By Frank Pingue HOUSTON - The Los Angeles Dodgers, playing with their backs against the wall for the first time all year, sprang back to life with a five-run ninth inning on Saturday to beat the Houston Astros 6-2 and level the World Series at two games apiece. With Dodgers ace Clayton Kershaw set to take the mound for Sunday's pivotal Game Five in Houston, the best team in baseball all season are suddenly back on track in their quest for a first World Series title since 1988. The Dodgers, who breezed through regular season and into World Series, were staring at a potential 3-1 series deficit until Cody Bellinger's bat came alive when he doubled and scored the tying run in the seventh inning.
