DENVER — Jorge De La Rosa's season debut went awry in a hurry.
De La Rosa, returning from a groin injury that sidelined him for the first two weeks of the season, lasted two innings and gave up a career-high tying nine runs in the Colorado Rockies' 14-3 loss Monday night to the San Diego Padres.
Rockies manager Walt Weiss said De La Rosa, activated from the disabled list before the game, was fine physically but may have let his excitement over his return get the better of him.
"He was ready," Weiss said. "He was almost too strong, if there is such a thing. His velocity was up, but pitches were up, too. It looked like everything was elevated, fastball and changeups. He was plenty ready."
Matt Kemp had three hits and four RBIs for the Padres, who scored nine of their runs in the first two innings.
Derek Norris had three of San Diego's 17 hits, Will Venable homered and Odrisamer Despaigne (2-0) got his first major league hit in addition to limiting the Rockies to two runs on six hits over 6 2-3 innings.
De La Rosa, meanwhile, didn't have his usual sharpness at Coors Field, where he has a 45-15 career mark.
"I think I was overthrowing a lot, got too excited," De La Rosa said. "I was trying to throw as hard as I can, but you can't make outs if you don't have command. It was my first start. I'll go back, be more calm next time and get better."
The first four Padres batters got hits, and Yonder Alonso's two-run single capped their best first inning since scoring five at Cincinnati on July 29, 2009.
Will Middlebrooks' two-run triple highlighted a four-run second that ended De La Rosa's night.
It was the worst outing for De La Rosa (0-1) since also giving up nine runs against the Los Angeles Dodgers on May 3, 2008.
The Rockies used six relievers to get through the game with only Friedrich pitching more than an inning.
Padres: RHP Ian Kennedy threw 81 pitches in an extended spring training game on Monday. Kennedy, who was put on the 15-day disabled list with a hamstring injury on April 10, will rejoin the team Tuesday in Denver. He is eligible to come off the DL on Saturday.
Rockies: 3B Nolan Arenado was a late scratch from the lineup with a sore left wrist. Arenado is hitting .311 and leads the team with three home runs and is tied for the team lead with 10 RBIs. The Rockies said he is day to day. ... LF Corey Dickerson left the game after grounding out to end the third inning. He has been dealing with pain from plantar fasciitis in his left foot.
The Rockies have given up 14 or more runs to the Padres 10 times in the series between NL West rivals. Nine of those have come at Coors Field, most recently on Aug. 10, 2008.
Padres: RHP Brandon Morrow (0-0) is going for his first win in his third start. He has pitched well this season, allowing just two earned runs in 14 innings, but he hasn't stuck around long enough for the win in either game.
Rockies: LHP Tyler Matzek (1-0) has a 1.80 ERA but the Padres have hit him well. In four 2014 starts against San Diego Matzek is 1-3 with a 3.67 ERA.
