The winningest regular season team of all time, the 2001 Mariners racked up an incredible 116 wins over 162 games. Since Showdown squads are entirely based on regular season performances, this team is understandably a really good Showdown team... which is surprising, since they just came off losing superstars Ken Griffey Jr and Alex Rodriguez. However, the arrival of AL MVP and ROY Ichiro injected a real spark in the team, which got career seasons out of players like Bret Boone and rode deep pitching and a well-rounded lineup to their hefty win total.
