Top 10: Why each favorite will or won't win the U.S. Open

The 117th United States Open begins Thursday at Erin Hills Golf Club for the season's second major championship.

Here's a breakdown of the 10 favorites at the Open.

10. Adam Scott

Odds: 25-1

Best result: T4 in 2015

Why he'll win: The Aussie has length, a precise long game, and the right demeanor to navigate a United States Open setup.

Why he won't win: His short game and ability to scramble can let him down.

9. Sergio Garcia

Odds: 25-1

Best result: T3 in 2005

Why he'll win: The major drought is over for Sergio, thanks to his Masters triumph. The links-style course is a perfect setup for Garcia, with 10 top-10 results in the Open Championship.

Why he won't win: The Spaniard hasn't registered a top-10 result since his win at Augusta.

8. Hideki Matsuyama

Odds: 25-1

Best result: T10 in 2013

Why he'll win: Matsuyama is one of the best players with an iron in his hands, and had five wins in nine starts earlier in the season.

Why he won't win: He has zero top-10's since his win in Phoenix, and is ranked 180th in total putting.

7. Justin Rose

Odds: 20-1

Best result: Won in 2013

Why he'll win: Rose knows what it takes to win the trophy, and came so close to adding the Masters to his cabinet in April, losing to Garcia in a playoff.

Why he won't win: The Englishman hasn't won since 2015, and shot a final-round 80 at THE PLAYERS.

6. Rickie Fowler

Odds: 20-1

Best result: Runner-up in 2014

Why he'll win: Fowler is having a great 2017 season on tour, with a win and five top-10 finishes. The world No. 9 has length, accuracy, and has been putting well all year.

Why he won't win: The 28-year-old has never won a major, and has missed the last two cuts at the U.S. Open.

5. Jon Rahm

Odds: 15-1

Best result: (Low Amateur) T23 in 2016

Why he'll win: Rahm has length and the complete game to contend on any golf course, in any event.

Why he won't win: He showed at THE PLAYERS that his passion can get the better of him when receiving bad breaks.

4. Jason Day

Odds: 12-1

Best result: Runner-up in 2011 and 2013

Why he'll win: Day has proved he's got the game to win a major championship, holding off Jordan Spieth in 2015 for the PGA title.

Why he won't win: He owns just two top-10 results this season due to an inconsistent long game and putter.

3. Jordan Spieth

Odds: 12-1

Best result: Won in 2015

Why he'll win: Spieth is one of the few players that has played Erin Hills in a competitive environment, making it to the quarterfinals of the 2011 U.S. Amateur. Spieth can grind like no other player in the field, which is a major asset for the demands of the U.S. Open.

Why he won't win: His putter hasn't been as sharp this season.

2. Rory McIlroy

Odds: 12-1

Best result: Won in 2011

Why he'll win: McIlroy is one of the best players in the game tee to green.

Why he won't win: The world No. 2 hasn't played much in 2017 due to a rib injury.

1. Dustin Johnson

Odds: 13-2

Best result: Won in 2016

Why he'll win: Johnson is the world No. 1 with three tour wins this season.

Why he won't win: He missed the cut in his last start at the Memorial.
