Diekman (abdomen) expects to be pitching by the All-Star break, Stefan Stevenson of the Fort Worth Star-Telegram reports.

EDGE Analysis

Diekman underwent colon surgery in January and is scheduled to have another operation in April. The 30-year-old reliever has been with Texas for the past two seasons, posting a 3.01 ERA and a 1.09 WHIP in 92 games. Diekman's absence opens the door for Alex Claudio to get more opportunities as the only returning left-handed reliever. He compiled a 2.79 ERA and 34 strikeouts in 51.2 innings for the Rangers last season.
