He lost 14 games in 2008, receiving the worst run support in the league.
In 2009, Cain was named an All-Star for the first time in his career; he won 14 games and had a winning record for the first time since 2006. Cain won 13 games in 2010, but he saved his best pitching for the playoffs. He did not allow an earned run any of the three playoff games he pitched in as the Giants won their first World Series since 1954. In 2011, Cain won 12 games and had a 2.88 ERA. Cain threw the 22nd perfect game in Major League Baseball history on June 13, 2012. He had a 16–5 record during the regular season, and he finished sixth in NL Cy Young Award voting.
