A.J. Burnett doesn't lead the major leagues in strikeouts. He just wants to and is awful close. "I'm trying to keep up with Yu Darvish, but he's pretty filthy," the Pittsburgh Pirates' ace said of the Texas Rangers' right-hander. Burnett allowed one run and struck out nine in seven shutout innings, and call-up Jordy Mercer hit a tiebreaking home run to lead the Pirates to a 3-1 victory over the Washington Nationals on Friday night.
