With a final-round 61, William Mouw captured his maiden TOUR victory at the ISCO Championship. Mouw began Sunday seven strokes behind and shot a career-low round to win by one stroke over third-round leader Paul Peterson. But coming from behind wasn't the only unconventional thing about his victory. Mouw uses 15-year-old Ping Anser irons.
