The Rays placed reliever Kirby Yates on the 15-day disabled list Wednesday due to a right pectoral strain. Yates apparently suffered the injury before being demoted to the minors April 14.
Yates made three appearances for Triple-A Durham following his demotion. He went 0-1 with a 10.13 ERA over those three outings. However, his first two appearances were scoreless outings before allowing three runs in two-thirds innings Sunday.
