The Royals have acquired infielder Diego Castillo from the Mets, according to his transactions tracker at MLB.com. He has been assigned to Triple-A Omaha. The log doesn’t specify what the Mets are receiving in return but it seems likely to be a cash deal.
Castillo is a 27-year-old infielder and not to be confused with the 31-year-old pitcher of the same name, who is in the Rockies’ system on a minor league deal. The infielder signed a minor league deal with the Mets in the offseason and has appeared in 13 Triple-A games so far this season. He has a rough .167/.217/.262 line, though it’s a tiny sample of 46 plate appearances and he has been held back by a .188 batting average in balls in play.
That performance probably didn’t help his standing with the Mets. Additionally, the club’s infield picture is far stronger than it was to start the year. Jeff McNeil started the season on the injured list but has been back for a few weeks now. Brett Baty has been heating up after a cold start. Luisangel Acuña is performing well enough as a bench piece. Ronny Mauricio is also back on the field and playing minor league games after missing 2024 due to a torn ACL.
For the Royals, both Michael Massey and Jonathan India are having rough years, so the second base production hasn’t been great. The Royals have received a collective .217/.251/.280 line from the keystone this year, with Massey taking most of the playing time. That results in a wRC+ of 44, which puts the Royals ahead of just the Rockies in terms of offensive production from that position. They just recalled Nick Loftin as the corresponding move for outfielder Hunter Renfroe being designated for assignment, so Castillo will perhaps take up Loftin’s spot on the Omaha roster.
Though Castillo is out to a slow start this year, his minor league track record is solid. From the start of 2021 to the present, he has stepped to the plate 1,663 times on the farm with a 13.3% walk rate, 14.9% strikeout rate, .278/.377/.418 line and 108 wRC+. Defensively, he has spent time at all four infield spots and the outfield corners. His major league batting line is only .208/.257/.383, but that’s in a fairly small sample size of 292 plate appearances, most of which came with the 2022 Pirates.
