Mark Alan Lemke (born August 13, 1965) is an American former Major League Baseball player and current broadcaster.

He made his major league debut on September 17, 1988, when the Braves called him up from AAA when the roster expanded to 40 players.

In 1988, Lemke won the Hank Aaron Award as the top offensive player in the Braves' minor league system.

While trying to turn a double play in a game against the Chicago White Sox on May 19, 1998, Lemke was injured in a collision with baserunner Chad Kreuter.

When naming the character, creators Mike and Matt Chapman recalled a gaffe by friend James Huggins: imitating a local commercial that mentioned Lemke, Huggins imaginatively referred to the baseballer as the "home star runner" for the Braves as he could not recall the position Lemke played.
