Byron Buxton left Wednesday's matinee game against the White Sox in the second inning when he appeared physically uncomfortable after sliding into second base on a stolen-base attempt.

Buxton was thrown out on the play – he didn't even attempt a slide – and was walked to the dugout with the aid of a trainer. He did not return to center field in the bottom of the second, instead being replaced by Willi Castro.

Buxton had started just four of the previous nine games, telling media earlier this week that he was dealing with soreness.

This is a developing story.
