The Diamondbacks are expected to call up Bratt from Triple-A Reno to start Sunday's game against the Dodgers in Los Angeles, Nick Piecoro of The Arizona Republic reports.
Bratt is poised to make his second major-league start of his career after Zac Gallen was scratched from his turn through the rotation this weekend due to right elbow inflammation. Gallen is expected to be placed on the 15-day injured list, so a strong start Sunday could earn the 23-year-old Bratt multiple turns in the Diamondbacks rotation. Bratt sports a 2.41 ERA and 0.96 WHIP across 52.1 innings in Triple-A this season (13 starts), but he's been limited to fewer than five innings in five of his last six outings. As such, Bratt could be in store for a limited workload with the big club Sunday.
