"I just found myself a little bit mechanically," said Marquis. "I didn't think I was going to get out of the third, but I got a little boost of energy, I felt something in my delivery at the end of the third inning when I was facing the eight and nine hitters and I just rolled with it and things went smoothly from there."
Kyle Blanks added his seventh home run in the sixth off Miley with a line shot to left.
Arizona threatened in the eighth on singles by Gregorius and Montero, but Dale Thayer struck out Cody Ross and Jason Kubel looking to end the inning.
"We started out pretty good," said Montero. "Jason (Kubel) seemed pretty upset. But we couldn't get a rally going. Then he made a good pitch (to Miley) to get out of that jam in the top of the fourth. It's frustrating."
NOTES: Diamondbacks manager Kirk Gibson said he hasn't heard anything about the appeals of his players' suspensions from their fight with the Dodgers earlier this week. Arizona will likely play with a 24-man roster with pitcher Ian Kennedy being given a 10-game suspension. Gibson is confident the suspensions will be staggered, allowing the team to mix and match position players. ... Arizona 2B Aaron Hill was scheduled to make a minor league rehab start Saturday night for Triple -A Reno at Tucson. He will play Sunday, take off on Monday and play for Reno at home on Tuesday and Wednesday. Gibson was hopeful that Hill would play at least five innings. Hill has been sidelined since April 11 with a slight fracture in his left hand. ... Padres OF Carlos Quentin was out of the starting lineup because of an injured left shoulder, which he said he hurt taking a swing on Friday. ... Former Padres catcher John Baker was claimed off waivers by the Los Angeles Dodgers on Saturday and optioned to Triple-A Albuquerque. ... Clayton Richard, originally scheduled to pitch Saturday, will start Sunday. Padres manager Bud Black said he wanted to keep Marquis on regular rest and gave the struggling Richard an extra day between starts. Richard (1-5, 8.06) will be opposed by Kennedy (3-4, 5.49) who is appealing his suspension.
