Jacob Wilson

Jacob Wilson is day-to-day with left hamstring tightness.

Athletics manager Mark Kotsay expressed optimism that Wilson will be ready for Friday’s series opener against the Royals. The 23-year-old rookie sensation is on the bench for the second consecutive contest on Wednesday afternoon for precautionary reasons. He’ll benefit from an extra day of rest on Thursday before the A’s kick off a three-game series in Kansas City.
