LAWRENCEVILLE — Atlanta Braves right-hander Tommy Hanson, pitching on a rehab assignment, threw five scoreless innings to lead the Gwinnett Braves to a 5-2 victory over the Louisville Bats on Sunday at Coolray Field. Ernesto Mejia, Rusty Ryal and Brian Friday all homered off Bats’ starter and former G-Brave Todd Redmond in a five-run fourth inning. Hanson (W, 1-0) allowed just three hits and two walks while striking out five in his first start for Gwinnett since May 31, 2009.
