CineCalidad. As the 1972 baseball season draws to a close and star player Roberto Clemente prepares to knock hit number 3,000 out of the park, two brothers -- one of whom is afflicted with muscular dystrophy -- make the drive from Los Angeles to Pittsburgh in hopes of witnessing sports history in the making. Based on a true story, Chasing 3000 is directed by Gregory J. Lanesey and features Ray Liotta.
