HOUSTON -- With starting pitchers Brad Peacock (intercostal strain) and Brett Oberholtzer (blister) on the 15-day disabled list and rookie Asher Wojciechowski trying to iron things out at Triple-A Fresno, the Astros are still looking for some stability from the fifth spot in their rotation.
Right-hander Jake Buchanan was called up from Fresno prior to Thursday's game and will be available in long relief for a couple of days, though he could start Monday's game -- the next time that spot in the rotation comes up. Samuel Deduno is in the bullpen, but he struggled in two starts this season.
