Mets Notes: Vientos, Manaea, Outfield

Mets third baseman Mark Vientos, out more than three weeks due to a hamstring strain, tells the team’s beat that he expects to be activated from the injured list tomorrow (via Will Sammon of The Athletic). The Mets will need to make a decision as to how they’ll create active roster space for Vientos. Fellow young infielders Brett Baty and Ronny Mauricio are both struggling at the moment, as is outfielder/designated hitter Jared Young.

The 25-year-old Baty shook off a terrible start to the season, finding his swing in mid-April and slashing .296/.352/.580 over his next 89 plate appearances. That production came in a fairly limited role — those 89 turns at the plate came over a span of about six weeks — but it was encouraging from the former top prospect. He’s since fallen back into a swoon, hitting just .179/.233/.299 this month (albeit with five hits in his past three games).

Mauricio, 24, has popped three homers in 62 plate appearances but slashed only .224/.274/.414 overall. He’s fanned at a 30.6% clip and has just eight hits in his past 41 plate appearances (including a home run last night). That marks his first MLB action since 2023. He missed the entire 2024 season after suffering a torn ACL during winter ball in the 2023-24 offseason.

Young, 29, is a journeyman in his first season with the Mets organization. The former Cubs and Cardinals farmhand posted huge numbers in the Korea Baseball Organization last year and has produced well in Triple-A Syracuse, but he’s hitting just .171/.227/.415 in 44 big league plate appearances. Like Mauricio, he’s swatted three homers in minimal playing time but generally struggled outside that flash of power.

Both Baty and Mauricio are in the last of their option years. Mauricio was already optioned once this season but spent fewer than 20 days in the minors and thus technically has not yet burned that final option year. Young has still has an option remaining beyond the current season.

A healthy Vientos could go a long way toward rejuvenating some of the Mets’ floundering offense — at least if he can get back to his 2024 form. The former second-round pick broke out with a .266/.322/.516 slash and 27 homers in just 111 games last year, but he’s hitting only .230/.298/.380 in 2025 — despite lowering his strikeout rate from 29.7% to 23.6%.

The Mets are also eagerly awaiting the return of left-hander Sean Manaea. The rotation suffered a pair of losses in the past two weeks, with both Kodai Senga (hamstring) and Tylor Megill (elbow) hitting the injured list. Frankie Montas returned and pitched well in his season debut this week, which helps to patch over some of that lost depth, but Manaea was arguably the Mets’ best starter down the stretch last season and is ticketed for a key role in the rotation.

Manaea has been out with an oblique strain. He was gearing up for a return and progressing through a rehab assignment when, earlier this week, imaging revealed a loose body in his elbow. President of baseball operations David Stearns downplayed concerns that it’s a serious issue. Manaea received an injection and was shut down for a couple days. MLB.com’s Anthony DiComo reports that Manaea is playing catch today — his first throwing since that injection — and remains on track to return at some point next week.

Setbacks or new injuries for any of Senga, Megill, Montas or Manaea could guide the Mets’ approach at the trade deadline, but for now it seems the expectation is that there are no catastrophic injuries among them. Megill is about 10 days into what’s expected to be an absence of four to five weeks, at least, but that’s the longest-reaching outlook.

A greater need at the deadline could rest in the outfield. Mets outfielders are among the most productive group in the majors overall, but a disproportionate amount of that production has come from scorching-hot Juan Soto and continued steady production from Brandon Nimmo in left field. Mets center fielders are batting just .240/.302/.364 as a group this season, and the resulting 88 wRC+ checks in 18th in the majors. Even that modest batting line is a bit misleading, as it includes productive small-sample output from both Nimmo and Jeff McNeil. Tyrone Taylor has received the lion’s share of center field reps in 2025 but batted just .227/.284/.333 when patrolling the position. Jose Siri, José Azocar and Luisangel Acuña have combined for 31 plate appearances in center field and hit poorly as well.

McNeil is doing fine work at the plate and even robbed Marcell Ozuna of a home run in center the other day, but he had all of 16 major league innings of experience at the position entering the season. The Mets are currently choosing between McNeil’s hot bat and Taylor’s steady glove in center on any given day, but an acquisition could change that.

SNY’s Andy Martino writes that he expects the Mets to be in the market for a center fielder over the next five weeks, speculating on the possibility of Baltimore’s Cedric Mullins and Boston’s Jarren Duran. There’s no indication the Mets have reached out to inquire on either AL East outfielder, to be clear, nor have either the Orioles or Red Sox signaled that they’re planning to operate as deadline sellers. Still, given the struggles of most of the Mets’ center fielders, it’s a natural area of focus, and those would be two logical targets among a broader base of possible trade candidates.

If two of Vientos, Baty, Mauricio and Acuña were hitting well enough to justify regular playing time, perhaps living with McNeil playing out of position in center would be more palatable. As it is, with that quartet scuffling — Acuña has already been optioned to Syracuse — there’s an argument to be made that the Mets ought to shift McNeil back to the more familiar position and explore some center field possibilities as the deadline draws nearer. There’s still plenty of time for that group of young infielders to get right at the plate, and their performance over the next month will be telling, as it’ll likely have a direct impact on the team’s goals.
