The San Francisco Giants have placed first baseman Michael Morse on the seven-day concussion list after his collision with starting pitcher Jeff Samardzija in the brawl against the Washington Nationals. Utility player Kelby Tomlinson has been called up to take Morse's spot on the roster. In the top of the eighth inning of Monday's game, Giants reliever Hunter Strickland threw at Nationals outfielder Bryce Harper and hit him in the hip.
