The Astros have optioned starting pitcher Brett Oberholtzer to Triple-A Fresno. Oberholtzer was 5-5 with a 6.11 ERA in 11 starts with Houston this season. He pitched 66.1 innings with the big club in 2016 and just 4 of his 11 starts were Quality Starts. Brett struck out 43, walked 30, posted a 1.43 WHIP and allowed a Major League-worst 15 HR.

Oberholtzer was 6-9 with a save and a 5.05 ERA in 153.1 innings in 2015 and has a career record of 24-30 with a 4.74 ERA.

To replace Oberholtzer, the Astros have recalled 25-year-old lefty Luis Cruz. Cruz had a 4-1 record and a 1.80 ERA with Fresno this season.

Cruz was 2-5 with 2 saves and a 5.40 ERA in 46.2 innings last season with Houston. In his Major League career, Cruz is 3-5 with a 5.43 ERA in 53 innings.
