Mariners: 5 worst managers in team history

2. Bill Plummer: 1992 – Record: 64-98 (.395)
One beautiful year. That was all Plummer got. With a team boasting Randy Johnson, Dave Valle, Tino Martinez, Edgar Martinez, and Ken Griffey Jr. he somehow managed to win just 64 games. With 3 losing streaks of 7 games or more (one being 14), there was just no way the Mariners could keep him around. Plummer’s time in Seattle wasn’t all bad, though. His failures in 1992 led Seattle to the #1 pick in 1993, where they selected a shortstop named Alex Emmanuel Rodriguez. For that reason alone, I almost didn’t put him all the at second-worst of all time. That said, he was miserable as a manager, and that can’t be overlooked. Yet somehow, the Mariners had a manager worse than him. A lot worse actually. Click over for the worst manager in Mariners’ history.
