Collin Morikawa joins list of largest blown 54-hole leads in PGA Tour history

He breezed through 54 holes at the 2023 Sentry Tournament of Champions without a bogey. He went to sleep on a six-shot lead after shooting 64-66-65 over the first three days.

His lead grew to seven during the final round but when Collin Morikawa bogeyed the 14th hole, things seemingly started slipping away and fast. He then bogeyed the 15th and then the 16th. To recap: Morikawa had 67 straight holes without a bogey and then three bogeys in a row.

Meanwhile, Jon Rahm started heating up. A first-hole bogey actually dropped him nine shots back of Morikawa but he then birdied five of his next eight holes to make the turn in 32. Three more birdies on Nos. 12, 13 and 14 and an eagle on the 15th hole rocketed Rahm into the outright lead.

Rahm then birdied the 18th hole for a 63 to get to 27 under and claim a two-shot win over Morikawa.

It was an amazing turn of events at the first tournament of 2023, as Morikawa joins a short list of nine golfers who also blew a six-shot, 54-hole leads on the PGA Tour.
