Brian Michael Daubach (born February 11, 1972 in Belleville, Illinois) is a free agent first baseman. He bats left-handed and throws right-handed. He has often served as a designated hitter and can also play the outfield.
Daubach was selected by the Mets in the 17th round of the 1990 amateur draft. In 1995, he crossed picket lines to be a replacement player (scab) during the MLBPA players' strike, but the strike ended before any of the replacements saw game action. He toiled for seven years in the Mets' minor league system without breaking through to the majors before being granted free agency. In 1997, he signed with the Florida Marlins organization and made his major league debut in 1998. Since then he has played for the Boston Red Sox (1999-2002, 2004) and Chicago White Sox (2003). He started 2005 with the Norfolk Tides, a Triple-A affiliate of the Mets in the International League. On June 16, 2005, he finally made his debut with the club that drafted him fifteen years earlier. He played for the Memphis Redbirds, the AAA-affiliate of the St. Louis Cardinals in 2006.
Daubach's best seasons have come with the Red Sox; he averaged 21 homers and 75 RBI per year, and gained a reputation as a "Dirt Dog" for his style of play. He later received a World Series Championship ring as a member of the 2004 Boston Red Sox. In his seven-season major league career, he has compiled a .259 batting average with 93 home runs and 333 RBI in 661 games.
Daubach is one of a select few Major League Baseball players who is not a member of the MLB Players Union because he was a strike breaker during the 1994 strike shortened season.
