Oddsmakers not giving Jordan Spieth much of a chance to complete career Grand Slam at 2026 PGA Championship

Spieth has reiterated his belief that he is close to rediscovering his best form and recently changed his driver, 3-wood and golf ball as part of a reset. His last Top 10 at a major was a T-4 at the 2023 Masters.

"If you look at the stats, yeah, it's a Whac-a-Mole situation because I have had weeks where I'm leading in putting, weeks where I'm leading in driving, weeks where I am leading in ball striking, and then I just haven't been able to kind of put them all together," he said Monday. "I went on a run of feeling like I was contending or having a good chance of contending at every major for a number of years, and then it was periodic, and I feel like I'm close to being able to go back to doing that again."

To finish as top American this week, Spieth is priced at +3000, with of course world No. 1 and defending champion Scottie Scheffler as the clear +220 favorite. This is only the second major championship that Aronimink, a par 70 at 7,400 yards, will host after the 1962 PGA Championship won by Player. The course has hosted a few regular Tour events since then, last the 2018 BMW Championship as part of the FedExCup playoffs won by Keegan Bradley. Spieth was T-55. All of the Top-5 finishers from that BMW are in this field.

One trend certainly working in Spieth favor is that an American has won the Wanamaker Trophy each of the past 10 years and one doing so Sunday is the -142 favorite. But eight of the past nine major champions overall were among the top-five betting favorites to win, and Spieth is nowhere near that. The lone major winners since 2024 with pre-event odds outside those favorites was JJ Spaun at the 2025 U.S. Open, when he was tied as the 38th favorite.

The past nine PGA Championship winners have been golfers who currently have multiple majors. Seven of those nine entered the tournament inside the world top 15. Spieth is 51st. At FanDuel, he is -225 to make the cut and +156 to miss. I could see a Top 20 finish at +280 but likely no better. Spieth is -120 in a head-to-head with Patrick Reed (-110) and tees off at 8:40 a.m. ET on Thursday in a star-studded trio with McIlroy and Jon Rahm.

Weather shouldn't be an issue this week. Only highs around 66 Thursday with 15% chance of rain, but the rest of the weekend looks warmer and dry. If there is a playoff, it will be three-hole aggregate and played on Nos. 10, 17 and 18. Then it's sudden death on 18. The last PGA Championship playoff was in 2022 when Justin Thomas beat Will Zalatoris in Tulsa.
