AUGUSTA, Ga. (AP) – A look at the key hole in Thursday’s first round of the Masters:

Hole: 13.

Yardage: 510 yards.

Par: 5.

Stroke average: 4.67.

Rank: 18.

Key fact: The easiest hole on the course, this par-5 played tough for Tiger Woods. He was looking at a possible eagle after a 4-iron to the green, but the ball rolled over the back edge and he flubbed a chip on his way to a bogey 6. Justin Rose made the last of his six birdies here to take the lead he shared after the first round with Trevor Immelman.
