Koji Uehara: The reliever has become a staple on this stock report this month, but his splitter has made life difficult for hitters, particularly lefties.
Mike Adams: He's not feeling 100 percent with the tight muscle in his shoulder and he gave up three solo home runs Thursday to make that game a lot tighter than it should have been.
Martin Perez: The young starter couldn't make it out of the first inning Wednesday, forcing the bullpen to pick him up. Texas lost the game. Perez needs to have a short memory as he's slated to pitch Monday in Oakland.
Mark Lowe: He gave up a home run in extra innings to George Kottaras on Tuesday to give Oakland a 3-2 win. He's struggled to find consistency, and part of that is he hasn't pitched much this month. But it's unlikely he'll be on the postseason roster.
