LOS ANGELES -- The Colorado Rockies are hoping to ride Troy Tulowitzki's phenomenal homer streak right into the postseason.

Tulowitzki hit two more home runs Saturday -- tying a modern major league record with 14 in a 15-game stretch -- and the Rockies kept up their pursuit of a playoff spot by routing the Los Angeles Dodgers 12-2 for their 20th victory in 26 games.

"I really don't have words to describe what we're seeing from Troy Tulowitzki," manager Jim Tracy said. "I mean, how do you describe 14 homers in 15 games? You know, it's one thing to be hot, and another to be in a zone like this guy is in. But he has that type of mentality. He loves this time of the year, and he's proven that going back to 2007."

The Rockies began the day 1 1/2 games behind San Francisco in the NL West, and chasing for the wild card.

Tulowitzki has four multihomer games this season -- all of them within his last 10 games -- and is hitting .394 with 35 RBIs in his last 16 contests. He joined Albert Belle (1995) and Barry Bonds (2001) as the only players since 1900 to homer 14 times in a span of 15 games.

"That's awesome. But I think the timing of it -- coming down the stretch here -- is what definitely makes me a lot happier with it because it's huge for our team," Tulowitzki said. "If you had to pick one time to do it, it would be now. So I'm definitely proud of that.

"I might not play any better than this in my entire career, so it's something that I'll always remember," he added. "But for right now, I'm not done with this."

The Rockies' shortstop hit a two-run homer in the first inning, doubled in the third and added another two-run shot in the fifth against rookie John Ely. Tulowitzki fouled out with the bases loaded in the eighth, but Melvin Mora hit a grand slam later in the inning. Mora also singled home a run. His five RBIs were one off his career best with Baltimore in 2008.
