He played in Major League Baseball (MLB) from 1989 to 2002 for the Los Angeles Dodgers, Philadelphia Phillies, Montreal Expos, and Toronto Blue Jays.

[1] In Montreal, Fletcher became a fixture in the lineup, regularly playing in over 100 games a year, and helping the Expos to two consecutive second place finishes in the National League Eastern Division in 1992 and 1993.

Fletcher's home runs made him one of seven Blue Jays to hit 20 or more that season, helping Toronto tie a record set by the 1996 Baltimore Orioles.

After these career highs, however, Fletcher struggled through the 2001 season and played in his final major league game on July 16, 2002 at the age of 35.

Fletcher has done occasional color commentary for the Montreal Expos on The Score and the Toronto Blue Jays on Rogers Sportsnet.
