B.J. Upton rounds the bases after leading off the fifth with a homer in the second game. His brother followed with another home run.


DENVER - In their first season with the Atlanta Braves, Justin and B.J. Upton have become the new bash brothers.

The power-hitting siblings cracked back-to-back homers for the first time, leading Atlanta past the Colorado Rockies 10-2 Tuesday night to complete a doubleheader sweep that began with the coldest game at Coors Field.

"It's always cool when you can see him have success before you and then you go up and do the same thing," said Justin Upton, acquired as part of a seven-player trade with Arizona in January. "It was definitely cool for us to tack on those runs when we needed them. That was nice."

It was the 27th time in major-league history that brothers homered in the same game, but only the second time they went deep in consecutive at-bats. Lloyd and Paul Waner of the Pittsburgh Pirates also accomplished the feat Sept. 15, 1938.

Atlanta manager Fredi Gonzalez said the Uptons were displaying the kind of 1-2 punch that the Braves were hoping for when they acquired them. B.J. Upton was signed as a free agent last winter.

"It makes your lineup a lot better when you've got B.J. going, and you've got Justin, too," Gonzalez said. "For me, Justin is your No. 3 hitter, and it doesn't matter who is on the mound that night."

Or what the weather is like, for that matter.

In the first game, Justin Upton, Dan Uggla and rookie Evan Gattis homered in support of a solid outing by Mike Minor as the Braves won 4-3 in a game that began with a temperature of 23 degrees.

The weather warmed up for the night game - but only a bit. It was 30 degrees at first pitch.

In the nightcap, B.J. Upton homered to left field off Jon Garland to start the fifth inning, his third of the season. Justin Upton drove Garland's next pitch to center for his major league-leading 11th home run.

"Mistakes," Garland said. "Maybe a wrong choice of pitches. When you miss with pitches, good hitters will get you."
