It's a First

Lots of first's tonight.

• First game for us at the new Nationals Park
• First grand slam in Nationals Park
• First time seeing a grand slam

The National's second baseman Felipe Lopez hit a grand slam, the fourth of his career and first grand slam in the new Nationals Park. The last member of the Nationals to hit a grand slam was outfielder Justin Maxwell on Sept. 11, 2007.

Lopez had a career-high six runs to help the Nationals beat the Mets, 10-5.
