[AZ Central] Luke Weaver tosses five scoreless in Diamondbacks’ shutout of Giants - Christian Walker had a productive day at the plate, driving a triple off the right field wall in the second inning and doubling down the left field line in the fourth. “He continues to be a very, very good bright spot for us on both sides of the baseball,” Diamondbacks manager Torey Lovullo said. “Defensively, he’s made huge strides, and offensively he’s got a great approach and he gets that foot down and his hands are firing for him he can drive the ball out of any part of the ballpark.
