Rahm comes up clutch in playoff vs. Johnson to win BMW Championship

What. A. Finish.

The grueling week at Olympia Fields - one that felt more like a U.S. Open than the BMW Championship - ended in a dramatic playoff between two of golf's biggest heavyweights, world No. 1 Dustin Johnson and No. 2 Jon Rahm.

Johnson entered Sunday's round sharing a two-shot lead with Hideki Matsuyama, but found himself trailing with one hole remaining after Rahm erased his three-stroke deficit with a bogey-free 64 to take the clubhouse lead at 4-under.

Needing a birdie on 18 to force a playoff, Johnson came up clutch by draining a double-breaking 43-footer. The few gathering around the final green erupted with cheers, stopping Rahm in his tracks while he was staying loose on the range.

But in the playoff, it was Rahm who delivered the knock-out blow.

After both players safely found the green in regulation, but neither closer than 30 feet for birdie, Rahm lined up his lengthy putt that seemed nearly impossible to make. From 66 feet with multiple twists and turns, Rahm made his stroke, and the ball tracked perfectly to the center of the cup.

Johnson failed to come up with an answer to Rahm, which sealed the 25-year-old Spaniard's second victory since the restart in June, fifth career win on the PGA Tour, and 11th worldwide.

"I still can't believe what just happened, what happened the last hour of play," Rahm said following his win.

"That stretch of waiting for DJ, him making the putt, going in the playoff, me making the putt, then trying to stay mentally in it just in case he made the last putt, it's been a roller coaster but so much fun," he added.

Rahm went 66-64 on the weekend at Olympia Fields and made one bogey over his final 36 holes. His only blemish was a penalization for mistakenly picking up his ball without marking it during Round 3, which afterward he said, "I just hope I don't lose by one."

The BMW Championship winner moved from No. 9 on the FedEx Cup points list to No. 2 with $15 million up for grabs next week.

For Johnson, it's his second runner-up result in his last three starts. He came second at the PGA Championship before winning The Northern Trust last week by 11 strokes. He remains No. 1 in the world and first on the FedEx Cup points list going into the Tour Championship.
