Buehler was optioned to the minors Saturday, Bill Plunkett of The Orange County Register reports.
The move doesn't appear to be performance-related, as Buehler had a solid start Friday, giving up two runs in five innings against the Angels. The Dodgers can send him down for 10 days now, though, without having him miss a start, allowing them to have an extra arm (Zac Rosscup) in the bullpen. Expect Buehler to return soon after the break and return to the Dodgers' rotation.
