The Tampa Bay Rays have designated right-handed pitcher Jumbo Diaz for assignment following Sunday afternoon’s game against the Los Angeles Angels. The move clears room on the 25-man roster for the team to call-up right-handed pitcher Andrew Kittredge from Triple-A Durham.
Diaz suffered his fourth loss of the season on Sunday, allowing the go-ahead run to the Angels in the bottom of the eighth inning. Giving up the run and recording just a single out, his ERA rose to 5.70 on the season in his 31 appearances out of relief.
The Rays first acquired Diaz off waivers from the Cincinnati Reds back in March. He had spent the past three years as a member of the Reds bullpen corps, striking out better than a batter per inning while with the team, owning a 3.65 ERA in 142 appearances.
Coming up in his place is right-hander Andrew Kittredge, who will be making his major league debut when he appears for the Rays. This season at Triple-A, the 27-year-old owns a 5-1 record with a 1.90 ERA and 1.077 WHIP. Across 52 innings of work, he has struck out 54 batters and allowed just two home runs.
Tampa Bay acquired Kittredge back in Nov. 2016 in the deal that saw Taylor Motter and Richie Shaffer heading back in the other direction.
He was selected in the 45th round by the Mariners in the 2008 MLB Amateur Draft out of Spokane, Washington. Over the course of seven minor league seasons, he owns a 21-13 record with a 4.15 ERA, having recorded 18 saves and working primarily out of relief.
