Sam: First game getting shut out, first series getting swept, first four-game losing streak. Falling back to 12 games over .500 and just a half-game up on the Dodgers for the first time since June 8 and June 5, respectively. An injury scare for the franchise cornerstone. That certainly gives us a lot of reasons to call it the low point!
You could make a case that the Trayce Thompson 3 HR game in Bumgarner’s first start was a lower point – after all, they were actually below .500 after that game, but it was just 1-2 in the first series of the season.
