Johnson put the seal on his great day with an eagle at the final hole of round two. It was a remarkable effort for the 28 year old as although the conditions had improved considerably from those which caused play to be canned on the opening three days, the winds were still very strong.
"I played really well," said Johnson stating the obvious. "Just the three 3"‘putts, could have been a little bit lower. I hit the ball really well. I only missed one green and in this wind, that's pretty good. Drove it pretty well, too. Just it's really tough once you get on the green. I had three 3"‘putts, but other than that, I played really solid. I made some short ones but you know, it's just tough to read them and with this much wind, you've got a right"‘to"‘left putt and the wind is coming off the left and you're playing outside left, that's tough.
"I came out early more just to practice for myself. I had new equipment, new driver, new irons, so needed to play with those. I just needed to play because I had taken two weeks off."
Defending champion Steve Stricker recovered from a slow opening to his tournament to record a second round of 67 and keep his chances of a successful defence alive.
Stricker would also eagle the 18th in round two but for him it was his 9th hole, the field divided into a two tee start to ensure play was completed on time.
Bubba Watson is in 3rd position one shot behind Stricker.
Marc Leishman is the only Australian in the field and he sits at 4 over par and in 27th position in the 30 man field.
