Briefly: Justin Thomas shoots 61, breaks Medinah's record

Justin Thomas opened with five straight birdies, added a pair of eagles and shot an 11-under-par 61 Saturday. And he did all that where? Medinah Country Club of Illinois, where three U.S. Opens, two PGA Championships and a Ryder Cup have been played.

Thomas broke the course record by four strokes and leads the PGA Tour's BMW Championship by six strokes.

Thomas hit a 5-wood to 2 feet for an eagle on No. 10, holed out from 180 yards with an 8-iron on No. 16 and made eight birdies.

He was at 21-under 195, six shots clear of Tony Finau and Patrick Cantlay.

Rain overnight had left Medinah as vulnerable as 7,500-yard courses get.

"It doesn't matter what golf course it is," Thomas said. "You give us soft, good greens and soft fairways, we're going to tear it apart. It's just how it is."

Josh McCown's retirement lasted two months, just long enough for the Philadelphia Eagles to realize they need him.

The Eagles signed the 40-year-old quarterback to a one-year deal, and he is coming out of retirement to join his 11th team and play his 17th season.

McCown provides insurance behind Carson Wentz, who was injured the past two seasons.
