Cox/Getty ImagesScheffler hit every single fairway on day two of the RBC Heritage at Harbour Town Links on Friday.The world number one is driving the ball to a very high level once again, and he’s now ranked 11th in strokes gained off the tee this season.Meanwhile, Scheffler’s putting has been very good all year long, and he’s ranked 16th in strokes gained on the greens in 2026.However, his iron play has been incredibly poor by his standards.Scottie Scheffler is close to figuring out his iron playThe man from Dallas, Texas, is ranked 81st in strokes gained approach so far this season, having topped the rankings in that category over the past three years.However, there are signs that he is close to rediscovering his very best iron play.He gained more than five strokes on the field with his approach play on Saturday at The Masters last week, and he has been very solid with his irons this week on Hilton Head Island.He is back inside the top 35 for strokes gained approach during the first two rounds at the RBC Heritage.While that doesn’t sound great for a player of Scheffler’s calibre, it represents a huge improvement on what he has served up with his irons so far this season.It won’t be long before everything clicks once again and he starts taking out flagsticks on a regular basis.If Scheffler continues to make small improvements in his approach play, even if he manages to get inside the top 20 for strokes gained approach, he will be an absolute menace on the PGA Tour once again.
