SAN DIEGO -- Tyson Ross extended his streak of quality starts to 14 and Cory Spangenberg shined in his Major League debut as the Padres defeated the Diamondbacks, 3-1, in the opener of a four-game series at Petco Park on Monday.
Ross allowed one run on six hits over six innings to extend his franchise-best record for consecutive quality starts. In addition, Ross has also given up six or fewer hits in each of the 14 starts. He struck out eight and walked two batters.
After cruising through the first five innings, despite taking a comebacker off the base of his glove that warranted a visit from the team trainer, Ross faltered slightly in the sixth.
Arizona strung together three consecutive singles to plate a run and put Ross's streak in serious jeopardy, but after a mound visit from manager Bud Black, the 27-year-old right-hander recovered to strike out the next three batters.
Black said he went to the mound in that situation because Ross had actually hurt his knee on the comebacker play in the fifth, and he wanted to check on his starter.
"I just kind of twisted my knee a little bit," Ross said. "It's a minor thing and Buddy came out and checked on me to make sure I was OK."
The visit actually helped Ross in another way, allowing him to settle down after the three hits and focus on limiting the damage from there.
"I was fatigued a little and had a lack of concentration," Ross said. "[Black] came out and it gave me a chance to refocus and get back to execution."
Black admired the way Ross escaped the inning despite being near 110 pitches and having a difficult first-and-third situation with no outs and a run already in.
"In a 3-1 game, in the sixth inning, he has to make pitches," Black said. "I thought that, not only was that a pretty good learning experience for him, being in a tough situation with no outs when maybe he was tiring. But, I felt at that point he was our best pitcher. His stuff was still great."
San Diego broke through against Trevor Cahill in the fourth when Alexi Amarista bounced a bases-loaded single to right for a 1-0 lead. In the next inning, Spangenberg slapped a two-run single to right for his first Major League hit.
"[Cahill] got me down 0-2, but I was just looking for a ball up in the zone a little bit that I could put the bat on, and I got a slider up and got just enough of it to find a hole," Spangenberg said.
Spangenberg also made a pair of nice defensive plays in just his eighth professional game at third base. The 23-year-old former first-round Draft pick has played primarily at second base.
"[Spangenberg] had a good day," Black said. "Two nice plays, the diving play to his left, a good play to save a run on a slow-roller. Just missed the [Mark] Trumbo ball in the sixth that tipped off his glove. I thought he had some good swings."
Nick Vincent and Dale Thayer each pitched scoreless innings before Kevin Quackenbush came on to record the save in the ninth, his second in four chances.
Cahill exited after four-plus innings, allowing three runs on five hits. He walked six and struck out five.
