Hayes went 1-for-2 with a solo home run and a walk in Sunday's 5-3 extra-inning win over the Cardinals.
Hayes has gone 4-for-22 over 10 games since he returned from a bulging disc in his back. The third baseman has settled back into a part-time role, battling for playing time with Eugenio Suarez and Sal Stewart at the hot corner. Hayes is hitting a meager .148 with a .443 OPS, three home runs, six RBI, 13 runs scored and one stolen base over 152 plate appearances this season.
