SAN DIEGO (AP) - Heath Bell took the blame for the San Diego Padres' 5-3 loss to the Colorado Rockies on Wednesday.

Troy Tulowitzki hit a two-run double off Bell with one out in the ninth inning and the Rockies beat the Padres 5-3 to take two of three in the series.

Tulowitzki had been 0 for 14 lifetime against Bell (2-2), a two-time All-Star, before his hit to right-center. He finished with three hits and three RBIs.

``It was a bad selection and Tulo's a really good hitter,' Bell said. ``We've had some good battles together. Looking back, I think I should have thrown a breaking ball right there. I shouldn't have thrown a fastball. I made a mistake and he capitalized on it, so that's the reason we lost.

``It's really heartbreaking because I made a mistake and we lost the game,' Bell said. ``Guys were plugging along and scoring runs here and there and we fought back and I kind of blew it in the ninth.'

Colorado's Todd Helton had his first four-hit game of the season and fell a triple shy of the cycle. He scored three runs.

Padres starter Dustin Moseley was injured while batting in the fifth. He popped up, immediately grabbed his left shoulder and fell to the ground. He was helped to the dugout and reliever Cory Luebke started the sixth.

Carlos Gonzalez started the winning rally with a single to center and was sacrificed to second by pinch-hitter Jonathan Herrera. Helton was intentionally walked and the runners advanced on Bell's wild pitch while Tulowitzki was batting.

Matt Lindstrom (1-1) pitched the eighth for the win and Huston Street pitched a perfect ninth for his 17th save in 19 chances.

Aaron Cook made his season debut for the Rockies after being activated from the 60-day disabled list. He allowed three runs and six hits in 5 2-3 innings while striking out four and walking four.

Cook broke his right index finger during spring training. He hadn't pitched in the big leagues since Sept. 8 against Cincinnati, when he was hit by Joey Votto's line drive, fracturing his lower right leg.

With the Rockies leading 3-1 in the sixth, Cook had two outs with runners on first and third when manager Jim Tracy came out for a mound visit. Tracy left Cook in, but a wild pitch during Jorge Cantu's at-bat allowed Chase Headley to score. Cantu was intentionally walked to chase Cook and Alberto Gonzalez greeted reliever Matt Belisle with an RBI single to tie it.

Helton singled in the first, homered in the third and doubled in the fifth and seventh. Helton tied the game at 1 with his eighth homer, which sailed over the porch in the right-field corner.

Tulowitzki singled following Helton's two-out homer, advanced on Seth Smith's single, which hit second-base umpire Tim Tschida and scored on Ty Wigginton's single.

The Rockies made it 3-1 in the fifth when Helton doubled to the gap in left-center and scored on Tulowitzki's single to right.

The Padres loaded the bases on three singles in the second before Alberto Gonzalez brought in a run with a grounder for the second out. Moseley struck out to end the threat.
