San Diego pitcher Tyson Ross, making his Cactus League debut, allowed two unearned runs on two hits in one-plus inning of work. He walked two and had one strikeout and reached 45 pitches three batters into the second inning.
He walked the first two batters he faced, but didn't allow a run in that first inning.
"It's a situation I'm going to find myself in during the regular season with runners on, trying to prevent a run from scoring," Ross said. "I had to do it in the first outing, but it's something that's going to come up during the season."
Colorado pitcher Tyler Matzek didn't fare nearly as well.
Matzek allowed four earned runs on five hits with two walks and one strikeout in 1 2/3 innings. Matzek threw 42 pitches, including 18 strikes.
"I was just a little amped up, which was leading to me rushing," said Matzek, coming off a rookie year that saw him go 6-11 with a 4.05 ERA in 20 games, but 4-2, 1.55 in his final six starts. "Do that, your timing's off."
Matzek said he began to feel what was wrong in his second inning, and he'll work on correcting it.
Gray, rated as the 16th-best prospect in baseball by MLB.com, was impressive in relief for the Rockies, striking out three in two scoreless innings, allowing one hit.
Hundley had one hit on Sunday. He played for the Padres from 2008 to last season when he was traded to the Orioles. He signed a free-agent deal with the Rockies in the offseason.
Up Next: The Padres hit the road for a Cactus League game in Mesa against the Cubs at 1:05 p.m. (PT) on Monday. Andrew Cashner will get his second start of the spring and is expected to work two innings. He tossed a scoreless inning on Wednesday against the Mariners. This will be a reunion of sorts for Cashner, who was drafted by the Cubs in 2008 before he was traded to the Padres in January of 2012. Look for Cashner to continue to use his fastball-changeup mix in this short stint against his former team.
