Cubs Get Flexibility With Willi Castro, a Lefty Bullpen Arm With Taylor Rogers

The Cubs approached the trade deadline with pitching as their top priority. They traded for Michael Soroka on Wednesday to shore up the starting rotation and added Andrew Kittredge to the bullpen later that night. That didn’t stop them from making a trade to improve their hitters: Getting in on the Twins’ Thursday fire sale, Chicago acquired utilityman Willi Castro for two pitching prospects, Ryan Gallagher and Sam Armstrong. And right before the buzzer, the Cubs also acquired left-handed reliever Taylor Rogers from the Pirates for outfield prospect Ivan Brethowr. This was the second swap Rogers was part of within a roughly 27-hour span, after he went from the Reds to the Pirates in Wednesday afternoon’s Ke’Bryan Hayes deal.
The Cubs have one of the best lineups in baseball. They lead the majors in runs scored and the National League in wRC+. So they didn’t necessarily need to upgrade their offense before the deadline. Castro’s calling card is his versatility, and that’s the primary reason they acquired him. Just this year, he’s played every position but catcher and first base. Defensively, he’s probably a little in over his head at either of the premium up-the-middle positions — his career FRV at shortstop is -3 and -2 in center field — but he’s perfectly acceptable as a second baseman (2 FRV) or in either outfield corner (5 in left, -2 in right). In previous years, he was also slightly above average at third (2 FRV) before taking a step back this season (-3), though small-sample caveats certainly apply for his defensive metrics at any specific position because of how much he’s moved around. Only once has he logged more than 500 innings at an individual position in a season, and that was back in 2021 when he played 713 2/3 innings at second base with the Tigers.
That said, he is way more than just a multi-positional backup. At the plate, Castro has been solidly above average since joining the Twins in 2023; during those first seasons in Minnesota, he posted a combined 107 wRC+ and accumulated 5.4 WAR. This season, his offensive production has been slightly better — .245/.335/.407, 109 wRC+ — than in recent years because he’s tapping into his power more. He’s already smacked 10 home runs in 344 plate appearances after hitting a career-high 12 last year across nearly 300 more trips to the plate. That he is a switch-hitter only adds to his flexibility. He has been platoon neutral for his career, but he’s hitting left-handed hurlers much better this year (131 wRC+) than he has righties (100). Castro has been worth 1.1 WAR this season, a step back from his last two years despite his offensive improvements because his defensive value has declined. Some of this is due to a dip in his defensive metrics — his only plus position this season by FRV is left field — but it also has to do with the positional adjustment, as he’s spent more innings this season at positions further down the defensive spectrum; after playing 465 2/3 innings at shortstop in 2024 and another 211 1/3 in center field, he’s logged just 26 at shortstop this year to go along with a one-inning cameo in center.
