The Rays have designated righty Preston Guilmet for assignment, Roger Mooney of the Tampa Tribune reports on Twitter. In corresponding moves, the team has activated John Jaso and added Steven Souza to the DL.
Guilmet, 27, threw 5 1/3 frames for Tampa Bay this year, allowing three earned runs and striking out five batters while issuing two walks. This marks the third straight season in which he’s thrown at least a handful of innings. All said, Guilmet owns a 6.43 ERA in 21 innings with 7.7 K/9 vs. 3.0 BB/9. But he’s been much better (2.47 ERA, 9.8 K/9, 2.1 BB/9) in his time at the Triple-A level.
