For VCU pitcher Robbie Andrews, changing his delivery 25 percent has made a 100 percent difference in how he feels. The rising senior appeared in 17 games for the Rams last year, finishing with a 5.56 ERA.

Changing from a sidearm delivery to a three-quarters one, he’s mowing down opponents in the Coastal Plain League, where he’s the closer for the No. 1 summer-league team in America, the Forest City (N.C.) Owls.
