The Royals designated Strahm for assignment Tuesday.
The veteran left-hander was a reliable high-leverage arm for Philadelphia the past few years, but he was unable to continue that success after being traded to Kansas City during the offseason. Strahm has recorded 13 holds but is 0-for-4 in save chances with a 7.32 ERA, 1.49 WHIP and 30:14 K:BB across 35.2 innings this year. His $7.5 million salary for this season likely means he'll pass through waivers unclaimed.
