Because of an injury to Giants starting catcher Bengie Molina, Posey was called up to the MLB for the first time on September 2, 2009. On September 11, 2009, Posey made his MLB debut, striking out in his first at bat against Hiroki Kuroda of the Los Angeles Dodgers. Posey got his first major league hit on September 19 against Jeff Weaver of the Dodgers. In 17 at-bats with the Giants in 2009, Posey had two hits.
