DENVER (AP) -Troy Tulowitzki is on such a September surge, he'll surely hate to see the calendar flip - unless the Colorado Rockies are still playing deep into October.

And if he stays this hot, they just might.

Tulowitzki had his third multihomer game in a little more than a week and tied a career high with seven RBIs to help the Rockies beat the NL West-leading Padres 9-6 Wednesday and avoid a series sweep.

The smooth-fielding shortstop's 11 homers in September are just one shy of tying the franchise mark for any month - and he still has half a month left to go.

``The game's not that easy. I'm just hot right now,' Tulowitzki said. ``I'm continually trying to remind myself to enjoy this while it last. It's not going to last forever.'

The Padres saw their division lead shrink to a half-game over second-place San Francisco Giants, who beat the Dodgers 2-1.

Powered by Tulowitzki and Jorge De La Rosa, who gave Colorado's beleaguered bullpen a break by pitching into the eighth, the Rockies climbed within 2 1/2 games of San Diego. They also closed within 2 1/2 games of Atlanta in the wild-card race.

As locked in as Tulowitzki has been lately, Rockies manager Jim Tracy figured he would lead the team out of its two-game mini-funk.

``This is as competitive of player as I've ever seen,' Tracy said. ``You could tell from that first at-bat that he wasn't going to let us lose.'

Adrian Gonzalez nearly matched Tulowitzki's offensive production. The first baseman hit two homers to run his season total to 29, including a three-run shot in the eighth that wiped out half of a 9-3 deficit. He finished with five RBIs.

De La Rosa (8-4) yielded five runs and six hits in 7 1-3 innings.

Colorado starters have been awful of late, overtaxing the bullpen. That cost them dearly Tuesday night when Edgmer Escalona's failure to cover first base on a grounder to Todd Helton in the ninth inning led to the decisive run in a 7-6 loss.

``He stepped up and gave us exactly what we needed,' Tracy said of De La Rosa.

Colorado won the final game of a three-game series - not exactly what the team had in mind when the slumping Padres arrived at Coors Field on Monday. The Rockies were riding a 10-game winning streak and had designs on overtaking the Padres.

``It goes without saying - we needed that game. We simply need that game,' Tracy said.

NL MVP candidate Carlos Gonzalez finished 2 for 4 with two RBIs, increasing his NL leads in batting average (.341) and RBIs (106).

Tulowitzki is making a late MVP push, as well, despite missing 33 games with a broken wrist. He went 3 for 5 to raise his average to .325, second to Carlos Gonzalez.

``Between him and Carlos Gonzalez it's hard to find a couple of guys that are hitting the ball as well as they are,' said Padres pitcher Clayton Richard (12-8), who allowed a season-high eight runs and 11 hits in three innings.

In the eighth inning, the Padres had to pick their poison and elected to walk Carlos Gonzalez with a runner on second and face Tulowitzki. The strategy worked when Ernesto Frieri retired Tulowitzki on a hard lineout to left.

Pitch to a player with seven RBIs, though?

``Pretty crazy,' Carlos Gonzalez said, grinning. ``I'm not sure about that one.'

Tulowitzki understood the rationale - a right-hander coming in to face a righty. It wasn't an insult.

``They're playing the odds,' Tulowitzki said. ``At the same time, I put a good swing on that. That will stay in their minds.'

Richard gave up a three-run homer to Tulowitzki in the third. An inning later, Richard was pulled with the slugger stepping into the batter's box, and Edward Mujica gave up Tulowitzki's second three-run drive.

``He was on everything. He's been swinging the bat great for them, and today, boy was he locked in,' Padres manager Bud Black said. ``He was on fastballs, curveballs, sliders, changeups. He had some terrific swings.'
