Two left-handers with something to prove go head-to-head Sunday afternoon, when the New York Mets and the host San Francisco Giants complete their deadlocked season series. The Mets erased the sting of walk-off defeats the previous two nights with a powerful offensive display in an 11-4 shellacking of the Giants on Saturday afternoon to even the season series at 3-3. The two hot teams, who had come into the series on four- (Mets) and five-game (Giants) winning streaks, combined for 15 runs and 26 hits Saturday after totaling just six runs and 31 hits across 26 frames in extra-inning affairs the previous two nights.
