   Toronto Blue Jays
2. St. Louis Cardinals
   Minnesota Twins

Bob Feller spent his entire MLB career with the Cleveland Indians and won 266 games for the club. If this wasn't impressive enough, he also had his career interrupted for four years as he joined the Navy. His wins would have been much higher had he been able to play those four years.

1. San Diego Padres
   Atlanta Braves
2. San Francisco Giants

   Washington Nationals

Despite only having 81 wins for the team, Ricky Nolasco is the all-time franchise leader for the Miami Marlins. It is rare to see a team with a wins leader that is still in the MLB, but that is a testament to how new the Marlins are and how unsuccessful most of their history has been.

1. Tampa Bay Rays
   Toronto Blue Jays
2. Milwaukee Brewers
   Los Angeles Angels
