Nationals infielder Zach Walters hit his first major-league home run Tuesday against the Marlins, and he didn't wait long to hit his second. Walters put the Nationals up for good in a 6-3 win, with a pinch-hit home run to left off Mike Dunn to open the eighth inning.
Walters has appeared in three games as a sub since joining the team, and has two hits in four at-bats, both home runs.
