The Mets have designated left-hander Jose Castillo for assignment, per a club announcement. The move makes room for the addition of lefty Gregory Soto to the active roster. Soto was acquired from the Orioles on Friday.
Castillo, 29, debuted with the Padres all the way back in 2018. That rookie year saw him pitch to a 3.29 ERA with a 2.64 FIP in 38 1/3 innings of work while striking out opponents at a 34.7% clip. It was an impressive showing, but injuries and ineffectiveness limited Castillo to just three total outings in the majors over the next six seasons. He surrendered five runs on four walks while striking out three in two innings of work during those outings, though he posted decent numbers at the Triple-A level with a 4.32 ERA in 125 innings of work with a 29.1% strikeout rate during that time.
The lefty eventually resurfaced this year and has split his time between the Mets and Diamondbacks. His five outings in Arizona went quite poorly, as he surrendered eight runs on ten hits and three walks while striking out just three in 6 1/3 frames, but since joining the Mets back in May he’s looked much better with a 2.19 ERA and 2.76 FIP in 14 appearances. Castillo has already been designated for assignment and outrighted off New York’s roster once this season. He’ll now go through the waiver process again unless the Mets are able to work out a trade involving him prior to Thursday’s trade deadline. If he goes unclaimed on waivers once again, he’ll have the opportunity to either accept an outright assignment to the minor leagues from the Mets or elect free agency, at which point he would be free to sign with any of the league’s 30 clubs on a fresh contract.
Replacing Castillo on the roster is Soto who the Mets dealt a pair of prospects to Baltimore in order to acquire. The southpaw has a 3.96 ERA in 36 1/3 innings of work for the Orioles this year, with a 27.5% strikeout rate and a 3.28 FIP. A two time All-Star with the Tigers in 2021 and ’22, Soto was shipped to the Phillies prior to the 2023 season and has struggled during his time with Philadelphia and Baltimore since then, with a lackluster 4.53 ERA across the 2023 and ’24 seasons despite a tidy 3.63 FIP. The Mets will surely help that they can help him return to his prior All-Star caliber form so he can join the late-inning mix alongside closer Edwin Diaz, but even if Soto is little more than a league average middle relief arm for the club he’ll offer much-needed depth to a bullpen that has lost a half dozen relievers to the injured list already.
Well that was quick..
Easy pick up for the Mariners
He looked really good the other night against the Giants. I would love for the Cards to trade JoJo Romero for a mid-level prospect and pick this guy up as an on-the-fly replacement.
Here we go with the bullpen merry-go -round
I want to see the Dodgers pick him up just for the Mickey Steverman rant…
Castillo will get picked up and pitch lights out the remainder of the year, way better than Soto. And we’ll get the LOLMets. And then next year he’ll be DFAed a month into the season, LOL. I wish we could keep Castillo but the point is he’s too hot and cold.
Hopefully someone claims him. I don’t want to see him on the team ever again
Hope Mets are able to retain him. I’d like to have him as depth going into next season.
One thing has nothing to do with the other. He will be a free agent again at the end of the year. So the Mets can just sign him, regardless of where he plays out the rest of ’25.
