David Lee Wells (born May 20, 1963 in Torrance, California) is a former Major League Baseball starting pitcher. Nicknamed "Boomer," Wells was considered to be one of the game's better left-handed pitchers, especially during his years with the New York Yankees and the Toronto Blue Jays. He is one of 20 pitchers to have pitched a perfect game in Major League Baseball. He is tied only with Kenny Lofton for appearing in the post-season with six different teams. Wells was a broadcaster on TBS Sunday baseball broadcasts during 2009.
Wells grew up in the San Diego neighborhood of Ocean Beach and attended local public schools. He graduated from Point Loma High School in 1982. He was a self-described "gym rat" who spent most of his time at the Ocean Beach Recreation Center and Robb Field. Baseball facilities at both Point Loma High School and Dana Middle School are named for him. He lives in San Diego with his wife and two sons.
Wells was a journeyman starter for the first eight seasons of his career. He debuted for the Toronto Blue Jays in 1987 as a reliever and did not secure a job as a full-time starter until he was 30 years old, despite pitching well most of the time and helping the Blue Jays win a World Series. He was released by the Blue Jays during spring training in 1993 and was signed by the Tigers almost immediately.
