Leon Kauffman Roberts (born January 22, 1951) is an American former corner outfielder in Major League Baseball who played from 1974 through 1984 for the Detroit Tigers, Houston Astros, Seattle Mariners, Texas Rangers, Toronto Blue Jays and Kansas City Royals.

Roberts was born in Vicksburg, Michigan, and graduated from Portage Northern High School, where he played baseball, football, basketball and ran track.

[4] With the Mariners needing a right-handed power-hitting outfielder and the Astros more speed and infield depth, he was sent to Seattle for Jimmy Sexton two years later on December 5, 1977.

[5] Roberts' most productive season came in 1978, when he led the Mariners with a .301 batting average (sixth in the American League), and set career-highs with 22 home runs and 92 RBI in 134 games.

[8] On December 18, 1980, Roberts was traded along with Willie Horton, Rick Honeycutt, Mario Mendoza and Larry Cox from the Mariners to the Texas Rangers for Richie Zisk, Jerry Don Gleaton, Rick Auerbach, Ken Clay, Brian Allard and minor-league right-handed pitcher Steve Finch in an 11-player blockbuster deal.

[6] Roberts played his last game on September 30, 1984 against the Oakland Athletics, recording a pinch-hit RBI single in his final career at bat.
