The first of golf's four majors is just hours away, as the 2021 Masters begins Thursday at the iconic Augusta National Golf Club. Though you can't win a green jacket, you can compete in DraftKings' $4M Fantasy Golf Millionaire contest and FanDuel's $1M PGA MEGA Eagle tournament. Winning 2021 Masters DFS tournaments means entering optimal PGA DFS lineups, including choosing between favorites like defending champion Dustin Johnson, defending U.S. Open champ Bryson DeChambeau and recent Players Championship victor Justin Thomas.

Johnson will set you back $11,500 on DraftKings and $12,100 on FanDuel, so rostering him means finding value further down the 2021 Masters DFS player pool. Before you enter any PGA DFS tournaments or cash games for the 2021 Masters Tournament, you'll want to see the top PGA DFS picks and daily fantasy golf advice from SportsLine's Mike McClure.

McClure is a DFS pro with nearly $2 million in career winnings, and he's been red-hot on his PGA Tour picks this season. McClure is also a predictive data engineer at SportsLine who uses a powerful prediction model that simulates every tournament 10,000 times, taking factors like statistical trends, past results and current form into account. This allows him to find the best PGA DFS values and create optimal lineups that he shares only over at SportsLine. They're a must-see for any PGA DFS player.

At the Honda Classic in March, McClure listed Denny McCarthy among his top PGA DFS picks. The result: McCarthy secured a third-place finish, returning tournament-winning value at an extremely affordable price. Anybody who had him in their lineups was well on the way to a profitable weekend.  

In addition, McClure's model is up nearly $10,000 on its best bets since the restart, nailing tournament after tournament. This is the same model that has nailed a whopping six majors entering the weekend, including Patrick Reed's historic victory at Augusta National in 2018. Anyone who has followed it has seen massive returns.

Now, McClure has set his sights on the 2021 Masters Tournament and revealed his optimal PGA DFS advice, strategy and player pool. Head to SportsLine now to see his top daily fantasy golf picks for the 2021 Masters.

Top 2021 Masters PGA DFS picks

One of McClure's top PGA DFS picks for the Masters 2021: Corey Conners at $6,900 on DraftKings and $8,900 on FanDuel. The 2019 Valero Texas Open champion, Conners is in the 2021 Masters field due to his 10th-place finish last November.

Conners was the first Monday qualifier to win on the PGA Tour since Arjun Atwal did it during the 2010 Wyndham Championship and became the final qualifier for the 2020 Masters. Conners then parlayed that entry into a steady performance last November, carding a second-round 65 and then playing the second nine on Sunday in 33 to finish with a final-round 69. A player eager to taste victory who has performed well at Augusta National, Conners should be part of your PGA DFS strategy at the Masters 2021, according to McClure.

McClure's optimal PGA DFS strategy also includes rostering Collin Morikawa at $9,600 on DraftKings and $11,000 on FanDuel. The 24-year-old made his first 22 cuts as a pro, the second-longest streak over the last 30 years, trailing only Tiger Woods' 25 straight.

Morikawa's composure is evident when approaching the green because there is no one better. His 1.238 strokes gained on approach leads the PGA Tour, while his greens-in-regulation percentage of 72.53 percent ranks fifth. Already with a win in 2021, as well as two other top-10 finishes, look for Collin Morikawa to make a strong run at the Masters 2021, making him one of the top choices for your PGA DFS strategy.
