Before you set your PGA DFS lineups on sites like DraftKings and FanDuel for the 2019 Hero World Challenge, you need to hear what SportsLine's Mike McClure has to say. 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.

Earlier this season at the CJ Cup at Nine Bridges, McClure rostered Justin Thomas on FanDuel. The result: Thomas fired three rounds of 68 or under on his way to a score of 20-under par while earning his 11th career PGA Tour victory. Anybody who had him in their lineup was well on their way to a huge weekend.

Now, McClure has set his sights on Wednesday's Hero World Challenge 2019 and revealed his optimal PGA DFS lineups. You can only see them at SportsLine.

We can tell you McClure is rosteringWebb Simpson at $8,800 on FanDuel and DraftKings. Simpson enters this week's event full of confidence, having finished inside the top 10 in both of his PGA Tour starts this season. The five-time PGA Tour champion's driving accuracy percentage is what makes him a strong PGA DFS play this week at the Albany Golf Club in the Bahamas. In fact, Simpson is hitting over 72 percent of fairways off the tee, and his ability to consistently find the fairway has helped him hit over 80 percent of greens in regulation this season.

McClure's optimal PGA DFS strategy also includes rostering Jon Rahm at $11,500 on FanDuel, $11,200 on DraftKings. 

Rahm, the defending champion of this event, finished last season ranked sixth in scoring average (69.618) and birdie average (4.35). His familiarity with the course at Albany Golf Club and sky-high upside make him an extremely strong daily Fantasy golf pick at the Hero World Challenge 2019. 

McClure is also targeting an undervalued player who's primed to blow up this week, giving you a huge return on both sites. Picks like these could be the difference between winning your PGA DFS contests or going home with nothing.
