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

Earns fourth save
PKansas City Royals
April 17, 2024
McArthur earned the save in the first game of Wednesday's doubleheader against the White Sox, allowing one hit while recording a strikeout in a scoreless ninth inning.
ANALYSIS
After allowing four runs in his first three outings this season, McArthur's rebounded with six consecutive scoreless appearances as he improves to 4-for-5 in save chances with a 3.72 ERA, 1.34 WHIP and 12:1 K:BB through his first 9.2 innings this year. While Will Smith could still see the occasional save chance against a string of left-handed batters, the 27-year-old McArthur appears to be the go-to closing option in Kansas City.

* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.
