Highlights | Round 4 | AT&T Pebble Beach 2019

Mickelson had to come back Monday morning to finish off his three-shot victory over Paul Casey, which marked his record-tying fifth tournament title and win No. 44 of his illustrious career.

CBS will provide live coverage of the event via its website, with coverage starting at 11 a.m. ET and continuing until play is finished.

Third-round leader Paul Casey, who mixed two bogeys with two birdies, was at 15 under with three holes remaining, tied with Scott Stallings who finished with a 66.

He will return to Pebble Beach in June for the U.S. Open, where he made his pro debut in 1992.

The popular lefthander has been a US Open regular since Irwin's victory nearly 29 years ago and he's finished second an incredible six times in the event. Casey and FedEx executive Don Colleran had a one-shot lead in the pro-am. "I'll deal with that in six months".

As for that "longest event in PGA Tour history", it's a mark that seems destined to stand. Mickelson won at the course for the first time in 1998 and the tournament was suspended for six months because of a several days of poor weather on the Monterey Peninsula.

It was a decision Mickelson clearly disagreed with, visibly shaking his head when the horn blew to officially halt play.

It also would be his first victory on American soil since the Phoenix Open six years ago.

That also led him to enter this week's Genesis Open, which he had not planned to play, prior to defending a title at the WGC-Mexico Championship next week.

He believes power and the short game are the keys at the Masters and Pebble Beach confirmed not just that he's on track to contend at Augusta, but that there's hope for golf's 40-somethings, including Tiger Woods.

After playing the 17th and 18th on Monday, Mickelson admitted Casey was right.

Even so, it was the fourth time Casey took a 54-hole lead of at least two shots into the final round on the PGA Tour and failed to win.

"A phenomenal round of golf, " Casey said.

@PhilMickelson is a 44-time victor on the PGA TOUR. Mickelson marked his ball all week with a silver coin given to him by his grandfather, Al Santos, one of the original caddies at Pebble Beach in 1919.

"I can see fine", Mickelson told a rules official on the 16th green.

There was never a reasonable chance to finish in his pro-am format, with mostly foursomes across the golf course. "Sometimes I get in my little bubble and don't see the bigger picture". Mickelson poured it on, showing his skills have not deteriorated a bit at age 48, controlling spin beautifully to back pin positions. He closed with a 65 for a 10-under-par 278 total.
