The White Sox have acquired left-hander Tyler Gilbert from the Phillies, per an announcement from Philadelphia. Chicago sent right-hander Aaron Combs back to the Phillies in exchange for Gilbert’s services. Gilbert had been designated for assignment by the Phillies prior to the holidays. The White Sox designated infielder Braden Shewmake for assignment to make room for Gilbert on their 40-man roster.
Gilbert, 31, pitched just 8 1/3 innings for the Phillies this year after signing a minor league deal with the Reds last winter and being traded to Philadelphia back in May. A sixth-round pick by the Phillies back in 2015, he was surrendered to Arizona in the minor league phase of the Rule 5 draft and made his big league debut as a Diamondback during the 2021 season. The lefty had a rather impressive rookie season, as he posted a 3.15 ERA (135 ERA+) with a 4.27 FIP in 40 innings of work for the Snakes spread between six starts and three relief appearances. The highlight of his rookie campaign (and of his career to this point) was a no-hitter in his first career MLB start, where he struck out five Padres while walking three over his nine hitless innings of work.
Unfortunately, Gilbert’s next two seasons in the desert didn’t go quite as well. He struggled to a 5.23 ERA with a 5.10 FIP in 51 2/3 innings of work between 2022 and ’23, with a paltry 17.9% strikeout rate and a penchant for allowing home runs being the main culprits of the lefty’s difficulties. Those difficulties led to Gilbert being outrighted off the club’s roster following the 2023 season, which led to him electing free agency and signing that aforementioned minor league deal in Cincinnati. After rejoining the Phillies, Gilbert posted a solid enough 3.24 ERA in 8 1/3 innings of work at the big league level and paired that with an excellent run of outings at Triple-A, where he pitched to a 2.25 ERA in 40 frames across 31 appearances for the club’s LeHigh Valley affiliate. Impressive as those minor league numbers were, however, Gilbert found himself squeezed off the club’s 40-man roster just before the holidays due to the Jesús Luzardo trade.
Now that he’s in Chicago, Gilbert could find himself in the mix for starts at the big league level in what figures to be a fairly wide-open competition for starts on the south side. Jonathan Cannon, Bryse Wilson, and Drew Thorpe all seem likely to be part of the club’s Opening Day rotation if healthy, but beyond that trio a number of possible options exist including Davis Martin, Sean Burke, Jake Eder, Ky Bush, and Nick Nastrini. If Gilbert doesn’t make the club’s rotation, it’s to imagine him providing left-handed relief depth alongside Jared Shuster and Cam Booser for the club this year.
In return for Gilbert’s services, the Phillies add a right-handed minor leaguer in Combs. The White Sox’ eighth rounder in the 2024 draft, Combs has just 7 2/3 innings of work at the minor league level under his belt but struck out an impressive 39.4% of opponents at the Single-A level in his pro debut down the stretch last year. Prior to being drafted, Combs posted a 3.24 ERA in 66 2/3 innings of work pitching in the SEC. The youngster just turned 23 last week and is hardly a sure bet to influence the club in 2025, but the impressive stuff he flashed last season could carry him through the minors fairly quickly.
In order to fit Gilbert on their roster, the White Sox part ways with Shewmake. The 27-year-old was a first-round pick by the Braves in 2019 and eventually made his big league debut with the club in 2023, though that cup of coffee lasted just two games and ended before Shewmake recorded his first big league hit. He was shipped to Chicago last winter as part of the trade that brought Aaron Bummer to Atlanta, but dealt with injuries during his first year in Chicago and was limited to just 39 games between Triple-A and the majors. Those games did not go especially well, as he posted a .152/.152/.182 slash line in ten minor league games. That’s more or less in line with what he did in the majors, as well: in 67 trips to the plate, Shewmake hit just .125/.134/.203 (-15 wRC+). The White Sox will have one week to waive or trade Shewmake, and if he clears waivers successfully they’ll have the opportunity to outright him to the minors as non-roster depth for the coming season.
