After graduating, he was selected with the tenth overall pick in the 2007 MLB draft by the San Francisco Giants. He and Buster Posey both made their major league debuts in 2009 and established a reputation as one of the best batteries in recent MLB history. Bumgarner pitched eight scoreless innings in Game 4 of the 2010 World Series, helping win the franchise's first World Series in San Francisco and the first since 1954. Two years later, Bumgarner pitched seven more scoreless innings in Game 2 of the 2012 World Series. In 2014, Bumgarner started the Wild Card game for the Giants, throwing a shutout against the Pittsburgh Pirates. He set the World Series record for the lowest earned run average (ERA) in 2014, taking home the Most Valuable Player award as the Giants won their third World Series during his time in San Francisco.
In 2015 and 2016, Bumgarner reached his third and fourth All-Star Games, though the 2015 is the only one he pitched in during his time with the Giants. He won 18 games (his career-high) in 2014 and 2015, and he had a 15–9 record in 2016, along with a career-high 251 strikeouts. Bumgarner started his second Wild Card game against the New York Mets, again throwing a shutout.
