David Wright sustained a concussion after being hit squarely in the helmet by a 94 mph fastball from Giants starter Matt Cain on Saturday, and the Mets third baseman was expected to spend the night in the hospital, according to an Associated Press report. Wright was examined in the clubhouse before being taken by ambulance to the Hospital for Special Surgery. Mets spokesman Jay Horwitz said Wright had a CT scan, which was negative. The Giants beat the Mets 5-4 in 10 innings.
