According to the Elias Sports Bureau (h/t ESPN Stats & Information), he joined Hall of Famer Early Wynn (1959) as one of just two players in the modern era to hit a home run, record a complete-game shutout and strike out 14 batters in the same game.
In addition to his 14 strikeouts, the lefty allowed just three hits and a lone walk, needing 112 pitches to make it through the full nine innings in a 5-0 Giants victory.
San Francisco's batters provided a 3-0 lead by the end of the fourth inning, but it was Bumgarner who knocked in the insurance runs—first with an RBI double in the fifth inning, then with a solo home run in the seventh.
