Diamondbacks face Pirates with young starters adjusting before series

The Arizona Diamondbacks are in Pittsburgh facing the Pirates, with rookie lefties Mitch Bratt and Kohl Drake making adjustments ahead of their upcoming starts. Bratt is working on improving his four-seam fastball command after walking five batters in his last outing. Drake, meanwhile, is experimenting with a new slider grip to better compete against left-handed hitters. The Diamondbacks seek to bounce back after losing 3-2 in the previous game, a loss that has troubled manager Torey Lovullo. The series continues with a matchup featuring Diamondbacks RHP Brandon Pfaadt and Pirates RHP Bubba Chandler.
