Justin Rose is going into the final round with another big lead on the PGA Tour.

Rose made some critical par saves in the middle of his round Saturday and wound up with a 3-under 67 to build a four-shot lead over Carl Pettersson and Charlie Wi in the AT&T National.

A week ago at the Travelers Championship, Rose had a three-shot lead going to the last round until he crumbled on the back nine. Rose says he has learned from his mistakes, and he'll get to put those lessons to use on Sunday.

Tiger Woods completed another round of 70 as the leaders were finishing lunch. He was tied for 47th and was 13 shots behind, making this the longest drought without winning in six years.
