PGA DFS players entering tournaments, cash games, or 50-50s on FanDuel or DraftKings for the 2019 Safeway Open have plenty of tough choices to make. Investing in Patrick Cantlay, Adam Scott or Hideki Matsuyama is a great way to guarantee production, but all three come with a hefty price tag on both sites. They'll eat up a large portion of your PGA DFS salary cap right off the bat, so making the right call on the value of players such as them will be critical when evaluating the 2019 Safeway Open PGA DFS slate. And before you enter a PGA DFS tournament like the PGA Tour $250K Best Ball on DraftKings or the $50K PGA Eagle on FanDuel, first be sure to check in with 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 month at the Greenbrier Classic, McClure rostered Joaquin Niemann on FanDuel and DraftKings. The result: Niemann fired four rounds of 68 or under on his way to a score of 21-under and a first-place finish. 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 Safeway Open and has revealed his optimal PGA DFS lineups. You can only see them at SportsLine.

One player McClure is rostering this week: Collin Morikawa at $10,600 on FanDuel and $9,400 on DraftKings.

Morikawa 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 22-year-old finished inside the top five in three of his last six starts last season, which included his first-ever PGA Tour victory at the Barracuda Championship. Morikawa's success can be directly attributed to his greens in regulation percentage (71.88), which gives the youngster more makable 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 big return this week at the Safeway Open.

McClure's optimal PGA DFS strategy also includes rostering Justin Thomas at $12,200 on FanDuel and $11,600 on DraftKings.

Thomas enters his first event of the new season full of confidence after finishing inside the top 12 in five consecutive PGA Tour starts. The 10-time PGA Tour champion finished last season ranked sixth in greens in regulation percentage (70.68), fourth in eagles holes per (92.6), fifth in scoring average (69.466) and first in birdie average (4.58). Thomas' consistent play coupled with his low scoring average makes him an extremely strong PGA DFS play this week. 

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.
