San Diego – Between them, the Giants and Padres walked into Petco Park on Thursday with three wins in their past 28 games. Trying to theorize which team needed to win more made no sense. The answer was “both.” That the Giants had Madison Bumgarner on the mound added to their urgency. They had not won a game started by anyone else since June 22. No starter besides Bumgarner has won since Matt Cain on June 13.
