Michael Robert Lamb (born August 9, 1975 in West Covina, California) is a Major League Baseball infielder for the New York Mets organization.
Lamb made his Major League Baseball debut on April 23, 2000, for the Texas Rangers. He played for the Rangers until February 5, 2004, when he was traded to the New York Yankees for minor leaguer Jose Garcia. Before playing a game for the Yankees, the Houston Astros acquired Lamb from the Yankees for minor leaguer Juan DeLeon on March 25, 2004. In 2005, he saw more playing time due to regular first baseman Jeff Bagwell's injury. In 2005, he batted .233 with 10 home runs and 50 RBI, with 1 stolen base. He participated in the 2005 World Series where he hit the first World Series home run in Astros history, becoming only the second player whose last name is a type of animal to homer in the World Series (the first was Tim Salmon in 2002).
On December 14, 2007, Lamb signed a two-year deal with the Minnesota Twins. On August 25, 2008, he was designated for assignment to make room on the roster for Eddie Guardado. He was released on September 4, and then signed with the Milwaukee Brewers the following day.
