I'm a bit surprised at the results after day one. DeChambeau being the biggest one sharing the lead at -6. Lefty -5, Langer -1, Weir - even par...the old guys seem to be faring well. Meanwhile Paul Casey who has been a fixture on the Masters leaderboard the past few years had a horrible round and sits in second last place with +9. Other leaderboard stalwarts McIlroy +1 and J Rose +3 didn't fare well on day one. But certainly can't count these guys out given their recent track record at Augusta.
