[D’backs.com] D-backs squander bases-loaded threat in 7th - The D-backs, it seemed, had the Padres on the ropes, drawing three walks and reaching base by a hit batter in the seventh inning. Yet, somehow they failed to push across even one run in that inning as the Padres held on for a 5-4 win on Saturday night at Chase Field. The loss was the fourth straight for the D-backs, who will try to avoid being swept in this four-game series Sunday afternoon. “Just from me walking through the clubhouse and just getting the temperature of what’s going on, I think the guys are a little bit frustrated,” D-backs manager Torey Lovullo said.
