WEST DES MOINES, Iowa — The previous two years, Nick Price's final rounds at the Principal Charity Classic were filled with tough shots and even tougher finishes.

Price solved that problem Sunday by grabbing an early lead and never letting it go.

"Today was a big day for me, because I think had I not finished it off it would have left a psychological scar in me. Because I couldn't have played any better than I did this week," Price said. "I tried to be aggressive when I needed to. I tried to be conservative when I needed to."

Price shot a 4-under 67 to beat Tommy Armour III by four strokes for his second Champions Tour win of the year and third overall. The 53-year-old star, a three-time major champion, finished at 14-under 199 on the Glen Oaks Country Club course.

Price led heading into the final rounds the previous two years in Iowa before falling short. But Price grabbed the lead with a birdie on the fourth hole and stayed comfortably in front the rest of the way.

Armour, the co-leader with Price after two rounds, shot an even-par 71 and finished second for the third time this year. John Cook closed with a 66 to join Loren Roberts at 9-under 204, and six players finished at 8 under.
