PGA DFS players entering tournaments, cash games, or 50-50s on sites like FanDuel and DraftKings for the 2019 Houston Open have plenty of tough choices to make. Investing in Cameron Champ, Daniel Berger or Brian Harman could guarantee production, but all three come with hefty price tags. They'll eat up a large portion of your PGA DFS salary cap right off the bat, so making the right call on their value will be critical when evaluating the 2019 Houston Open PGA DFS slate. Before you enter any PGA DFS tournaments like the $250K Best Ball on DraftKings or the $45K PGA Eagle on FanDuel, check in with SportsLine's Mike McClure. He's a professional DFS player with almost $2 million in career winnings and his top picks, optimal lineups and PGA DFS advice can help you build the perfect roster.

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 A Military Tribute at the Greenbrier, McClure rostered Joaquin Niemann. The result: Niemann fired four rounds of 68 or under on his way to a score of 21-under and career-defining win. Anybody who had him in their lineup was well on their way to a huge weekend.

Now, McClure has set his sights on the 2019 Houston Open and revealed his optimal PGA DFS lineups. You can only see them at SportsLine.

One player McClure is rostering this week: Sebastian Munoz at $10,200 on FanDuel and $9,400 on DraftKings.

Munoz is an emerging star who has shown he has what it takes to compete with the best golfers on the PGA Tour. In fact, the 26-year-old won his first PGA Tour event earlier this year at the Sanderson Farms Championship. And he also finished inside the top 10 earlier this season at the Greenbrier Classic. 

Munoz enters this week's event hitting the ball extremely well off the tee, averaging 316.6 yards per drive this season. His ability to drive the ball deep into the fairway allows him to use his short irons to approach the green. That lethal combination has allowed Munoz to hit nearly 75 percent of greens in regulation, which has resulted in plenty of low scores. In fact, Munoz comes into the 2019 Houston Open ranked 10th on Tour in scoring average (69.402). His consistent play and low scoring average make him an extremely strong PGA DFS play this week.

McClure's optimal PGA DFS strategy also includes rostering Henrik Stenson at $11,900 on FanDuel and $11,400 on DraftKings.

Stenson's driving accuracy percentage makes him a strong play this week at the Houston Open. He finished last season ranked fifth on the PGA Tour in driving accuracy percentage, hitting over 72 percent of fairways off the tee. His ability to consistently find the fairway helped him over 65 percent of greens in regulation last season, which will result in more birdie opportunities and more chances to rack up points on sites like FanDuel and DraftKings. Lock him in your PGA DFS lineup and look for a tournament-winning return this week at the Houston Open.

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