Adam Dunn hits three home runs in the Nationals’ 7 – 6 win over San Diego, driving in 5 runs.

In the 9th, pinch hitter Matt Stairs of the Padres hits a solo homer off Matt Capps, the 20th of his career, tying the record held by Cliff Johnson. However, Capps holds on for his 23rd save. San Diego’s Adrian Gonzalez and Washington’s Ian Desmond also go deep on a night when the long ball is king.
