Scott birdied his first four holes and then battled the revamped TPC-Four Seasons golf course and the blustery winds for the rest of the day.
"It was a fast start, which was very handy this morning," Scott said. "But after that it was a bit of a battle, a fair bit of scrambling going on. The conditions were tricky. It was hard to hit fairways and hard to hit greens, hard to hit it close."
Trevor Immelman, playing for the first time since winning the Masters this month, shot a 75 and missed the cut by 10 strokes.
