Bruce Bochy tried Madison Bumgarner and another starting pitcher, Mike Leake, as pinch hitters. San Francisco rallied back once and then again, and still fell short. Todd Frazier hit his 34th home run leading off the 10th to make up for a costly throwing error an inning earlier, and the Cincinnati Reds held on for a wild 9-8 victory against the Giants on Tuesday night that snapped San Francisco's four-game winning streak.
