James McArthur

27-Year-Old PitcherRP
Kansas City Royals
2024 Fantasy Outlook
The Royals acquired McArthur via trade last May after the 26-year-old was designated for assignment by Phillies. The 6-foot-7 right-hander was mostly unimpressive as a long reliever for Kansas City's Triple-A affiliate, but nonetheless he was recalled for his big-league debut last June. He allowed seven earned runs over an inning of work during his MLB debut, then was shuttled back and forth between the majors and minors multiple times. Upon his final recall in early September, McArthur looked like a completely different pitcher. He closed out the season throwing more curveballs and fewer sinkers, which resulted in a 12-game scoreless streak spanning 16.1 innings with an impressive 19:0 K:BB. He even got some run as the Royals' closer, securing four saves over the final two weeks. McArthur's strong finish certainly improves his chances of making the Royals' 2024 Opening Day roster, but closing is no guarantee. Read Past Outlooks

Falters in seventh inning
PKansas City Royals
September 10, 2024
McArthur (5-7) allowed four runs on three hits and a walk while failing to record an out versus the Yankees on Monday, taking the loss and a blown save.
ANALYSIS
Entering Monday, McArthur had allowed just one run over his previous 11.2 innings after losing the closer job in early August. He couldn't find any traction in the seventh inning Monday, with Austin Wells' three-run home run being the big hit against McArthur. The right-hander is now at a 5.01 ERA, 1.40 WHIP and 48:12 K:BB over 55.2 innings, though his ERA is 7.27 over 17.1 innings since the All-Star break.
