Houston, TX (SportsNetwork.com) - The Houston Astros have activated pitcher Brett Oberholtzer from the 15-day disabled list to start Monday's game against the Baltimore Orioles.
Oberholtzer has been limited to just one start thus far in 2015 due to blister issues that have plagued him since spring training. The left-hander lasted just three innings in that lone outing, which took place May 13 against San Francisco.
The 25-year-old was deemed ready to return after throwing 4 2/3 innings in a rehab start for Triple-A Fresno on Wednesday.
Pitcher Michael Feliz was optioned to Double-A Corpus Christi to make room on the active roster. Feliz made just one appearance, a scoreless inning of work Sunday against the White Sox, after being promoted to the majors on Friday.
