Dustin Pedroia rounded first base and pumped his fist. Seattle starter Jason Vargas stood on the mound with both hands on his head in disbelief. Pedroia's eighth-inning solo homer off Vargas tied the game at 1, and his 10th-inning single set up David Ortiz's sacrifice fly to win it in Boston's 2-1 victory over the Seattle Mariners on Sunday.
