Tampa Bay has promoted right-handers Rob Delaney and Jay Buente from Triple-A Durham and sent down left-hander Cesar Ramos to the Bulls. After Buente made his Rays debut Tuesday, he went back to Durham.
The Rays had to add Delaney to the 40-man roster. Delaney, who was with the Rays in May before being outrighted to Durham, had a 1.78 ERA and gave up 37 hits in 50 2/3 innings with the Bull.
Buente, plucked off waivers from the Marlins in May, had a 6.67 in 27 innings at Durham. Ramos had a 4.22 ERA in 46 games with the Rays.
