Martin was promoted to the Dodgers on May 5, 2006, after a wrist injury to starting catcher Dioner Navarro. He got two hits, including a double, in the game. His first hit was against Chris Capuano. On May 7, he hit his first major league home run against Milwaukee Brewers pitcher Dave Bush. On June 6, 2006, Martin and Éric Gagné made baseball history by becoming the first French Canadian battery in the majors. Martin's play was good enough that, on June 26, 2006, Navarro was traded to the Tampa Bay Devil Rays. On August 13, 2006, Martin hit his first career walk-off home run in a victory that completed a sweep of the rival San Francisco Giants. On September 18, 2006, Martin hit a solo home run off of Trevor Hoffman, the third of four consecutive home runs in the bottom of the 9th inning to tie the San Diego Padres. It was the first time four home runs had been hit in a row since the 1964 Minnesota Twins.
