SAN DIEGO -- Rockies outfielder Cory Sullivan didn't have time to stop and think about history.
Sullivan tripled twice in the fifth inning of Sunday afternoon's 10-4 victory over the Padres, tying a Major League record for three-baggers in an inning, last accomplished by Gil Coan of the Washington Senators on Aug. 21, 1951.
Sullivan lashed a leadoff triple to right field off San Diego starting pitcher Jake Peavy, then achieved another three bases against Chan Ho Park with two outs in Colorado's seven-run inning. But the seven-run frame was so long and so fruitful, Sullivan didn't realize he was entering the record books.
"I didn't even realize I'd hit two triples in one inning until somebody said it to me after the game," Sullivan said. "I had no idea. I thought it was in a different inning. It just didn't occur to me.
"It's always good to have things happen that don't happen every 55 years."
It was the 11th time a player has achieved the feat. Sullivan also is the first National Leaguer with two triples in an inning since Curt Walker did it for Cincinnati on July 22, 1926.
The Rockies had another triple in the inning, as Brad Hawpe drove in two runs and chased Peavy from the game. The three triples tied a team record for triples in a game.
Jason Smith followed Hawpe's triple with his second homer of the game, and the Rockies turned a 3-2 deficit into a 9-3 advantage.
Sullivan also doubled in the third inning. Since starting the season 1-for-10 in three games at Coors Field, he is 9-for-15, with three doubles and three triples.
"It's just getting into the ebb and flow of the season," Sullivan said. "I struggled a little bit at the beginning, but once you find you groove, you try to stay in it."
Rockies manager Clint Hurdle said: "Offensively, he's been able to pick it up a notch since we left town. He's seeing the ball better. He's actually hit some offspeed pitches, which he can do, [but] when he gets in a hurry, he doesn't do. He's settled in up there, got his jitters out the way and now he's just playing ball."
