The 2019 Wimbledon men's quarterfinals get underway on Wednesday morning at 8 a.m. ET. Novak Djokovic vs. David Goffin, Roberto Bautista Agut vs. Guido Pella, Rafael Nadal vs. Sam Querrey and Roger Federer vs. Kei Nishikori are the four matches on the Wimbledon schedule, and daily Fantasy sites like FanDuel and DraftKings are running big-time cash games and tournaments for this quarterfinal slate. A few of these matchups look lopsided on paper, but that also presents potentially huge DFS values. So before locking in any tennis DFS picks of your own for Wednesday, July 10, you should see the optimal Wimbledon DFS lineups and advice for the men's quarterfinals from SportsLine's Mike McClure, a DFS pro who has won almost $2 million in his career.

He's cashed huge in tournaments in multiple sports in the past year, and now his proprietary tennis DFS projection model, which has simulated every match, has zeroed in on the 2019 Wimbledon men's quarterfinals and revealed top picks and optimal lineups.

We can tell you one of McClure's top tennis DFS picks for Wednesday is Nadal, the No. 3 seed who takes on Querrey, an unseeded American, at 10 a.m. ET. Querrey stunned No. 5 Dominic Thiem in the first round and then took down Aubrey Rublev and John Millman in straight sets in the next two rounds before grinding his way to a hard-fought victory over Tennys Sandgren in the fourth round. 

But while he's been impressive, Nadal has won three of his Wimbledon matches in straight sets thus far. In those three matches, none of his opponents had more than three games in any set. The two-time Wimbledon and 18-time major champion should overwhelm Querrey, according to McClure's model, and is a top Wimbledon DFS pick on Wednesday.

Part of his optimal Wimbledon DFS strategy for Wednesday also includes rostering Pella, the No. 26 seed who has already pulled off upsets against No. 4 Kevin Anderson and No. 15 Milos Raonic at Wimbledon. He showed great determination in coming back from an 0-2 set deficit against Raonic in the prior round. McClure's model is high on his chances to return value as he takes on Bautista Agut, a player also appearing in the Wimbledon quarterfinals for the first time in his career. 

McClure is also targeting an undervalued player who is set to explode for huge numbers on Wednesday. The stars are aligning for him to return plenty of value and he comes at a price that won't break the bank. This pick could be the difference between cashing in big or going home with nothing.

So what 2019 Wimbledon men's quarterfinals lineup should you enter on Wednesday? And which undervalued player is a must-roster?
