MLB: Back to back home runs for Upton brothers as Atlanta brave temperatures to beat Colorado
Brothers BJ and Justin Upton hit back-to-back homers as the Atlanta Braves beat the Colorado Rockies 10-2 to complete a sweep of their double-header on a cold day in Denver.
The siblings become only the second in major league history to score back-to-back home runs as they braved -5C temperatures to guide the Braves to victory.
"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."
Justin had homered in game one to help the Braves to a 4-3 win, then repeated the feat in game two, immediately after his brother had also gone yard off Jon Garland, for his MLB-leading 11th homer.
It was the third time this season the pair have both homered, but the first time they have done it back to back.
Fredi Gonzalez, the Atlanta manager, said the Uptons were displaying the kind of 1-2 punch that the Braves were hoping for when they acquired them.
"It makes your line-up 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."
