Mark Langston (born August 20, 1960 in San Diego, California) is an American left-handed former Major League Baseball pitcher for the Seattle Mariners (1984-89), Montreal Expos (1989), California and Anaheim Angels (1990-97), San Diego Padres (1998) and Cleveland Indians (1999).
In 1989, Langston was in a trade which sent him to Montreal and Randy Johnson to the Mariners.
Langston compiled a career 179-158 record with 2464 strikeouts and a 3.97 ERA in 2962.2 innings.
In 2005, his first year of eligibility, Langston received less than 5f the vote (he received no votes; the threshold was 26) from the Baseball Writers Association of America (BBWAA) for induction into the Baseball Hall of Fame, thus becoming ineligible to appear on future BBWAA ballots. However, he may eventually be considered for induction into the Hall by the Veterans Committee once 20 years have passed from his date of retirement (therefore, in the year 2020), in accordance with current Hall of Fame rules (enacted in 2001).
