The Tampa Bay Rays claimed RHP Jay Buente off waivers from the Marlins and option him to Durham, designate RHP Rob Delaney for assignment.
Buente pitched against the Rays in Miami on Sunday, and not well. He is the only pitcher the Rays have beaten in the last six games.
Buente, 27, was designated for assignment by the Marlins on Tuesday. He was 3-0 with a 1.94 ERA at Triple-A, making five relief appearances and then five starts. He spent part of 2010 with the Marlins, making eight relief apperances. In nine big-league games he is 0-1 with a 7.07 ERA. He was a 14th round pick in 2006.
Delaney, who the Rays claimed on waivers from the Twins before the season, was not impressive during a brief stint with the Rays (13.50 ERA in three games), though he was 1-0, 2.57 in 14 games at Durham.
