KISSIMMEE, Fla. — Justin Upton was eager to get his first hit with the Atlanta Braves. Boy, it was a memorable one Monday, even if it was just spring training. Upton launched one of the longest home runs ever seen at the Disney World complex, a towering drive that cleared the grass berm beyond left field, as the Braves picked up their first win of the spring with a 7-6 victory over the Miami Marlins.
