PGA DFS players will have a star-studded field to choose from this week at the 2021 AT&T Byron Nelson. With big names like Jordan Spieth, Bryson DeChambeau, Brooks Koepka and Hideki Matsuyama among the most expensive players on both FanDuel and DraftKings, you'll want to identify the golfers who present the best value before entering your PGA DFS lineups for the AT&T Byron Nelson 2021. That will help you afford more expensive, less risky PGA DFS picks like Spieth, who's finished inside the top-five in five of his last seven starts on the PGA Tour.

FanDuel is hosting a $125k PGA Eagle and DraftKings is offering a $750k Flop Shot that awards $200k to the winner, which means there will be some difficult decisions when crafting your PGA DFS strategy. Before you enter these PGA DFS tournaments or any others for the 2021 AT&T Byron Nelson, you'll want to see the top PGA DFS picks and daily Fantasy golf advice from SportsLine's Mike McClure.

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.

Last week at the Wells Fargo Championship, McClure included Viktor Hovland as one of his top PGA DFS picks. The result: Hovland secured a third-place finish, returning over 95 points on FanDuel. Anybody who had him in their lineup was well on the way to a profitable weekend.

In addition, McClure's model is up almost $10,000 on its best bets since the restart, nailing tournament after tournament. This is the same model that has nailed a whopping six majors entering the weekend. Anyone who has followed it has seen massive returns.

Now, McClure has set his sights on the 2021 AT&T Byron Nelson and revealed his optimal PGA DFS advice, strategy and player pool. Head to SportsLine now to see his top daily Fantasy golf picks for the 2021 AT&T Byron Nelson.

Top 2021 AT&T Byron Nelson PGA DFS picks

One of McClure's top PGA DFS picks for the AT&T Byron Nelson 2021 is Carlos Ortiz at $7,800 on DraftKings and $9,900 on FanDuel. The 30-year-old's price tag makes him an extremely affordable piece for PGA DFS rosters this week. That's because Ortiz has been playing extremely well this season. In fact, Ortiz secured his first career victory on the PGA Tour at the Vivint Houston Open, and he's finished T-15 or better five times already this season. 

In addition, Ortiz is one of the most consistent putters on tour, ranking inside the top-25 in putting average (1.725), overall putting average (1.574) and three-putt avoidance (2.08). He's a complete steal at this price point, so lock him in your PGA DFS lineups and look for a big return at TPC Craig Ranch.

McClure's optimal PGA DFS strategy also includes rostering Jon Rahm at $11,000 on DraftKings and $12,200 on FanDuel. 

Rahm, who's finished inside the top-10 in nine of his last 12 PGA Tour events, is an almost sure-fire bet to be near the top of the leaderboard come Sunday. The 26-year-old has been extremely consistent this season, and he'll enter this week's event ranked fifth on the PGA Tour in greens in regulation percentage (72.22) and ninth in scoring average (69.960), which makes him an extremely valuable PGA DFS asset.
