Washington Nationals first baseman Ryan Zimmerman drove in all four of the team's runs Sunday, going 1-for-4 with a three-run homer against the Oakland Athletics. Zimmerman is playing against all lefties, and in true fashion his home run came off of left-handed starting pitcher John Means. It was his 11th of the year. Zimmerman has not been particularly good this season, producing just a .729 OPS in 174 at-bats, but he could be valuable to fantasy managers with daily lineup changes.
