By Frank Pingue HOUSTON - The Houston Astros escaped a thrilling home-run filled clash with a 13-12 extra-innings victory against Los Angeles Dodgers on Sunday to be one win away from their maiden World Series title. After blowing a three-run lead in the ninth inning during which they had the Dodgers down to their final strike, Houston closed out one of the wildest games in World Series history when Alex Bregman hit a walk-off single in the 10th inning. "Back and forth, the two best teams in baseball fighting to the very end and going toe to toe with each other," Bregman told reporters.
