Davis Riley makes Byron Nelson cut thanks to last-hole eagle - ESPN

PGA Tour golfer Davis Riley made an eagle on his last hole of the second round in the CJ Cup Byron Nelson on Saturday, which he desperately needed to get inside the cut line after being assessed a two-stroke penalty for accidentally using the slope feature on his distance device on an earlier hole.

Riley was 5 under after 36 holes, which was the projected cut line with a handful of golfers still playing at TPC Craig Ranch in McKinney, Texas. The second round wasn't completed on Friday because of inclement weather.

Riley, the 98th-ranked player in the world, informed a PGA Tour rules official that he had seen the adjusted distance for slope when measuring his tee shot on the par-3 17th hole, his eighth hole of the round.

The PGA Tour is experimenting with allowing golfers to use range finders in an attempt to speed up play, but they're not allowed to use the slope features. It's the third event in which the devices are being used.

«Unfortunately, it was just kind of one of those moments where your heart sinks a little bit, like you're just throwing away two shots,» Riley said. «It is what it is. That's the rules of golf. And we certainly have a trial period here with this, and I know the [United States Golf Association] is trying to do something about the range finder and the pace of play.»

Riley hit his tee shot on No. 17 to 12 feet and made par. After finishing the hole, he informed PGA Tour rules official Ken Tackett about the incident. Tackett told him there would be a two-stroke penalty because he had breached rule 4.3, and Riley would be disqualified from the tournament if it happened again.

The double-bogey 5 dropped him to 3 under. He carded birdies on Nos. 18 and 4, and bogeys on 3 and 6, which left him needing
