Minnesota Twins center fielder Byron Buxton left Sunday's game against the Kansas City Royals in the sixth inning due to a left knee contusion.

Royals starter Michael Lorenzen hit Buxton with a pitch in the fifth. Buxton stayed in to play the bottom of the fifth in the field, but James Outman took over in center in the sixth.

It was an unhappy ending to a milestone day for the 31-year-old All-Star. Buxton led off the game with a 402-foot homer off Lorenzen, which marked his 30th blast of the season as he joined Hall of Famer Kirby Puckett as the only Twins to record 30 homers and 20 stolen bases in the same season.
