Mark was drafted by the Baltimore Orioles in the fourth round of the 1983 draft from Ramapo College of New Jersey. He made his major league debut for the New York Yankees on July 24th 1990 pitching 1 1/3 innings giving up 1 hit and 1 walk with no k's or allowing any runs. Mark was the definition of a journeyman who played for many teams throughout his professional career. He has played for the New York Yankees, Detroit Tigers, California Angels, San Francisco Giants, Montreal Expos, Philadelphia Phillies, Seattle Mariners and the Milwaukee Brewers. Definitely not as strong a pitcher as his brother Al, he did however, enjoy an 11 year career in the big leagues, finishing his career with a 65-73 record and a 4.57 ERA. Mark had the dubious honor of leading the National League in losses in 1997 with 17.
