Mickelson started the final round three shots behind playing partner and 54-hole leader Paul Casey, but Mickelson made back-to-back birdies on 9 and 10 and again on 13 and 14 to surge ahead. Play was eventually suspended due to darkness, although Mickelson, who wanted to continue, wasn’t pleased. Mickelson was six under on the day when play was suspended, and Casey was even par.
Play resumes at 8 a.m. local (11 a.m. ET) on Monday with Mickelson leading at 18 under through 16 holes. Casey is at 15 under and has to clean up a 3-foot par putt on the 16th. The 17th is a par-3 and the 18th is a par-5.
Scott Stallings has the clubhouse lead at 15 under.
If Mickelson wins, it will be his 44th career PGA Tour victory and fifth career win at Pebble Beach, tying him for the tournament record. His last victory came at the World Golf Championships-Mexico Championship last year.

11:36 a.m.: That’s it for this event, folks. Check back on our social channels and homepage today as we’ll have lots of other goodies coming in.
11:34 a.m.: “It’s nothing like the course we will see [for the U.S. Open in June],” Mickelson tells Peter Kostis.
11:34 a.m.: Mickelson at 48 is the event’s oldest winner in tournament history. He’s now won this tournament FIVE times in his career.
11:33 a.m.: And Mickelson finishes it off in style, making his birdie putt from about eight feet to jump to 19 under and win by three. That’s a final-round seven-under 65 for Lefty.
11:30 a.m.: Casey still out, and he rolls in his birdie putt to get to 16 under and take solo second away from Scott Stallings, who was in the clubhouse at 15 under.
11:29 a.m.: Casey actually ended up in a tricky spot and had to putt, but he ran it about eight feet by.
11:27 a.m.: Phil will win in the U.S. for the first time in six years. Last two victories were the 2018 WGC-Mexico and the 2013 British at Muirfield. 2013 Waste Management Phoenix Open was his last U.S. victory.
11:23 a.m.: Mickelson with 140 left to the green. He’s hitting a nine-iron and sticks it pin high and to about 12 feet. There is your 2019 AT&T Pebble Beach Pro-Am champion, everyone.
11:22 a.m.: Casey with an iron… and he comes up short and left of the green. Should be a pretty easy up and down for birdie, but birdie isn’t gonna win this thing….
11:20 a.m.: Casey has 245 yards to a back pin here. Will need to fade it in.
11:18 a.m.: Mickelson lays up and it’s safe. Casey up next.
11:15 a.m.: Casey needs to play this hole much differently than Mickelson. He needs to get home in two and make eagle. He blasts it out there and looks good. Might have trickled into the rough. Big shot for Casey coming up.
11:14 a.m.: We’ll finish this off with the 531-yard par-5 18th. Mickelson leads by three, and no surprise here (OK, some surprise, since it is Phil) that he hits iron off the tee. Finds the fairway.
11:12 a.m.: Mickelson from about the same distance for his birdie…. misses on the short side. He taps in for par and we’ll head to 18 with Mickelson leading Casey by three.
11:11 a.m.: Casey from 7 feet, 5 inches… pushes it out left and it never moves. Misread the whole way.
11:09 a.m.: Phil and Casey just getting to the green on 17 now. Two outstanding shots there. Birdie putts coming.
11:07 a.m.: Nice little crowd out on the course today. Tickets were free. Cold morning but hey Phil is closing in on PGA Tour victory No. 44 here!
11:06 a.m.: Casey with a 7-iron on 17. He drops it close too, inside Mickelson’s ball. He needs to pick up a stroke on Phil here though. Birdie putts coming.
11:04 a.m.: Par-3 17th up next. Playing 181 yards and Mickelson, with his first shot of the day, drops it pin high and about 12 feet left of the pin. That might have sealed this thing.
11:03 a.m.: I’m glad Casey made that putt cause man that would have been a rough start to the day. Would have been over just like that!
11 a.m.: And good start for Casey, slides his par putt in on the right side and we’re off to 17. Phil leads by three.
