The Royals placed right-hander Chris Stratton on the 15-day injured list due to a right forearm flexor strain, per a team announcement. Left-hander Angel Zerpa was called up from Triple-A Omaha in the corresponding move.
Only 16 days remain in the regular season, so between the calendar and the usually serious nature nature of forearm and flexor-related injuries, it seems likely that Stratton’s 2024 campaign is over. If the strain is mild, Stratton could conceivably return to action if the Royals make a deep playoff run, but the larger concern at this point could be whether or not the 34-year-old could be facing a surgical procedure that could threaten some (or all) of his 2025 season.
Stratton has allowed five runs over his last two appearances and two innings of work, but even if his injury factored into these rough outings, the righty has already been struggling in his first season in Kansas City. Stratton has a 5.55 ERA over 58 1/3 innings, along with a 17.1% strikeout rate and 12.8% walk rate that are both far below the league average. The K% and BB% rates are both career lows for Stratton over a full MLB season, while his ERA is only a touch better than the 5.57 ERA he posted with the Angels and Pirates in 2019.
The right-hander bounced back from that tough 2019 campaign with solid results and a full-time move to relief pitching over the next four years, posting a 3.91 ERA in 255 1/3 frames with the Pirates, Cardinals and Rangers. That includes a 3.92 ERA and a career-best 7.4% walk rate in 82 2/3 innings with St. Louis and Texas last year, and four more innings in the playoffs as Stratton won a World Series ring on the Rangers’ championship squad.
That performance provided a platform for Stratton to land a two-year, $8M free-agent deal with the Royals this past winter. The deal is technically a one-year contract with a player option for 2025, as Stratton can choose to take either a $500K buyout or remain in the last year of the deal for a $4.5M salary next season. Between his subpar performance and now this injury, Stratton seems like a lock to pass on his opt-out clause.
While Stratton wasn’t delivering much in the way of results, his absence will leave K.C. short of an innings-eating bullpen arm. Zerpa’s 4.40 ERA over 47 innings could provide a bit of a boost, but Stratton joins Will Smith (back spasms) and Hunter Harvey (mid-back tightness) on the list of injured Royals relievers. In Harvey’s case, MLB.com’s Anne Rogers writes that Harvey has started throwing but the team isn’t yet sure when or if the right-hander might able to return to action.
