It seems unlikely he’d be able to check all those boxes by the end of this month, making a July return far more likely.

Senga, 31, is in the second season of a five-year, $75MM contract. The former NPB standout made the All-Star team last year in his rookie season. He also finished second in NL Rookie of the Year voting and seventh in NL Cy Young voting after pitching 166 1/3 innings of 2.98 ERA ball with a 29.1% strikeout rate, 11.1% walk rate, 44.7% grounder rate and 0.92 HR/9.
