ATLANTA — Rookie Andrelton Simmons made amends for his first career error by hitting a two-run, go-ahead homer in the sixth inning and the Atlanta Braves beat Baltimore 4-2 on Friday night to end the Orioles' five-game winning streak. Brian McCann's first-inning homer off Brian Matusz (5-7) gave Atlanta a 1-0 lead. The Orioles scored two runs off Tommy Hanson in the fourth with help from a throwing error by Simmons at shortstop and a fielding error by Michael Bourn in center field.
