It's no wonder the Rangers have won all five of Martin Perez's last five starts. The southpaw has held four of his past five opponents to two earned runs or less. The Angels have lost the past four times going against a lefty starter.

Perez goes for the Rangers here against Angels lefty Andrew Heaney, who is on the comeback trail after undergoing Tommy John surgery last year. This marks Heaney's fourth start of the season. He has been up and down, which often is the case for those pitchers in their first year back from serious elbow surgery.

The Rangers just saw Heaney on Aug. 23. They smacked three homers off him in five innings in a 7-5 victory. Texas is 18-14 versus southpaw starters this season.

Texas is short-handed in the bullpen with setup men Matt Bush and Keone Kela on the DL. But closer Alex Claudio didn't pitch Saturday and the Angels also have an unsettled bullpen without a definitive closer right now.
