After getting through the first three innings without allowing a hit, Nationals starter Stephen Strasburg allowed a single to Juan Pierre in the fourth inning. One batter later, Pence sent a Strasburg curveball into the red seats in deep left-center field.
The Nationals got one of the runs back in the bottom of the fourth, when Chad Tracy golfed a solo home run into the Nationals bullpen off of Kyle Kendrick. But Ruiz answered in the top of the fifth by planting a Strasburg fastball beyond the center-field wall.
Pence's home run was the first Strasburg had given up since August 15, 2010.
