The perennial runner-up. The Open Championship first-timer. The redemption story.

Sunday at The British Open will have no shortage of intriguing storylines for a challenging finale at Royal St. George's. Louis Oosthuizen (-12) will look to hold onto his one-shot lead; he holds a slim edge over Collin Morikawa, who is a +200 option to win on his first appearance at the event. And let's not forget Jordan Spieth, who sits three shots off the pace in the latest chapter to his incredible 2021 comeback. 

With the final round set to tee off at Royal St. George's, we give our Open Championship golf picks, predictions and best bets for Round 4.

British Open Round 4 picks and predictions

Louis Oosthuizen Outright (+162)

Wire-to-wire winners don't come along all that often – in fact, it hasn't happened at the Open Championship since Rory McIlroy achieved the feat in 2014. But Oosthuizen has been full value for his one-shot lead, dominating Royal St. George's through the opening 54 holes. He's in the same position he was 24 hours ago, with just two others within three shots of the lead. Just as we projected Saturday, we see Oosthuizen using his sublime iron play and red-hot putting to finish atop the heap.

Jon Rahm Outright (+1,800)

If any player can storm back from five shots down in the final round of this tournament, Rahm has to be at or near the top of that list. He struggled through his first 11 holes but launched himself back into the periphery of the title conversation with three birdies over his final seven holes. He boasts the 10th lowest final-round scoring average on the PGA Tour, and has shot 68 or better in the last round of three of the past five majors. He's an underdog play, for sure, but he has the goods to make it interesting.

British Open matchup predictions

Low American: Jordan Spieth (+225)

We should see a flood of money coming in on Morikawa, both outright and on the low American prop. While you can't quibble with how sensational he has looked, these are great odds for Spieth when you consider that he was the outright leader early in his back nine before stumbling to three bogeys over his final seven holes, including a frustratingly short missed par putt on 18. His game is suited to the conditions these players will face Sunday, so he's worth a look here despite a two-shot deficit.

Chez Reavie Over Bryson DeChambeau (+163)

We could see a 63 from Bryson on Sunday. We could also see an 83. We don't really know which version of the enigmatic golfer will show up for Sunday's round – but after hearing him say that Royal St. George's has him "scratching (his) head," we're not exactly rushing to lock in our DeChambeau bets. Reavie was done in by a triple-bogey on the par-3 3rd but was otherwise solid and is coming off an eye-opening 66 in Round 2. We're much more confident in him, especially at this price.
