When the Braves went through the first two weeks of this season in near-perfect fashion, they were fueled by the consistent power provided by Justin Upton. Four months later, they are once again cruising with the benefit of Upton’s latest hot stretch. Upton hit a go-ahead eighth-inning home run that provided the Braves all they needed to notch their 11th consecutive victory with Monday night’s 3-2 win over the Nationals at Nationals Park.
