Leon "Bull" Durham (born July 31, 1957) is an American former first baseman and outfielder in Major League Baseball who played for 10 seasons.

He followed that with a hot first half in 1983 of 12 homers and 55 RBI and another All-Star Game appearance, but was injured shortly after the break and missed the rest of the season.

They acquired Bob Dernier and Gary Matthews from the Phillies, moved Keith Moreland to right field, and Durham to first base.

Durham responded with another stellar year by hitting .279 with 23 homers and 96 RBIs as the Cubs won the National League East.

Mark Grace began to see more time at first, and the Cubs traded Durham to the Cincinnati Reds for Pat Perry amid rumors of drug use.

Leon Durham is widely remembered for an error that he made at first base during the 1984 National League Championship Series.

[3] In the bottom of the sixth inning, the Padres cut the Cubs' lead to 3–2 with a pair of singles by Alan Wiggins and Tony Gwynn, a walk to Steve Garvey, and sacrifice flies by Graig Nettles and Terry Kennedy.

The coincidental connection between these two events is that Durham had been moved from the outfield to first base during the 1984 season, replacing Buckner after the Cubs traded him to the Boston Red Sox for pitcher Dennis Eckersley.
