Frank Daryl Tanana (born July 3, 1953 in Detroit, Michigan) is an American former left-handed pitcher in Major League Baseball. He was the California Angels' 1st round draft pick in 1971.
Tanana's major league career spanned from 1973 to 1993 and saw him playing for the Angels, Boston Red Sox, Texas Rangers, Detroit Tigers, New York Mets, and New York Yankees.
June 21, 1975 was a memorable day in Tanana's career – he struck out 17 batters in one game. In his prime, he was known for a blazing 100+ MPH fastball, which he abruptly lost when he injured his arm.

Frank is also know for having converted to Christianity midway through his career and becoming a leader in the Christian community within professional baseball.
