The year's second golf major is upon us.

The world's best golfers have descended on Erin Hills, the longest course in U.S. Open history. Thursday they'll tee off in hopes of raising the championship trophy Sunday night.

Before you enter a fantasy golf tournament -- like the $3.5 million fantasy golf Millionaire Maker on DraftKings -- you need to hear what Mike McClure has to say.

The predictive data engineer has well over $1 million in DFS winnings. He built SportsLine's predictive model, which called Sergio Garcia winning the Masters for his first major title in April.

McClure isn't high on Jordan Spieth (10/1), even though he opened as the second favorite behind Dustin Johnson. McClure has Spieth, shockingly, finishing outside the Top 10.

So when you fill out your fantasy lineup on DraftKings, avoid Spieth and his high price tag ($11,500).

One high-priced guy you'll want in your FanDuel or DraftKings DFS golf lineups is Rory McIlory. He opened at 12/1 to win the U.S. Open and is $11,200 in the Millionaire Maker. He took seventh in the Masters.

One value play you should get in: Kevin Kisner, who's just $7,500 on DraftKings. He won the Dean and Deluca Invitational in May. SportsLine's model pegs him for a ninth place finish this week.

McClure has a massive 30/1 long shot you'll want in all your DraftKings and FanDuel lineups. McClure says this long shot will be in contention Sunday, and he won't even set you back an arm and a leg in daily fantasy golf.

So who wins the 2017 U.S. Open? And what massive long shot stuns the golfing world? Visit SportsLine now to see the full U.S. Open leaderboard from the model that nailed the Masters.
