The Open Championship wrapped up Sunday at Royal St. George's, and 2021 British Open odds now give way to the 2022 tourmanent, to be played at St. Andrews, the birthplace of golf.
Jon Rahm, fresh off his first major title at the U.S. Open, began the 2021 tournament as the favorite in odds to win the British Open, then yielded to Jordan Spieth after the first round. Then Louis Oosthuizen was favored before the third and fourth rounds, but it was Collin Morikawa who made his way to victory.
Below are the final in-progress golf odds to win The Open Championship at Royal St. George's Golf Course, from July 15-18, 2021.

Latest British Open betting action: Morikawa fends off Spieth
UPDATE 3 P.M. ET SUNDAY: On Saturday night, Neil Fitzroy said The SuperBook at Westgate had modest decisions to the top three players on the British Open odds board. Jordan Spieth, sitting third on the leaderboard, was actually a break-even proposition; leader Louis Oosthuizen was a small loser; and second-place Collin Morikawa was a small winner for the book.
At that point, Fitzroy said: "We do well to Morikawa in props. A lot of money came in against him in the top-five and top-10 markets. We also need him to beat Oosthuzien in a four-way group matchup. So we’ll be pulling for Morikawa in all the markets we offered."
With that in mind, Sunday couldn't have gone much better for Fitzroy and The SuperBook risk room. Morikawa shot 4-under 66 for a 15-under 265 total and a two-shot victory over Spieth, giving the 24-year-old his second major championship.
"He was a small winner for us in futures. He was great for us in the props," Fitzroy told Covers shortly after Morikawa hoisted the Claret Jug.
Further, The SuperBook avoided the prospect of back-to-back major titles from Jon Rahm, who matched Morikawa's Sunday 66 but finished four shots back in a tie for third with Oosthuizen. Rahm was The SuperBook's worst to-win outcome among those in contention in Round 4.
The story was a bit different at PointsBet USA, where bettors got a more positive outcome.
"Morikawa was our fourth-biggest liability, behind [Brooks] Koepka, Oosthuizen and Spieth, and he was first in handle by a wide margin," PointsBet's Wyatt Yearout said.
Previous British Open action
UPDATE 5:30 P.M. ET SATURDAY: Louis Oosthuizen shot 1-under 69 after rounds of 64-65 Thursday and Friday, and he remains the leader with a 12-under 198 total. As such, The SuperBook has Oosthuizen a +140 favorite to hoist the Claret Jug come Sunday evening at Royal St. George's. But right behind him is Collin Morikawa, who shot 68 for a 199 total and is the +190 second choice on the British Open odds board. Jordan Spieth would be right there, as well, if not for bogeys on Nos. 17 and 18 Saturday, but he's not far back as the +500 third choice with a third-place total of 9-under 201. "Spieth is basically break-even for us. Oosthuizen is a small loser. Morikawa is a small winner," SuperBook risk manager/golf oddsmaker Neil Fitzroy told Covers. The SuperBook also has a couple of needs in the prop bet markets. The total winning score prop opened at 271.5 and closed 272.5 (Over -120). "We need the Under." Fitzroy also noted the book needs Morikawa beyond the to-win market, as bettors went against him in top-five and top-10 props, among other markets.
UPDATE 5:30 P.M. ET FRIDAY: Louis Oosthuizen followed his scorching Round 1 of 6-under 64 with a 5-under 65 Friday in Round 2 for an 11-under 129 total, two shots clear of the field. That prompted William Hill US director of trading Nick Bogdanovich to make Oosthuizen the +200 favorite to hoist the Claret Jug come Sunday evening at Royal St. George's. Collin Morikawa and Jordan Spieth are the +450 co-second choices, with Morikawa firing a Friday 64 for a 131 total and Spieth shooting 67 for a 132 total. So far, William Hill US customers have pegged this tournament just right. "I commend the bettors. Out of 156 players, the most tickets are on Oosthuizen and the second-most tickets are on Spieth. Very astute handicapping by the bettors," Bogdanovich told Covers, while noting WillHill is rooting against both those players. "We lose with Oosthuizen, we lose with Spieth. Those two are bad, the rest are doable."
