The White Sox are one of the game’s few clear sellers with the trade deadline still six weeks out, and teams have been showing recent interest in closer Michael Kopech, reports Bruce Levine of 670 The Score. Among the interested clubs are the Royals, Phillies and Yankees, each of whom has sent scouts to watch the hard-throwing righty in the past few weeks. Levine adds that rival clubs believe the Sox seek controllable pitching in return.
Kopech, 28, is in his first season as a full-time reliever after making a combined 52 starts with the ChiSox in 2022-23. He’s taken up the role of the team’s primary closer, though given Chicago’s dismal results this season, he’s only picked up five saves on the year. Kopech’s bullpen tenure got a strong start, but he’s hit a rough patch of late, yielding eight earned runs over his past 6 1/3 frames. That rocky stretch has ballooned his ERA from 3.18 to 4.91.
Despite that lackluster mark, there’s plenty to like about Kopech. Once touted as one of the game’s elite pitching prospects — he and Yoan Moncada headlined the White Sox’ return for Chris Sale during their last rebuild — Kopech boasts a power arsenal that helps him miss bats in droves. He’s averaged a blazing 98.7 mph on his heater this season and punched out 32.3% of his opponents. Kopech’s 14.1% swinging-strike rate is well north of the league average. That power arsenal often comes with notable command issues; Kopech has walked 13.5% of his opponents in 2024 and sports an unsightly 13.6% mark dating back to 2022.
Beyond his bat-missing ability, Kopech is both affordable and controllable. He earned $3M in 2024 and would be arbitration-eligible again this winter before reaching free agency following the 2025 season. Adding Kopech for a pair of pennant chases would give any contending club a power arm with an often triple-digit heater, bat-missing slider and a newly implemented cutter that’s been a plus pitch thus far.
With regard to the interested parties, none of the three teams listed by Levine comes as a surprise. The Royals have already been canvassing the bullpen market in early June. However, their status as a division rival to the White Sox might make it tougher to complete a deal with Kansas City than with Philadelphia, New York or any of the surely yet-unnamed clubs who have interest in prying Kopech from the South Siders. The Royals rank 22nd in the majors with a 4.32 ERA from their relievers. Their bullpen’s collective 93.5 mph average fastball velocity (per Statcast) is 27th in the majors, while its 17.7% strikeout rate is the worst in MLB. Kopech would add the type of power, bat-missing repertoire the Royals lack.
The Phillies (3.55, ninth) and Yankees (3.19, third) both rank among MLB’s ten best teams in terms of bullpen earned run average. They’ve gotten there in slightly different ways, with the Phillies focusing on strikeouts (26.5%, third in MLB) while the Yankees have a below-average 21.9% strikeout rate but also possess the third-best ground-ball rate of any team (46.8%). Both teams are among the three best in baseball at limiting home runs, with the Philly bullpen sitting at 0.68 HR/9 and the Yankees narrowly trailing at 0.74 HR/9. Both clubs are luxury-tax payors in 2024, making Kopech’s relatively modest $3M salary all the more appealing.
It stands to reason that the Royals, Phillies and Yankees are just three of many clubs looking at Kopech as the trade deadline looms next month. Bullpen help is on every postseason hopeful’s deadline wishlist every summer, and Kopech is the type of power arm that any team would love to try to maximize. While velocity is up throughout the game, and triple-digit fastballs are no longer the rarities they once were, that doesn’t detract from Kopech’s impressive repertoire. The only pitchers in MLB (min. 10 innings) who throw harder on average are Oakland’s Mason Miller, Minnesota’s Jhoan Duran, Milwaukee’s Abner Uribe, Arizona’s Justin Martinez and St. Louis’ Ryan Helsley. Kopech’s bottom-line run prevention numbers may not stand out, but other teams covet the upside and feel there’s a potentially elite reliever to be unlocked with a few tweaks.
