Drew Stubbs continued his hot spring for the Rockies with a solo home run in the first inning, his second in Cactus League play. He later added an RBI single, raising his average to .333.
"I hadn't really hit too many balls to right-center or right field," Stubbs said. "Most of my hits had been to the pull side. To get that swing off [field] felt good today."
San Diego starter Tyson Ross allowed three runs with five strikeouts in 3 2/3 innings. Two of the runs he allowed came with two outs in the third inning, aided by a two-out walk and a wild pitch. He had three wild pitches in the inning.
"It was good. I got up and down four times, got to work with [catcher Wil Nieves] for a second time and just building on things and getting ready," said Ross, whose five strikeouts all came on sliders.
Colorado starter Tyler Matzek, who threw three scoreless innings his last time out against the White Sox on Friday, allowed two runs on three hits in 3 1/3 innings. He hit two batters, walked one and struck out three.
"I was just rushing a little bit, especially in that third inning," Matzek said. "I wasn't getting extension on that slider, threw it up and got hurt a couple of times. I've got to stay back and really extend on that fastball and slider."
Wil Myers and Yangervis Solarte continued their strong springs with run-scoring hits. Myers had an RBI double in the third inning Wednesday and Solarte followed with an RBI single, his 10th hit of the spring.
Carlos Quentin had two hits for the Padres.
Nolan Arenado added two hits for the Rockies.
Up next: The Padres have their only off-day of the spring Thursday before resuming Cactus League play vs. the Royals at 7:05 p.m. PT on Friday at Peoria Sports Complex, live on MLB.TV. Ian Kennedy is scheduled to start for the Padres, his fourth outing of the spring. He's 0-1 with a 9.45 ERA in 6 2/3 innings. He allowed two runs in three innings the last time out against the Indians on Sunday. He'll likely go upward of four innings this time out. Spring hasn't always been kind to Kennedy, who had a 6.33 ERA last year in Cactus League play.
