Warming up in the bullpen before his first start of the season, Washington Nationals lefty Gio Gonzalez got hit by a severe headache. Maybe it was because the Florida native was bothered by the temperature in the 40s. Wasn't really sure. He took a couple of pills. He got his right temple massaged by a trainer. Still, he couldn't shake the pain, inning after inning -- and it did not affect him one bit. Gonzalez hit his second career homer -- grinning his way around the bases -- and pitched six scoreless innings, helping reigning NL East champion Washington beat the Miami Marlins 3-0.
