DENVER -- In the offseason, the Atlanta Braves signed B.J. Upton as a free agent and traded for Justin Upton. The two brothers are playing side-by-side in the outfield, hitting back-to-back in the lineup and on consecutive pitches Tuesday night, they slugged their way into history.
The Upton brothers completed a very rare feat, something that had been accomplished just once before in major league history, some 75 years ago.
They hit back-to-back homers as the Braves beat the Colorado Rockies 10-2 to sweep a day-night doubleheader and continue their lopsided dominance of the Rockies. The only other set of brothers in major league history to hit back-to-back homers were Big Poison and Little Poison as Hall of Famers Paul and Lloyd Waner were known. The Waners hit back-to-back homers for the Pittsburgh Pirates on Sept. 15, 1938.
History was made in a blink-of-an-eye, two-pitch sequence against Jon Garland in the fifth. The Upton homers came after Juan Francisco hit a two-run homer off Garland in the fourth. Garland had allowed just one homer in 19 innings in his first three starts, but the Braves can strike often and strike quick.
Their three homers in two innings in the nightcap exceeded their rapid-fire slugging in the opener of the twinbill when they hit three homers in a four-inning span while winning 4-3.
The six homers the Braves hit in the doubleheader are equal to the Miami Marlins' total in 21 games this season. The Braves lead the majors with 35 homers in 20 games.
The beneficiary of the second-game barrage was Julio Teheran, who took the mound with a 7.31 ERA in three starts. Facing the Rockies for the first time, Teheran gave up one run and eight hits -- all singles -- in seven innings with no walks and three strikeouts. Teheran was extremely efficient, throwing 70 of his 90 pitches for strikes.
Garland pitched at least six innings for the fourth straight start, but after giving up 16 hits in his first three outings, the Braves banged out 10 hits. Garland also issued four walks, one more than in his previous three starts combined.
The doubleheader sweep improved the Braves' record to a major-league best 15-5 and came after they lost their final three games at Pittsburgh. They are 15-3 against the Rockies since the beginning of 2011, and they have hit 28 homers in those games to 10 for the Rockies. The Braves lead the all-time series with the Rockies 106-60.
The Braves blew the second game open with a four-run eighth that included run-scoring doubles from Justin Upton and Francisco off Josh Outman and a two-run single by Gerald Laird off Wilton Lopez.
NOTES: Braves right fielder Jason Heyward underwent an emergency appendectomy on Monday evening and was placed on the 15-day disabled list. Braves manager Fredi Gonzalez said he visited Heyward in Rose Medical Center in Denver before coming to the ballpark and Heyward was fine but "just drained" after surgery. Infielder Tyler Pastornicky was recalled from triple-A Gwinnett and was with the Braves for the first game. In Heyward's absence, Gonzalez said Johnson and Jordan Schafer would play right field. Upton played right field with Arizona before joining the Braves this year, but Gonzalez said he would leave Upton in left field, where he has played well and adapted to the position rather than move him to right field in Heyward's absence. ... Rockies pitcher Jhoulys Chacin, who is on the 15-day disabled list retroactive to Saturday, underwent an MRI on Monday that showed a mild back strain but no damage to his left oblique. "Everything was fine," Chacin said. "It's a strain in my back and a little bit in my lat, but it wasn't bad." Chacin, who is eligible to be activated May 5, will travel with the Rockies to Phoenix after Thursday's game. After the Rockies' weekend series there, he will report to their complex in Scottsdale, Ariz., where if all goes well -- and the Rockies don't have to adjust their rotation due to a postponement -- he will throw bullpen sessions in preparation for one rehab start April 30 before facing the Rays on May 5 at Coors Field. ... The previous low temperature for the start of a Rockies home game was 28 degrees on April 12, 1997, against Montreal and last Thursday against the New York Mets. Both of those were also day games.
