B.J. Upton and his brother Justin hit back-to-back homers for the first time, leading the Atlanta Braves past the Colorado Rockies 10-2 on Tuesday night to complete a doubleheader sweep that began with the coldest game at Coors Field. 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 on Sept. 15, 1938. 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.
