Dennis Cook had a long career as a journeyman starter and then reliever in the major leagues. He pitched 15 years for nine different teams (two of which he played for twice). He was an unusually good hitter for a pitcher, with a .264 lifetime batting average. He was also unusually good in post-season play, pitching 16 1/3 innings without giving up any earned runs, and with 16 strikeouts. He played in the 1997 World Series with the Florida Marlins and the 2000 World Series with the New York Mets.

In 1988, when he went 11-9 with Phoenix in the Pacific Coast League, he had his first shot at the major leagues. The following year he was 7-4 with Phoenix. He was back in the minors for 21 games in 1991 in the Los Angeles Dodgers organization and 12 games in 1993 in the Cleveland Indians organization. Lifetime in the minors, his record was 57-40.
