BOSTON— Jair Jurrjens showed the skill that made him an All-Star last season — before knee problems and two months in the minors sidetracked his outstanding career. In his first start since being called up, Atlanta's winningest pitcher in 2011 allowed one run on three hits and shut down the hot-hitting Boston Red Sox, leading the Braves to a 4-1 win on Friday night. "Awesome," Jurrjens said.
