Not bad for a guy who insists he was "outplayed" by Huston for most of the day by Huston before the final five holes.
Now Couples heads into Sunday searching for his third major title since joining the Champions Tour in 2010. He won the Senior Players in 2011 at Westchester Country Club in New York and the Senior British Open last year. He was in position to capture the Regions Tradition earlier this month but fell one shot short in a showdown with points leader David Frost.
This time it appears the duel will be with Perry, who is pain-free after dealing with knee problems earlier in the season.
Perry, who has undergone surgery on both knees during his career and takes medicine to deal with arthritis in the joints, called his recovery over the last two weeks "a miracle." He took a cortisone shot in his left knee recently and has had fluid drained out of the joint, freeing him up to walk the course with relative ease.
"If you have had a need this long stuck in your knee with a big syringe sucking all that junk out of you, that's not very pleasant," Perry said. "But once they do it, immediately it gives you relief. The pressure's off and you can actually bend your knee, you can actually walk."
Perry will walk alongside Couples on Sunday as Perry looks for the first major title of his 31-year professional career.
"You're going to see still a lot of good scores tomorrow," Perry said. "So the guys that are near the lead, at the lead are going to have to play a good round of golf. Somebody's going to have to shoot a good round tomorrow."
