Dennis Cook was an 18th round draft pick by the Giants in 1985. He came up to the majors in 1988 and after 6 starts for the Giants he was traded to the Phillies along with Charlie Hayes and Terry Mulholland for reliever Steve Bedrosian in 1989.

Cook's career with the Phillies (including a brief return in 2001): 14-11, 89 games, 29 starts, 1 save and an ERA 3.81. He was a forgettable player on a pretty forgettable team.
Cook had a pretty long career with an opportunity to be forgotten by many fans. In addition to the Giants and Phillies, he also played for the Dodgers, Indians, White Sox, Rangers, Marlins, Mets and Angels. And he wasn't a terrible pitcher, he finished his 15-year career with a 64-46 record and 9 saves. I say any pitcher that lasts 15 years and has a winning record is pretty good. He soaked up a lot of innings in his career which is something teams need.
