McArthur (elbow) will not return in 2024, Anne Rogers of MLB.com reports.
McArthur is being shut down after his attempts to rehab a Grade 1 UCL sprain have not gone well. The right-hander functioned as the Royals' closer for a large part of the year, racking up 18 saves in 25 chances with a 4.92 ERA, 1.45 WHIP and 49:14 K:BB over 56.2 innings. Given the nature of his injury, it's unclear if he'll be ready to go from the start next spring.
