These guys were bad for the Mariners. They really were, but they weren’t the worst of the worst.
Don Wakamatsu
The Hood River, Oregon native’s PNW roots didn’t exactly give him home-field advantage. He managed the M’s for all of the 2009 season and half of 2010 until enough was enough and he was fired. As the Seattle skipper, he finished 127-147 (.464). The worst thing about Wakamatsu was that he guided the Mariners to an 85-77 season in 2009, but that success didn’t follow him into 2010. He was fired on August 9. The Mariners had a record of 42-70 at the time.
