ATLANTA — Andrelton Simmons hit a two-run double in the eighth inning and the Atlanta Braves, boosted by Julio Teheran's sharp outing, beat the St. Louis Cardinals 2-0 Saturday in a matchup of NL division leaders. Teheran allowed two hits in seven innings, striking out six and walking one. Simmons' bases-loaded, two-out double came on a 99 mph fastball from Trevor Rosenthal.
