The Twins announced a flurry of roster moves this afternoon as they selected the contracts of right-hander Diego Castillo and utility hitter Michael Helman to the big league roster. The club also placed outfielder Manuel Margot on the 10-day IL and activated infielder Brooks Lee from the 10-day IL. To make room for Castillo and Helman on the 40-man roster, left-hander Caleb Boushley was designated for assignment while right-hander Chris Paddack was transferred to the 60-day IL.
Castillo returns to the Twins for his second stint in the majors this year. The 30-year-old righty signed with Minnesota on a minor league deal over the offseason and was selected to the roster at the end of May. He ultimately made just five appearances for the club before being designated for assignment despite a solid 2.57 ERA thanks to worrying peripherals, highlighted by a 10% strikeout rate and an eye-popping 23.3% walk rate. Castillo elected free agency but returned to the Twins on a fresh minor league deal shortly thereafter, and since then has been pitching for the club’s Triple-A affiliate in St. Paul.
Even so, the results have not been good. While his numbers at Triple-A have been skewed by a disastrous performance where he surrendered five runs while recording just one out last month, he’s still posted a 4.00 ERA with nearly as many walks (6) as strikeouts (7) in nine innings of work since then. While Castillo was among the more reliable late-inning arms in the game from 2018 to 2022 with a 3.12 ERA and 3.69 FIP over that time, it seems extremely unlikely that he’ll be able to recapture that form down the stretch with Minnesota. That being said, his presence on the roster should allow the club to keep its key relief arms like Jhoan Duran and Griffin Jax fresher down the stretch by soaking up lower-leverage innings.
As for Helman, the Twins’ eleventh-round pick in the 2018 draft has steadily worked his way through the minor leagues through his career before starting the season at Triple-A this year and delivering strong results. The 28-year-old has slashed .283/.367/.508 with 13 homers, 15 doubles, and ten steals in just 63 games this year at the level, and he’s done that while splitting time between shortstop, center field, second base, third base, and left field. The versatile defender figures to offer the Twins an interesting combination of power and speed off the bench for the stretch run, and his ability to play all over the field will surely come in handy as the club navigates injuries and rest for its regular players.
Also returning to the majors is Lee, the club’s 23-year-old top prospect who struggled to a somewhat lackluster .253/.309/.333 slash line in 110 trips to the plate at the big league level before going on the IL in early August. Now that he’s back in the majors, Lee figures to feature prominently in the club’s infield mix, though with Royce Lewis locking down third base and Willi Castro performing admirably in place of Carlos Correa at shortstop, it’s not clear whether or not Lee will be able to get regular reps as the Twins look to preserve their 3.5-game lead over the Red Sox for the final AL Wild Card spot.
As for the players moving off the roster to accommodate these additions, Margot’s placement on the IL is hardly a surprise after he suffered an apparent groin strain during last night’s game. After the game, manager Rocco Baldelli told reporters (including Do-Hyoung Park of MLB.com) that the outfielder was “not moving well” due to the issue and would need to undergo an MRI. The results of that MRI are not yet clear, but they evidently warranted a trip to the IL for the 29-year-old outfielder, who has slashed just .250/.302/.350 in 116 games with the club this year.
Meanwhile, Paddack’s placement on the 60-day IL isn’t necessarily a surprise given the fact that he’s already been on the shelf since mid-July due to a forearm strain. A regular season return has long seemed unlikely for the right-hander, but it’s still possible he could return to action at some point in the postseason depending on how far the Twins make it this season. As for Boushley, the lefty has appeared in just two games for the Twins this year after signing a minor league deal with the club over the offseason, pitching to a 4.50 ERA in four innings of work.
