After a tough one-run loss in Yankee Stadium on July 13,C.J. Wilson said one of the keys to second-half baseball is that "you have to have a big windshield and keep looking ahead — you can't have a rear-view mirror." After Saturday night's 3-0 loss to Tampa Bay in Angel Stadium, the first-place Texas Rangers remain several car lengths ahead of the Angels, who are four games back in the American League West. But that object in the rear-view mirror is now in the windshield. The red-hot Oakland Athletics won for the 18th time in 21 games Saturday and moved into sole possession of second place in the division, 3 1/2 games behind the Rangers.
