British Open 2016 live stream: How to watch Sunday’s round online

Someone could yet make a Sunday charge, but with 18 holes left to play, the 145th Open looks an awful lot like a two-horse race between Phil Mickelson and Henrik Stenson, who seized control of the championship on Friday and moved further clear of the rest of the field on Saturday. Now they’ll duel for the Claret Jug.

Mickelson took a three-shot lead after Thursday’s first round, shooting a course-record 63 at Royal Troon. Stenson had the low round on Friday and cut Mickelson’s lead to one stroke, before Stenson’s 68 and Mickelson’s 70 on Saturday set the stage for Sunday’s drama, now with Stenson a stroke ahead. It’s almost certain that either Mickelson will win his sixth major or Stenson will win his first. Either would be a good story, but for different reasons.

At 46, Mickelson hasn’t won a major since he beat Stenson by three strokes at The Open in 2013, played at Muirfield. He’s fallen a bit from the top of the World Golf Rankings, to No. 19, and taken on at least some perception that he’ll never again win a major championship. A victory on Sunday would render such fears dead and buried.

Stenson has come close before, most notably at Muirfield in 2013. He’s also recorded top-four finishes at both the U.S. Open and PGA Championship, but he’s never won a major himself. Dustin Johnson’s June victory at Oakmont left Stenson as the highest-ranked golfer in the world (currently No. 6) without a major win on his account. Stenson still hasn’t made a cut on U.S. soil since April’s Masters, but he won the European Tour’s BMW International in Germany in June. It’d be nice to see Stenson land a big fish at some point, and there aren’t many better chances than this one. It’s his first solo 54-hole lead at a major championship, ever ... which is surprising given his talent and veteran status.

Trailing Mickelson and Stenson are Bill Haas (6-under), Beef Johnston (5-under) and J.B. Holmes (4-under). It’s not inconceivable that one of them could catch Stenson or Mickelson, but it won’t be easy. They’ll tee off just before the final group, which decreases the chance they’ll play in drastically different weather conditions. It’ll take a remarkable round and, probably, a lot of luck to reach the leaders.
