Massey finished 2-for-4 with two home runs in the Royals' loss to the Yankees on Friday.
Massey entered the day in a bad offensive rut, but he parked a three-run shot to right field off Clarke Schmidt in the top of the fourth inning and added a solo drive off Tommy Kahnle in the top of the eighth. It was the first career multi-homer game for the 25-year-old second baseman, who now has six home runs in 243 plate appearances this year.
