Royals right-hander James McArthur underwent surgery to repair a fractured olecranon in his right elbow and is behind schedule this spring, per Jaylon Thompson of the Kansas City Star. McArthur, who had two screws installed in his pitching elbow, is just now beginning to throw. It’s not clear exactly when McArthur had the procedure, but he ended the 2024 season on the shelf with an elbow issue. The fact that he’s even cleared for light throwing at this stage indicates the procedure took place a fair bit ago.
The 28-year-old McArthur looked like a breakout candidate late in the 2023 season. Acquired in a minor trade after being designated for assignment in Philadelphia, McArthur erupted as one of the most dominant relievers in the sport in September of 2023. An out-of-nowhere but eye-popping run of 16 1/3 shutout innings with just five hits allowed, no walks and 19 punchouts thrust McArthur into the Royals’ late-inning mix and positioned him as the team’s closer early in 2024. That brilliant finish coincided with some changes to his pitch selection; after being optioned to Triple-A in mid-August, McArthur returned in September throwing far fewer sinkers but far more sliders and curveballs.
McArthur had a rough start in 2024, yielding four runs in his first three innings before finding his groove. He pitched to a 3.35 ERA from that point through the remainder of the first half and carried an overall 3.99 earned run average into the All-Star break. His strikeout rate wasn’t close to the prior year, but McArthur was boasting elite command and a massive 57% grounder rate. He looked very much like a nice diamond-in-the-rough find by the Kansas City front office.
Perhaps that’ll still prove to be the case long term, but McArthur stumbled immediately out of the gate in the second half, serving up nine runs (eight earned) in his first three appearances. The rest of his season proved to be a struggle. McArthur pitched to a 6.87 ERA in his final 18 1/3 innings. His walk rate spiked from 4.4% in the first half to 8% in the second half. After averaging 95 mph on his sinker through the break, McArthur’s velocity began to fade. He only topped a 95 mph average on that sinker in one of his final eight appearances. His grounder rate dipped from 57% to 50%, and he didn’t pitch again after Sept. 16.
The season-ending IL placement and subsequent offseason surgery rather emphatically prove that McArthur was pitching at less than 100% down the stretch. The hope for the Royals, clearly, will be that McArthur’s late downturn was a symptom of his elbow troubles. From the point of that repertoire change in late ’23 through the All-Star break in ’24, McArthur totaled 54 2/3 innings with a 2.80 ERA, 23% strikeout rate, 3.3% walk rate and 54.9% grounder rate. If he can come even close to those levels again, he’ll be a vital part of the Royals’ late-inning attack not only in 2025 but for several years to come. McArthur is under club control through 2029 and won’t be arbitration-eligible until the 2025-26 offseason, when he’ll be a Super Two player.
For now, the Royals’ bullpen will be headlined by free agent signing Carlos Estevez and 2024 deadline acquisitions Lucas Erceg and Hunter Harvey. That’s a formidable high-leverage trio in its own right, and the September-through-July version of McArthur would only further strengthen the group for second-year skipper Matt Quatraro.
Also worth noting, per Thompson, is that righty Alec Marsh is a bit behind schedule after battling some shoulder tightness during his offseason program. He’s seemingly past that issue now, as he’s progressed into a throwing program, but he’s not quite where he would be with a normal offseason. Health permitting, Marsh would be a part of a competition for the fifth rotation spot behind Cole Ragans, Seth Lugo, Michael Wacha and Michael Lorenzen. Marsh, Kris Bubic and Kyle Wright are presumably all in that mix. Bubic arguably should’ve been considered the favorite even before this news, but Marsh’s delay in facing hitters (while Wright hasn’t pitched since 2023 due to shoulder surgery) only strengthen Bubic’s case.
Well it was either he’s recovering or he died from it. Not too many possibilities
Do the announcers say “Book him, Danno!” when he gets a strikeout?
Some of us are old enough to remember.
No they were calling him The General when he was good but it didnt last long
Yet more crappy writing from Adams. “The hope for the Royals, clearly, will be that McArthur’s late downturn was a symptom of his elbow troubles.” This sentence is a disaster. “Clearly” belongs at the start. There is no good reason to chop up the flow and syntax like this, if “clearly” is even necessary, which it probably isn’t.
Get rid of Adams already. His writing is painful.
