Over his last two outings, Gio Gonzalez of the Washington Nationals has seen his ERA rise from 2.91 to 4.62. On Saturday, he lasted just three innings, allowing five runs on seven hits to the New York Mets, and the team is concerned that there might be something physically wrong with their pitcher.
