June 23 (Reuters) - A flawless Paul Casey hit every green in regulation to earn a four-stroke lead after the third round at the Travelers Championship in Connecticut on Saturday.
An eagle at the par-four 15th, where he sank a 20-foot putt, helped Casey to an eight-under-par 62 in benign conditions at TPC River Highlands in Cromwell.
The 40-year-old Englishman, in some of the most sparkling form of his career, posted a 16-under 194 total with one round left.
American Russell Henley shot 67 to move into second place on 12 under, as halfway leader Brian Harman (69) slipped back into a tie for third at 11 under with Anirban Lahiri of India (65) and American J.B. Holmes (65).
World number 13 Casey won the Valspar Championship on the PGA Tour in March, holding off Tiger Woods and Masters champion Patrick Reed by one stroke.
He performed solidly in the first two majors of the year, finishing in the top 16 at both the Masters and the U.S. Open. (Reporting by Andrew Both in Cary, North Carolina; Editing by Clare Fallon)