UPDATE 7:45 P.M. ET THURSDAY: Round 1 is in the books, and Jon Rahm is no longer the favorite after a 1-over 71 that left him way back in a tie for 74th. In his place now stands Jordan Spieth, who fired a 5-under 65 to stand tied for second with long-shot Brian Harman, one stroke behind Louis Oosthuizen. BetMGM Nevada has Spieth and Oosthuizen as +450 co-favorites on the British Open odds board heading to Friday's Round 2. Spieth is the bigger concern, after opening +4,000 in January and getting as short as +1,600 pre-tournament. "Spieth is bad for us," BetMGM Nevada's Scott Shelton told Covers, noting that on Wednesday, a Vegas customer put $10,000 on Spieth +1,800, a potential $180,000 payout. Shelton said Oosthuizen is a modest loser for the book. After those two, the odds to win the British Open fall off noticeably to +1,600 third choice Collin Morikawa, tied for ninth after a 67. Several players near the top of the leaderboard are great outcomes behind the counter, including Harman, who's now +2,500. "He's a huge winner for us. There are only nine tickets on the guy, and the biggest is $100 at 125/1, to win $12,500," Shelton said.
UPDATE 10 P.M. ET WEDNESDAY: Just a few hours before the first ball sails off the tee at Royal St. Georges, Jon Rahm is the +1,000 favorite on William Hill US's British Open odds board, a slight adjustment from his +900 price earlier today. Rahm, who won the U.S. Open last month for his first major title, is tied for second in tickets and is No. 1 in money at WillHill US. Louis Oosthuizen (+2,000) leads the ticket count and is tied for third in money, while +1,400 co-second choice Brooks Koepka is tied for third in tickets and is second in money. There's a $1,000 play on Koepka at 14/1 and $1,000 bets on Rahm at +1,200 and +900. A much larger payout looms on Viktor Hovland, $5,000 at +3,000 for a potential $150,000 win, and Hovland is now the +2,200 eighth choice. Perhaps surprisingly, Dustin Johnson slipped from +1,200 to +2,500 and Bryson DeChambeau from +1,800 to +3,500. "I just keep pushing them up to see if anyone will take them at some price," WillHill director of trading Nick Bogdanovich said. "Those are the two that bettors have been ignoring." Bogdanovich also pointed out some long-shot wagers: $500 on Byeon Hun An +50,000 (500/1), to win $250,000; $750 on Brian Harman +25,000 (250/1), to win $187,500; and $1,350 on Francesco Molinari +7,500, to win $101,250.
UPDATE 9:30 A.M. ET WEDNESDAY: When The SuperBook first put up British Open odds in December, Nos. 1-3 on the board were Dustin Johnson, Rory McIlroy and Jon Rahm. Seven months later, Jon Rahm is the +900 favorite, followed by McIlroy, Brooks Koepka and Xander Schauffele, all at +1,600. Johnson slid all the way to +2,500, then rebounded slightly to +2,200. SuperBook risk manager/golf oddsmaker Neil Fitzroy said Koepka and Rahm are tied atop the ticket count, followed by Jordan Spieth (+1,800) and Louis Oosthuizen (3,000). Rahm leads the way in money, with Koepka second and McIlroy third. "Good outcomes near the top of the board include Bryson Dechambeau, DJ and Patrick Cantlay," Fitzroy said. "There's no interest at all in Bryson. He has a new caddy on the bag, and links golf doesn't seem like a great fit for his game." Among those near the top of the odds board, Fitzroy said Rahm, Koepka and Patrick Reed (+3,000) are the largest liabilities. "Some longer shots creating liability include defending champ Shane Lowry at 80/1, and he's currently 40/1; Lee Westwood at 60/1, where we currently are; Phil Mickelson at prices ranging from 100/1-150/1, and he's currently at 125/1; and Kevin Kisner at 200/1 and 150/1, and he's currently 125/1," Fitzroy said.
UPDATE 1 P.M. ET ET TUESDAY: Jon Rahm, who nabbed his first major title by winning the U.S. Open in June, is the betting favorite to make it two in a row. BetMGM Nevada opened Rahm the +1,100 second choice on Jan. 27, behind +1,000 Dustin Johnson, and the Spanish star initially dipped to +1,200, but he's now the +750 favorite on the British Open odds board. However, BetMGM Nevada's Scott Shelton said bettors are looking elsewhere this week. "Rahm is a great outcome for the book," Shelton said, while noting the ticket count and money leaders at BetMGM's Las Vegas sportsbooks. "Louis Oosthuizen, Rory McIlroy and Brooks Koepka are top three in tickets, in that order, and top three in money are Koepka, Oosthuizen and Rory, in that order." Koepka is +1,400, McIlroy +1,800 and Oosthuizen +2,800. Thirty-six hours before the first tee time, Koepka and Oosthuizen are Nos. 1 and 2 in liability for BetMGM Nevada. "No one is touching Koepka or Oostie, Koepka is the biggest liability of all the contenders," Shelton said, noting one customer put $5,000 on Koepka at 14/1 to win $70,000.
