Team trainer Steve Sayles said that the team will follow a wait-and-see process to determine what Barton is capable of doing with the break, before making a decision on his availability.
Barton injured his finger in the seventh inning of Sunday's game, while sliding into the visitor's dugout after making a catch in foul territory. Barton was replaced in the A's lineup by Rajai Davis in the bottom of the seventh, and Adam Rosales took over at first base beginning in the eighth. Barton quickly made his way out of the clubhouse following the game.
It marked a bittersweet day for Barton, who exited with three hits. He's no stranger to bumps and bruises, though. Barton has had his fair share of mild injuries this year yet is still one of just two A's players to start all 19 games.
Barton will receive an extra day of rest because the team has a scheduled off day Monday and will use that time to travel to Tampa Bay, where it begins a two-city, six-game road trip.
