The third round of the 2018 British Open gets underway at 4:15 a.m. ET on Saturday morning. Kevin Kisner and Zach Johnson are the co-leaders at 6-under heading into the weekend, but dozens of players are still within striking distance at golf's third major. Daily Fantasy sports sites FanDuel and DraftKings are offering weekend tournament, and before setting your PGA DFS lineups on either site, you'll want to see what Mike McClure has to say. McClure is a DFS pro with almost $2 million in career winnings, and he's had some spot-on picks in golf DFS this year.

For the full weekend British Open tournament, McClure locked in Alex Noren as a value play at $8,300 on DraftKings and $9,800 on FanDuel. The result? Noren heads into the weekend very much in contention as he sits inside the top 20 with a score of 1-under par through two rounds. Anybody who had him in their lineup was well on their way to a profitable weekend.

Now McClure has set his sights on the 2018 Open Championship weekend and revealed his optimal DFS lineups. He is only sharing them at SportsLine.

One player McClure likes for weekend British Open tournaments: Patrick Reed, who is $7,600 on DraftKings and $11,400 on FanDuel. 

Reed, the 2018 Masters champion, snuck in under the cut line with a 3-over par through two rounds at the British Open 2018. But after a shaky start on Thursday, he settled in with a 70 in Round 2 on Friday, meaning he'll carry some confidence and momentum into the weekend. He's shown the ability to play well in the majors, so lock him in at an affordable price and watch the birdies roll in.

Another pick McClure likes for the weekend: Tommy Fleetwood, who is $9,000 on DraftKings and $10,900 on FanDuel.

Fleetwood enters Saturday 5-under after surging in the second round with a score of 65, pushing for the course record of 63 which he also owns. He's playing extremely well and has a great chance to win it all this weekend, so he's a pick you should be all over.

McClure is also targeting multiple value picks you're not even thinking about that will allow you to build a loaded roster with huge potential. Picks like these could be the difference between winning your DFS contests or going home with nothing.
