PHOENIX — Justin Upton snapped a 14-game homerless drought and had four hits to help the Atlanta Braves rout the Diamondbacks 10-1 on Monday night in his return to Arizona. Upton, the first overall pick by Arizona in the 2005 amateur draft, was playing his first game at Chase Field since the offseason trade that sent him and third baseman Chris Johnson to Atlanta in a seven-player deal. Upton followed his brother B.J., who was hit on the left shoulder by Wade Miley (3-2) to lead off the sixth, and powered a fastball onto the porch above the center field fence for his 13th home run and first since April 27 at Detroit.
