Blue Jays pitcher J.A. Happ has been hit in the head by a line drive and taken off the field on a stretcher during Toronto's game against Tampa Bay. Desmond Jennings' second-inning liner caromed off the left side of Happ's head, and the ball went all the way into the right-field bullpen. Happ fell down at the front of the mound, holding his head with his glove and bare hand. Jennings ended up on third base with a two-run triple. Team trainers, paramedics and medical officials rushed to Happ's aid as Tropicana Field fell into an eerie hush.
