Watch Now: Memorial Tournament Will Not Have Fans In Attendance (4:46)

The 2020 Workday Charity Open field is packed with stars, including three ranked among the top five in the world. But are Jon Rahm (No. 2), Justin Thomas (No. 4) and Brooks Koepka (No. 5) optimal plays for your PGA DFS lineup this week when the PGA Tour returns to Muirfield Village in Dublin, Ohio? Or should former major winners like Justin Rose, Phil Mickelson, Jordan Spieth and Patrick Reed be part of your PGA DFS strategy starting Thursday?

Thomas comes at a high price in the 2020 Workday Charity Open DFS player pool at $11,100 on DraftKings and $12,000 on FanDuel, so choosing him means you'll need to find value further down the board. Rahm isn't far behind at $10,900 on DraftKings and $11,800 on FanDuel. Before entering these PGA DFS tournaments or any others for the 2020 Workday Charity Open, you'll want to see the top PGA DFS picks, advice and player pool 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.

Last week at the Rocket Mortgage Classic, McClure was extremely high on Bryson DeChambeau. The result: DeChambeau shot 23-under par and finished on top of the crowded leaderboard, earning his first PGA Tour victory this season. Anybody who had him in their lineup was well on their way to a huge weekend.

Now, McClure has set his sights on this week's event 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 2020 Workday Charity Open.

Top Workday Charity Open PGA DFS picks

One of McClure's top PGA DFS picks for the Workday Charity Open 2020: Matthew Fitzpatrick at $8,000 on DraftKings and $9,700 on FanDuel. 

The 2013 U.S. Open champion, Fitzpatrick already has two top-10 finishes on his resume this season. Fitzpatrick finished seventh at the WGC-HSBC Champions and ninth at the Arnold Palmer Invitational, and most recently was 14th at the RBC Heritage. With five European Tour victories before his 25th birthday and having made the cut in his first outing at Muirfield Village last season, Fitzpatrick is primed for a breakout performance on the PGA Tour. Fitzpatrick is a steal at this price point, so lock him into your PGA DFS lineups and look for a big return this week at Muirfield Village.

McClure's optimal PGA DFS strategy also includes rostering Patrick Reed at $8,800 on DraftKings and $10,500 on FanDuel. 

Reed, who's finished in the top 10 five times this season, is an almost sure-fire bet to be near the top of the leaderboard come Sunday. Reed has been one of the best putters on tour, ranking fourth in strokes gained putting and first in one-putt percentage. He's also sixth on tour in birdie average (4.50), having racked up 189 of them in 42 rounds. Lock him in your PGA DFS lineup and look for a big return this week at the Workday Charity Open 2020.
