Massey went 3-for-5 with two RBI in Tuesday's 10-8 extra-inning loss to the Mariners.
Massey played a key role in the Royals' ninth-inning comeback with a two-run single. The second baseman has put together a solid August, batting .294 with two home runs, three doubles and nine RBI over 14 contests this month. He's up to a .230/.282/.373 slash line with 10 homers, five stolen bases, 39 RBI and 26 runs scored through 93 contests.
