Stubbs stays hot with HR, 2 RBIs in Rox loss

SCOTTSDALE, Ariz. -- Cody Decker's eighth-inning grand slam broke open a tight game Wednesday as the Padres defeated the Rockies, 10-3, at Salt River Fields.

The Padres scored seven runs over the seventh and eighth innings, with Cory Spangenberg breaking a tie with a two-run single in the seventh for a 5-3 lead.

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: Righty Jordan Lyles will start for the Rockies against the Royals in Surprise, Ariz., on Thursday. Veteran non-roster reliever Rafael Betancourt will continue his bid to make the Opening Day roster. Closer LaTroy Hawkins will stay at Salt River Fields at Talking Stick to throw in a Minor League game.
