Alek Thomas went 3 for 3 with two runs scored, Ryne Nelson struck out seven in 6 2/3 innings and the Arizona Diamondbacks snapped a four-game losing streak with a 4-2 victory over the San Francisco Giants on Monday night. One pitch after Nelson was pulled in the seventh after exceeding his pitch count, Tyler Fitzgerald sent a shot to the warning track in center — just past a diving Thomas — to score two runs and tie it at 2. The Diamondbacks answered with a run in the seventh on Geraldo Perdomo's bloop single to score Thomas.
