The Mariners looked well on their way to win 11 in a row, until the Royals scored four runs in the eighth inning to pull off the rally. Salvador Perez started off the game with a bang, hitting a three-run homer in the first inning. Eugenio Suarez got the M’s back in the game with a two-run homer in the second inning. Seattle would gain the 4-3 lead in the eighth on a solo shot. But it was Adam Frazier who got the last laugh, hitting a two-run homer in the eighth to get the go-ahead run. The Mariners scored one in the ninth, but it came on a double play which was not enough to pull off a rally themselves.
