Mead went 1-for-3 with a walk and a three-run home run in Tuesday's win over the Royals.
The 25-year-old infielder produced the game's deciding runs when he took Daniel Lynch deep in the seventh inning to break a 3-3 tie. Mead still isn't stringing together hits consistently, but over his last 20 games he's slashing .239/.325/.521 with six of his 11 long balls on the season, along with 12 runs and 17 RBI while emerging as the Nationals' starting third baseman.
