Golf: Dustin Johnson pipped after 'unbelievable' putt topped by Jon Rahm's monster

Dustin Johnson has made an "unbelievable" 45-foot (15m) putt to force a playoff at the PGA Tour's BMW Championship, but could only watch as Jon Rahm nailed an even bigger one on the first extra hole.

Rahm clinched the title with a putt from 66 feet on the same 18th hole to win.

"I was kind of laughing at my putt," Johnson says, after shooting a closing 67 to finish locked with Rahm. "Because it was one of those where you're not really thinking you're going to make it.

"I played an unbelievable putt, got in the playoff and then Jon made an even more ridiculous putt on top of me."

Johnson had the opportunity to force a second playoff hole, but missed his own long birdie putt, ensuring that Rahm would enter next week's Tour Championship in Atlanta second in the FedEx Cup points standings behind the American.

"I gave it a good effort," Johnson adds of his second long putt in a matter of minutes on the 18th hole. "I thought I made it when it was coming down the hill.

"It just kind of ran out of a little bit of speed and missed just low."

Johnson says he feels in good shape heading into East Lake next week.

"I thought I played really solid all day long, I like my position," he adds.

"I'm really, really pleased with all aspects of the game."
