The 2023 Open Championship will provide golf fans with star-studded groupings through the first two days of action. Jon Rahm will play alongside Rory McIlroy and Justin Rose when the 2023 Open Championship field opens play on Thursday from Royal Liverpool Golf Club. The 2023 Open Championship tee times feature this star-studded trio going off at 9:59 a.m. ET. Elsewhere in the 2023 Open Championship lineup, Scottie Scheffler, the No. 1-ranked player in the world, will be paired with Tommy Fleetwood and Adam Scott, a 14-time PGA Tour champion. McIlroy, who won the Open Championship the last time it was played at Royal Liverpool, is the +525 favorite in the latest 2023 Open Championship odds from Caesars Sportsbook.

Scheffler (+750), Rahm (+1200) and Rickie Fowler (+1200) round out the top four 2023 Open Championship favorites. Before locking in any 2023 Open Championship picks, make sure you see the PGA predictions and best bets from golf betting and fantasy expert Sia Nejad.

Nejad specializes in betting and DFS in golf, among other sports. He's had incredible success in the outright and first-round leader markets and in betting head-to-head matchups. The expert has been on fire on head-to-head matchups since the Charles Schwab Challenge, going 19-5-1 and returning 11.76 units over that span. That's a $1,176 profit for $100 bettors in the past eight weeks.

Nejad also nailed 75-1 longshot Wyndham Clark as the outright winner at the Wells Fargo Championship. In 2023, SportsLine debuted "The Early Wedge," and in the first three months of the show, he hit two first-round leaders and three outright winners. Nejad also had a winning head-to-head record in seven of nine weeks. He was up more than 70 units over that three-month span.

Now, Nejad has focused his attention on the 2023 Open Championship field and has locked in his best bets, top sleepers and favorites to avoid. See who they are at SportsLine.

Top 2023 Open Championship expert picks

One surprise: Nejad is low on the chances of Jon Rahm (+1200), even though he leads the FedEx Cup standings and is one of the top 2023 Open Championship favorites. Rahm has racked up 11 career victories on the PGA Tour, but he hasn't won a tournament since claiming the green jacket at the Masters in April.

The 28-year-old Spaniard has finished 50th or worse in two of his last four starts on the PGA Tour, which includes a missed cut at the Travelers Championship. Rahm ranks 99th in driving accuracy, which could spell trouble at Royal Liverpool. In addition, Rahm ranks 185th in scrambling from the rough (46.15%). "He is very capable of winning this tournament, but his recent form doesn't justify the short number, especially when you consider how well the top tier of talent is playing around him," Nejad told SportsLine. See who else to fade at SportsLine

However, Nejad is bullish on Dustin Johnson, even though he is a +3000 longshot. Johnson has been a bit off-the-radar since joining LIV in the summer of 2022. However, he has two wins and 11 top 10 finishes in 16 career LIV events.

Johnson will tee off in the Open Championship 2023 knowing his play is trending in the right direction. In his last three worldwide starts, Johnson has three top-10 finishes. "His form appears to be in good shape with back-to-back top 10 finishes, alongside a 10th at the U.S. Open," Nejad told SportsLine. See who else to pick at SportsLine.
