Brad Miller thought the ball would stay inside the foul pole. His manager wasn't so sure. Miller came up with the bases loaded and no outs in the fifth inning Saturday and drove Jarrod Parker's 2-1 pitch high down the right-field line. The ball stayed fair for the rookie's first grand slam. "It kept curving, but I was hoping," Miller said. "That felt good." The slam was the second of two home runs Miller hit against Oakland, and it gave Seattle a six-run lead. The Athletics mounted a comeback but the Mariners held on for a 7-5 win.
