PHOENIX -- — Brandon Pfaadt pitched seven scoreless innings, Geraldo Perdomo had two RBI and the Arizona Diamondbacks beat the St. Louis Cardinals 7-3 on Friday night.

Pfaadt (10-6) allowed four hits with six strikeouts and no walks in his second straight sterling start. Adrian Del Castillo had three hits, an RBI and scored twice against Andre Pallante (5-6) after being called up from Triple-A Reno.

St. Louis scored three runs off John Curtiss in the ninth, on Victor Scott II's two-run homer and Pedro Pagés' run-scoring single. The Cardinals have lost four of six.

Pfaadt tossed a career-high eight innings against San Diego in his last start before the All-Star break, allowing two runs on four hits.

The right-hander allowed two hits through the first six innings before the Cardinals got two on in the seventh. Pfaadt struck out Jordan Walker and got Pagés on a weak fly to center to end the inning.
