Rusty Staub (Le Grande Orange) was an original Montreal Expo and had such great popularity over those three seasons he played there (though he did come back for a cup of coffee late in his career) that the team retired his number.  Staub would be an All-Star those three years and would put up an On Base Percentage over .400 as an Expo.

A three-pitch Pitcher, Jordan Zimmermann spent the first seven seasons of his career with the Washington Nationals.  As a Nat, Zimmermann would be named a National League All-Star twice and led the league in Wins in the 2013 season.  Overall with Washington, Zmmerman posted a 70-50 Record with 903 Strikeouts.

Prior to becoming a superstar and MVP in Colorado, Larry Walker was a very good player with the Montreal Expos who would become the only Canadian to win the franchise’s MVP award.  Walker would make an All-Star Game, and win two Gold Gloves and one Silver Slugger as an Expo.  

Following the 1994 season which was shut down due to a lockout, the Expos held a firesale, with Walker being traded to Colorado.  With Montreal, Walker had 99 Home Runs with 666 Hits, and in 2019, he was inducted into the Baseball Hall of Fame.

Pedro Martinez would become a Baseball Hall of Fame inductee, predominantly based on his work with the Boston Red Sox.  Still, it was with the Montreal Expos where Pedro would assert his stardom.
