It didn't take long for Michael Kirkman to call the past three days the biggest in his major league career. "Yeah, absolutely," Kirkman said. Kirkman came through for the second time in three days, protecting a one-run lead late and helping secure the Texas Rangers' 2-1 victory Saturday over the Toronto Blue Jays. The Rangers won for the second time in six games, and maintained a five-game lead in the American League West over Oakland, which beat Cleveland 8-5 Saturday.
