PHOENIX - Randall Delgado tossed a three-hitter for his first career shutout, Cody Ross homered and drove in two runs and the Arizona Diamondbacks pounded out 17 hits in a 10-0 rout over the San Diego Padres on Friday night.
Arizona roughed up Eric Stults (8-9) with six runs the first three innings and had seven extra-base hits to win for the sixth time in nine home games.
Aaron Hill had a pair of run-scoring doubles before leaving with a tight right hamstring, A.J. Pollock added a two-run single and Martin Prado had two of Arizona's six doubles.
Delgado (3-3) added a pair of singles, becoming the first Arizona pitcher with a shutout and a multihit game since Randy Johnson on Sept. 14, 2003, against Colorado.
Delgado worked 5 2-3 scoreless innings his last start, a 3-1 win over San Francisco, and was even better against the Padres.
Everth Cabrera lined his first pitch of the game for a single, but the right-hander retired nine straight until Nick Hundley's leadoff double in the fourth. Delgado stranded him at second and retired 10 straight before walking Yonder Alonso with one out in the seventh.
Right fielder Gerardo Parra made a spectacular catch against the fence to rob Will Venable of a hit to end the seventh and shortstop Didi Gregorious made a diving grab for the game's final out, helping Delgado extend his scoreless streak to 14 2-3 innings.
Delgado struck out three, walked one and has allowed three earned runs or less in all eight starts this season.
Stults pitched well his previous three starts, allowing five earned runs in 21 innings, and tossed a two-hit shutout his last start against Arizona on June 14.
The Diamondbacks roughed up the left-hander right away Friday.
Hill drove in a run with a double in the first inning, then scored on Prado's run-scoring single.
In the second inning, Cliff Pennington scored from first when Hundley, San Diego's catcher, threw wildly to first on Delgado's sacrifice bunt and Hill followed with a second RBI double before leaving for precautionary reasons.
The Diamondbacks scored two runs again in the third inning, on Wil Nieves' run-scoring through a drawn-in infield and an RBI double by Pennington that made it 6-0.
Ross added a run-scoring single in the fourth inning off Stultz, who allowed seven runs -- five earned -- on 11 hits and struck out five.
Ross led off the seventh inning by hitting Colt Hynes' up-in-the-zone 0-2 pitch off the foul pole in left for his sixth homer and Pollock made it 10-0 with his two-run single.
