Zac Gallen struck out 11 in six stellar innings, pinch hitter Pavin Smith hit a three-run homer and the Arizona Diamondbacks ended a three-game losing streak with an 8-2 win over the San Francisco Giants. Arizona needed a rebound after a losing streak that included a blown eight-run lead in a loss to Milwaukee and Tuesday’s lackluster 11-0 loss to the Giants. The Diamondbacks responded behind a strong performance from their ace to tie the New York Mets in the NL wild card, a game ahead of Atlanta. Gallen gave up a run-scoring double to Tyler Fitzgerald in the second inning, but shut the Giants down after that.
