The White Sox are planning to promote top pitching prospect Drew Thorpe to the majors on Tuesday, manager Pedro Grifol told reporters (including James Fegan of SoxMachine). The right-hander will make his MLB debut against the Mariners in Seattle.
Thorpe, 23, was the headliner of a four player package the White Sox received from the Padres in the deal that sent ace righty Dylan Cease to San Diego back in March. It was the second time Thorpe had been traded that offseason, as the Padres acquired Thorpe from the Yankees as part of the Juan Soto package back in December. As one might expect from a prospect that was part of the return for two superstars in separate blockbusters during the same offseason, Thorpe is a consensus top-100 prospect in the sport. The righty currently ranks #41 at Baseball America and #54 at MLB Pipeline.
Prospect evaluation services universally praise Thorpe’s excellent command, ability to eat innings, and the devastating changeup that he complements with a 92-94 mph fastball that’s generally regarded as average and a average-or-better slider that sits in the mid-80s. Aside from his three main pitches, BA also notes that Thorpe mixes in a high-80s cutter and a low-80s curveball. That arsenal allowed the 2022 second-rounder to tear through the lower minors during his first taste of professional ball with the Yankees last year. Thorpe dominated to the tune of a 2.81 ERA with a 32.4% strikeout rate in 18 starts at High-A last year before earning a late season promotion to Double-A.
Thorpe’s star really began to rise with that promotion. The then-22-year-old impressed with a sparkling 1.48 ERA across five starts. The righty racked up a whopping 44 strikeouts in just 30 1/3 innings of work while walking just five. Punching out 40% of batters faced while walking just 4.5% in your first taste of Double-A action is a surefire way to get plenty of attention, and so it’s hardly a surprise that both the Padres and White Sox front offices coveted Thorpe enough to make him a key piece of the trade returns for their star players.
Upon joining the White Sox organization, the right-hander returned to Double-A for the start of the 2024 campaign and has continued to dominate hitters at the level, with similar surface-level numbers in 11 starts this season to his five-start taste of Double-A last year. Thorpe has pitched to a 1.35 ERA in 60 innings of work this year, though his strikeout rate has dipped to a more pedestrian 25% this year while his walk rate has crept up to 7.6%. Even with those diminished peripherals, however, Thorpe has more than proved himself capable at the Double-A level and figured to be in line for a promotion in the near future.
What’s surprising, then, isn’t so much the promotion but that he will skip Triple-A entirely and jump directly into big league action. The White Sox optioned right-hander Nick Nastrini to the minors earlier today, leaving them with just a vacancy in a starting rotation that lost Mike Clevinger to the injured list and now features only Garrett Crochet, Erick Fedde, Chris Flexen, and Jonathan Cannon. Rather than call up a veteran at the Triple-A level such as Chad Kuhl or Touki Toussaint to fill out the rotation, the White Sox will instead turn to Thorpe in a bold move to get the righty a taste of big league action.
It’s a decision that could come with financial implications for Thorpe, as he’ll be in a good position to earn a fourth arbitration year as a Super Two player if he remains with the big league club going forward without returning to the minor leagues. Thorpe could theoretically earn himself a full season of service time by finishing in the top 2 in AL Rookie of the Year voting this season, although that would be quite the feat given the massive head starts afforded to players like Luis Gil of the Yankees and Mason Miller of the A’s who have been dominating in the majors all season.
