George Kottaras added a two-run double in the 10th for Kansas City.
Alcides Escobar in the 10th. Eric Hosmer followed with a single and Billy Butler was intentionally walked to load the bases. Ross struck out Mike Moustakas and Lorenzo Cain before Lough came up. Lough was hit on a 2-1 pitch to force in the go-ahead run.
That snapped Ross' scoring streak at 20 1-3 innings.
Aaron Crow (1-1) pitched 1 1-3 innings of scoreless relief and Greg Holland pitched a perfect 10th to pick up his ninth save in 11 chances.
