Randall Delgado was good in his first seven starts for the Diamondbacks this season. On Friday he was pretty close to perfect demonstrating what good stuff and better command can do.

Delgado gave up three hits in a walk in his first career shutout and the D-backs let him enjoy it along the way by building a seven-run lead in the first four innings before taking a 10-0 victory over the Padres at Chase Field.

It was their most complete game of the season -- 17 hits sparking defense and a dominant Delgado and the crowd was on its feet and cheering as Delgado got through the ninth.

"I'm so happy right now" said Delgado who had already heard from family and friends minutes after the game.

Delgado was the runner-up in the competition for the fifth spot in the starting rotation this spring and he returned a new man when injuries and a suspension created an opening in mid-June.

Pitching coach Mike Parrott and roving pitching coordinator Mel Stottlemyre Jr. tweaked Delgado's mechanics and shortened his delivery a tad and part of the adjustment involved a mental shift. Delgado always has had good stuff and he learned a bit more about trusting it.

It is general manager Kevin Towers' mantra-- throw strikes and more times than not good things will follow. He has and they have.

Delgado has not given up more than three earned runs in his eight starts since joining the rotation June 18 and the shutout dropped his ERA to 2.85.

"When he was in spring training I think he was kind of more of a thrower" D-backs manager Kirk Gibson said.

"I think he bought into the whole gotta-throw-strikes thing. I know he went down to Triple-A and worked on his mechanics and kinda cleaning it up a little bit. His arm was a little longer his action he kind of jumped at the (hitter). He was trying to throw a little harder."

Delgado still hit 94 mph and 95 mph on the radar gun Friday but his main selling point was strike one. He threw first-pitch strikes to 21 of the 31 batters he faced and only twice got to three-ball counts. He needed only 100 pitches and 70 were strikes.
