Mead went 2-for-5 with a solo home run and a second run scored in Wednesday's loss to the Giants.
The 25-year-old has emerged as a key part of the Nationals' surprisingly potent offense while becoming the team's primary option at third base. Over the last 15 games, Mead is slashing .259/.344/.574 with five of his 10 homers on the season, and 12 of his 29 RBI.
