LeAnn Rimes, who turned 20 at the end of last month, is now poised to launch a movie career in earnest.

The Grammy-winning country singer, who previously appeared in the film "Coyote Ugly," will star for director Rocky Lang ("Nervous Ticks") in "The Girl Who Struck Out Babe Ruth," based on a true story, according to the Hollywood Reporter.

The trade paper reports that Rimes will play a Tennessee native named Jackie Mitchell who, in 1931, became the only woman to strike out baseball legends George Herman "Babe" Ruth and Lou Gehrig back-to-back. She was then tossed out of the game for a minor technicality: She was a woman.

The producers hope to begin filming next spring, just in time for baseball season.

In the meantime, fans of Rimes -- who became a top star with the debut of her 1996 album "Blue" and won Grammys in 1997 for best new artist and best female country vocal -- can keep themselves occupied with her latest album, "Twisted Angel," due for release Oct. 1 from Curb Records.
