On September 18, 1999, he became the one of the oldest players (age 35)
ever to debut in a major league baseball game when he pitched in the
eighth inning of a Devil Ray's game against the Texas Rangers. He
struck out Rangers' shortstop Royce Clayton on four pitches for the
final out of the inning. Ironically, Clayton made a cameo in "The
Rookie", which depicted Morris' rise to the majors, and again was
Morris' first major league strikeout victim, this time with Morris
being portrayed by Dennis Quaid. (The oldest was Diomedes Olivo who was
41 when he debuted for the Pittsburgh Pirates in 1960.)
