The Mets will break camp with infielder Brett Baty, catcher Hayden Senger and righties Max Kranick and Huascar Brazoban on the roster, president of baseball operations David Stearns announced to the team’s beat this afternoon (links via Newsday’s Tim Healey). A decision on infielder Luisangel Acuña has not yet been reached. The Mets could still bring an infielder in from outside the organization, per Healey. Senger is not on the 40-man roster, but the Mets currently have one opening.
On top of that, Stearns revealed that righty Paul Blackburn will begin the season on the injured list due to inflammation in his right knee. He won’t throw for the next seven to ten days, but the team expects that Blackburn will return at some point in April.
Injuries to Jeff McNeil, Nick Madrigal and Ronny Mauricio (still rehabbing from last year’s ACL tear) opened the door for Baty or Acuña to break camp with the Mets in 2025. Early on, Acuña seemed like the more natural fit, given his ability to back up Francisco Lindor at shortstop. However, some struggles from Acuña and an absolute monster performance from Baty during Grapefruit League play has given Baty the nod, even if he’s not a viable shortstop option and has limited experience at second base, where he’ll play to begin the season.
In 59 spring plate appearances, Baty launched four homers, six doubles and a triple — all while walking more often (13.6%) than he struck out (10.2%). He finished the spring with a Herculean .353/.441/.745 batting line and will now see regular time at second base while McNeil is on the shelf. If Baty continues to hit, the Mets will be hard-pressed to send him back down, though that’s putting the cart before the horse.
Baty, a 2019 first-rounder and longtime top prospect, has seen action in parts of three MLB seasons but has yet to put it together in the majors. He’s .215/.282/.325 hitter in 602 big league plate appearances. He also only just turned 25 this offseason, however, and Baty boasts a terrific track record in Triple-A. He’s played parts of three seasons at the top minor league level and turned in a hearty .273/.368/.531 in 94 games there. That .899 OPS is a near-mirror image of the .900 mark he logged in 129 Double-A games and the .911 mark he recorded in 51 High-A games.
Senger, 27, was the Mets’ 24th-round pick back in 2018. He’s slowly climbed the minor league ladder for several years, splitting time the past three seasons between New York’s Double-A and Triple-A affiliates. In 2024, he turned in a combined .234/.302/.363 slash between the two levels. He ranked as highly as 23rd in the Mets’ system back in 2022, with Baseball America calling him a likely backup who has better-than-average blocking and throwing skills. He’s thwarted 31% and 37% of stolen base attempts against him over the past two seasons, even as limits on throws to first base and slightly larger bases have resulted in far greater success for runners on the basepaths.
Were it not for an injury to Francisco Alvarez, Senger likely wouldn’t have been in position to earn a roster spot. Alvarez fractured the hamate bone in his left wrist during batting practice earlier in camp, however, which required surgery. He’ll miss at least a month of the season. Journeyman Luis Torrens will break camp as the Mets’ starting catcher.
The Mets acquired Blackburn from the A’s last summer, but he’s scarcely been able to pitch for the team. The 31-year-old righty (30 at the time of the swap) pitched in only five games before a comeback liner struck his right hand and sent him to the injured list. He avoided any fractures, but Blackburn required some down time due to swelling and a lack of mobility. While on the mend, he suffered a spinal fluid leak in his back. He didn’t return in 2024 and underwent surgery in October.
Blackburn is a late bloomer who clearly has the ability to pitch in a big league rotation but has repeatedly been set back by uncommon injuries. On top of the spinal issue last year, he’s also missed significant time due to a stress reaction in his right foot and a torn pulley tendon in his right middle finger. Dating back to 2022, Blackburn has a 4.43 ERA, 20.2% strikeout rate and 7.5% walk rate in 290 1/3 MLB frames.
It’s been a tough spring for the Mets’ rotation. Frankie Montas was diagnosed with a lat strain shortly after camp opened, leading to a full shutdown of six to eight weeks. Sean Manaea suffered an oblique strain not long after that. Prospect Christian Scott is still recovering from last summer’s Tommy John surgery.
The Mets will open the season with a rotation that includes Opening Day starter Clay Holmes, lefty David Peterson and righties Kodai Senga, Tylor Megill and Griffin Canning.
