We outline many new-user offers for big events, but what about existing users? They need some love, too.

We've compiled 10 promos and bonuses for the 2023 U.S. Open that all users can bet. Some are auto plays, like bet365's Jordan Spieth to make the cut at +100, while others are clear passes, like Caesars' Dustin Johnson and Brooks Koepka to finish top-20 at +350.

1. FanDuel (2 promos)

  • Offer 1: Bet a golfer outright, get bonus bets back if he finishes top-20

FanDuel has run these promos before for golf majors. You can bet on any golfer to win the tournament, and if he finishes in the top 20, you'll get refunded in bonus bets. The max you can bet for the insurance varies, from $10 (most likely for most people) to $250 (per the terms).

Although the price has come down, FanDuel was dealing a good number on Scottie Scheffler at +700 earlier in the week; it's now down to +600. It's been 16 tournaments since he finished outside the top 20, and he's playing by far the best golf in the world right now. He's been second and T-7 in the last two U.S. Opens.

  • Offer 2: Hovland, Rahm and Mickelson to all make the cut, +350

This is a pretty straightforward boost — we just need to get the "true" prices of each player to make the cut, parlay them together, and compare it to the boosted price of +350.

Using Circa Sports' odds to make/miss the cut, the price comes out to +307, making the boosted price to +350 about 10% EV and worth betting. It's probably slightly less since only so many players make the cut, and two of these players making it lowers the chance of the other one making the weekend.

Pick: Hovland, Rahm, Phil to make the cut, +350

What is QuickSlip?

QuickSlip is an Action Network feature that allows users to automatically pre-load their bet slip at FanDuel Sportsbook.

2. DraftKings (3 promos)

  • Offer 1: +300 odds surge on any golfer to win

DraftKings has introduced this new concept called an "odds surge," which allows you to add American odds to a golfer to win a tournament (and other markets at times).

Sportsbooks have typically offered "profit boosts" in the past. These boosts will increase your payout by a proportional amount no matter what price you're betting.

Say you have a 25% profit boost for a golf tournament. Here's how the lines would change:

  • A +400 bet becomes +500
  • And +4000 becomes +5000

But in that same scenario, with an odds surge of +300 like DK is offering for the U.S. Open, you'd be going from…

  • +400 to +700
  • And +4000 to +4300

These are not equal changes — the +400 to +700 is a much bigger jump in probability. So like some of these other promos, Scottie Scheffler makes sense here.

If his true odds are +666 (per DataGolf) and you're getting him at +900 at DraftKings, that's 30% EV.

With almost all of these odds surges, it makes sense to play the favorites if you're going to use them.

  • Offer 2: McIlroy, Hovland, Koepka and Thomas to make the cut, +125

The true price of this is +185, so statistically, it's a pass at only +125.

  • Offer 3: A Hole-in-one any time in the tournament, boosted to +100

There haven't been many too many hole-in-ones in U.S. Open history, but bet365 (-143) and FanDuel (-126) both think it's more likely than not that there's one in 2023. Comparing those prices to the DK boost at +100 makes it worth playing.

There are some absurdly long par-3s at LA Country Club, but one is expected to play about 124 yards, which will be the best opportunity.

3. bet365 (2 promos)

  • Offer 1: Spieth to make the cut, (super) boosted to +100

Circa has the true price of Spieth to make the cut at -313, so +100 here is a must-play at north of 50% EV. Some states may have other players — I saw Nick Taylor at +150, which would also be a clear play. DataGolf has him at -131 to make the cut coming off his win last week.

  • Offer 2: 25% profit boost on any outright bet

Boost your outright bet by 25%. That means you can take Scheffler from +600 to +750, or Xander Schauffele from +1800 to +2250, for example. bet365 has two of the better prices available on Schauffele and Patrick Cantlay, making them good choices for this promo.

4. Caesars (2 promos)

Both of these boosts are pretty terrible, but if you want to bet any of these players anyway, go for it.

  • Offer 1: Dustin Johnson & Brooks Koepka to finish top-20, +350

Using DataGolf's projections, the true price of Koepka and Dustin Johnson finishing top 20 is +740, so this boost is quite bad. Add in the fact that ties are losses (so if DJ finishes T-19 with four other players, you'd lose), and it's even worse.

  • Offer 2: Schauffele & Homa to finish top-10, +1200

Same thing here — the true price of this is north of +2300, making the "boost" to +1200 quite bad.

5. Barstool (1 promo)

  • Offer: Bet $25 on up to three players to win the U.S. Open, get 50% back if they finish 2nd-5th, or 25% back if they finish 6th-10th

This isn't a great offer in a vacuum, but if you bet regularly at Barstool Sportsbook and want to bet the U.S. Open anyway, it may be worth it for you. So, if you bet $20 on Brooks Koepka to win and he finishes T3, you'll get $10 back in bonus bets. If you bet $20 on Dustin Johnson to win and he finishes T9, you'll get $5 back.

Barstool has relatively strong pricing on Schauffele, Sungjae Im and Hideki Matsuyama.
