Castro, 29 in April, just finished a strong three-year run as one of the better multi-positional players in the sport. That run ended with a deep slump just before he hit free agency but he has still secured a nice deal for himself.
He was non-tendered by the Tigers after the 2022 season and then landed with the Twins via a minor league deal ahead of the 2023 campaign. That minor league pact turned into a huge win for Minnesota. Castro cracked the Opening Day roster in 2023 and went on to have a strong season, getting into 124 games and stepping to the plate 409 times. He hit nine home runs and drew walks at an 8.3% clip. His .257/.339/.411 batting line led to a 107 wRC+, indicating he was seven percent above average at the plate overall. He also stole 33 bases in 38 attempts.
Defensively, he bounced all around the diamond, spending time in all three outfield spots and the three infield positions to the left of first base. He got strong marks almost everywhere the Twins put him. He even got a few mop-up appearances on the mound. The total package added up to 2.5 wins above replacement on the season, according to FanGraphs.
His 2024 season ended up being quite similar. He slashed .247/.331/.385 for a 106 wRC+, swiped 14 bags and played every position except for catcher and first base. His fWAR total nudged up to 2.9 in slightly more playing time.
Last year, he was on essentially the same pace through the trade deadline. He got into 86 games for the Twins, had a .245 /.335 /.407 batting line, 109 wRC+, and nine stolen bases while moving all around.
The Twins fell out of the race and pivoted to selling at the deadline. They flipped Castro to the Cubs for minor league pitchers Ryan Gallagher and Sam Armstrong. Castro’s performance plummeted after the swap. He slashed .170/.245/.240 for a wRC+ of just 40. He wasn’t helped by a .222 batting average on balls in play but the Cubs scaled back his playing time regardless. He only started two of the final 11 games of the regular season. He appeared in two playoff games for the Cubs but without getting sent to the plate.
More to come.
