KANSAS CITY -- Royals outfielder David Lough sustained a mild right hamstring strain while running to first base in the ninth inning of Wednesday night's 7-6 loss to the Rangers.
With a runner at first and one out, Lough hit a ground ball to Rangers first baseman Mitch Moreland, who threw to shortstop Elvis Andrus to get an out at second. But Lough was able to beat the throw to first, preventing a double play.
After five pitches to Alcides Escobar, Lough was removed from the game and replaced with pinch-runner Jarrod Dyson, who scored from first on Escobar's single to center.
Royals manager Ned Yost said Lough would miss at least Thursday's series finale, getting a day off to recover.
