Michael Harris hit a grand slam in his first at-bat after missing nearly two months because of a hamstring injury, helping the Atlanta Braves rout the San Francisco Giants 13-2 on Wednesday night. Activated from the injured list before the game, Harris crushed an 0-1 curveball from Robbie Ray (2-2) into McCovey Cove for his first career grand slam and Atlanta's fourth of the season. Grant Holmes (1-0) had six strikeouts in seven innings in his first career victory.
