Paul Casey heads to the 2021 Valspar Championship looking to defend his title starting on Thursday, but should the two-time defending champion be included in your PGA DFS lineups this week? With a 2021 Valspar Championship field that features the likes of Justin Thomas, Dustin Johnson, Patrick Reed and Justin Rose, Casey will have his hands full if he wants to three-peat. Casey has finished inside the top-10 in four of his last seven starts, but he enters the Valspar Championship 2021 having failed to crack the top-25 in each of his last three events. 

Casey is listed at $10,000 on DraftKings and $11,400 on FanDuel, so rostering him means finding plenty of value elsewhere in the 2021 Valspar Championship PGA DFS player pool. Should Casey be part of your PGA DFS strategy, or should you look elsewhere when finalizing your PGA DFS picks? Before you enter any PGA DFS tournaments or cash games for the 2021 Valspar Championship, you'll want to see the top PGA DFS picks and daily fantasy golf advice from SportsLine's Mike McClure.

Top 2021 Valspar Championship PGA DFS picks

One of McClure's top PGA DFS picks for the Valspar Championship 2021: Tyrrell Hatton at $9,400 on DraftKings and $11,100 on FanDuel. Hatton missed the cut at the Valspar Championship in 2019, but the eighth-ranked player in the world enters this week's event ranked inside the top-25 in a number of important statistical categories, which will help return solid value for your PGA DFS lineups at the 2021 Valspar Championship. 

He ranks sixth in strokes gained: approach the green (.905), 12th in sand save percentage (61.22) and 23rd in strokes gained: tee-to-green (.977). Hatton also ranks inside the top-30 in putting average (1.724), total putting (137.3) and 3-putt avoidance (1.72). Hatton is one of the most consistent putters on tour, and McClure recommends you lock him in your PGA DFS lineups and look for a big return this week at Innisbrook.

McClure's optimal PGA DFS strategy also includes rostering Ryan Palmer at $8,500 on DraftKings and $10,000 on FanDuel. Palmer's price tag makes him an extremely affordable piece for PGA DFS lineups this week. That's because Palmer has been playing extremely well in his most recent outings. In fact, the 44-year-old has finished T-17 or better in five of his last eight starts, which includes a runner-up finish at the Farmers Insurance Open. 

In addition, Palmer ranks inside the top-20 in greens in regulation percentage (69.56), birdie average (4.38) and strokes gained: approach the green (.581). Palmer has all the tools needed to make a deep run at Innisbrook, making him a great choice for 2021 Valspar Championship PGA DFS lineups.
