Jake Diekman surrendered four runs (two earned) over two-thirds of an inning Friday against the Indians.
Diekman should have gotten out of the inning, but shortstop Michael De Leon botched a potential double-play grounder, setting the stage for a go-ahead three-run homer by Jason Kipnis. Jose Ramirez followed with a single and eventually came around to score after Diekman was removed from the game. The Rangers’ closer role is wide open this spring, with Diekman being considered along with a host of candidates. Alex Claudio saw the majority of chances down the stretch last year, but Keone Kela (who threw a scoreless inning on Friday) remains a threat and the club could reportedly give Tim Lincecum a chance once his deal becomes official.

Jake Diekman (colon) threw live BP and took pitchers fielding practice on Saturday.

Diekman should now be cleared to head out on a minor league rehab assignment, though Rangers pitching coach Doug Brocail cautioned that it might be a while before we see the left-hander on a major league mound. "I’m not going to put a timeline on it," said Brocail. "This is his spring training. At some point I need that arm to get tired. I think he’s starting to have that tired phase." Diekman has been out all season following three different surgeries to rebuild his colon.

Jake Diekman (colon) threw from 110 feet out on Wednesday.

He has undergone three surgeries to remove and rebuild his colon, the most recent of which came on June 9. While he is making progress and could potentially rejoin the Rangers at some point in the second half, Diekman remains a ways off from returning.

This past season, Diekman pitched to a 3.40 ERA, 1.17 WHIP and 59/26 K/BB ratio across 53 frames.
