Rookie left-hander Martin Perez continued his outstanding August for the Rangers, while Felix Hernandez, pitching in his home park in front of his yellow-clad cheering section, was the one who had the miserable afternoon for the Mariners. Perez beat Hernandez for the second time in less than two weeks in a battle of Venezuela natives, as the Rangers defeated the Mariners, 12-4, on Wednesday afternoon at Safeco Field.
