By Rory Carroll LOS ANGELES - Corey Seager's sixth inning sacrifice fly helped the Los Angeles Dodgers eke out a come-from-behind 3-1 Game Six victory over the Houston Astros on Tuesday to force a World Series decider. Seager's deep fly ball to right field allowed Chase Utley to scamper home for the go-ahead run, igniting the sold-out crowd of 54,128 as the Dodgers tied the series up at 3-3 to set up Wednesday's winner-take-all showdown.
