Luis Arraez homered in the seventh inning to break up a scoreless tie Tuesday night and five San Diego Padres pitchers combined on a three-hit shutout in a 1-0 win over the visiting Arizona Diamondbacks.

Diamondbacks starter Brandon Pfaadt entered the game with a 5.42 ERA and went eight innings for the first time in his career. The Padres scored both their runs and managed four hits against the right-hander, who had not had a quality start in any of his eight starts leading up to Wednesday.
