Diamondbacks prospect Jordan Lawlar to have MRI for hamstring

Arizona Diamondbacks top prospect Jordan Lawlar is scheduled to undergo an MRI on Monday morning for left hamstring discomfort, according to farm director Shaun Larkin. Lawlar felt the issue while rounding the bases for a game-tying triple in the ninth inning Saturday night while playing for Triple-A Reno. Nick Piecoro of the Arizona Republic first reported the scheduled MRI. Saturday was only Lawlar's fourth game back in Reno off the minor league 60-day injured list (thumb surgery).
