Mets Claim Diego Castillo From Diamondbacks

The Mets announced that they have claimed infielder Diego Castillo off waivers from the Diamondbacks. The latter club had designated him assignment two weeks ago when they made their signing of Lourdes Gurriel Jr. official. DFA limbo normally only lasts a week but the clock is paused for the week from Christmas to New Year’s. The Mets’ 40-man roster is up to 39, but it will be full once their deal with Harrison Bader is announced.

Not to be confused with the 29-year-old reliever of the same name who recently signed with the Rangers, this Castillo is a 26-year-old infielder. He was once a Yankees prospect, though that club flipped him to Pittsburgh in the Clay Holmes trade. The Pirates designated him for assignment just over a year ago and traded him to the Diamondbacks.

Between the Bucs and D’Backs, he has 284 major league plate appearances but has hit just .205/.250/.380 in those. He’s fared much better in the minors, including last year. In 556 plate appearances for Arizona’s Triple-A club in 2023, Castillo walked more than he struck out, a 17.4% walk rate compared to a 14.2% strikeout rate. He only hit three home runs but slashed .313/.431/.410 for a wRC+ of 117. He also stole 13 bases and suited up at the three infield positions to the left of first base, as well as left field.

The Mets have been focused on depth this winter, claiming Penn Murfee, Zack Short, Tyler Heineman, Cooper Hummel and now Castillo off waivers in order to bolster their depth in various places. They’ve also given out one-year deals to Bader, Luis Severino, Joey Wendle, Jorge López, Austin Adams and Michael Tonkin.

Castillo still has an option and won’t need to be guaranteed an active roster spot. He can give the club extra depth around the infield, where the Mets will have Pete Alonso, Jeff McNeil and Francisco Lindor in regular roles. The third base job is likely up for grabs, with Brett Baty, Mark Vientos and Wendle in the mix for playing time there. Castillo and Short figure to be in depth roles who can fill in at various spots throughout the year as injuries dictate.
