SOUTHPORT, England (AP) - Jordan Spieth will take a three-shot lead into the final round of the British Open.

Spieth is three clear of Matt Kuchar. He widened his lead on the final hole, sinking a birdie putt from the edge of the green, while Kuchar missed one that was closer.

Spieth separated himself from the field with a third-round 65, matching his score from the first round. Kuchar, playing in the same final group, shot a 66.

U.S. Open champion Brooks Koepka was six shots back, tied with Canadian Austin Connelly. Branden Grace was another shot back after shooting a major championship record 62.

Spieth, who has won the Masters and U.S. Open, is trying for his first British Open title. Kuchar has yet to win a major championship.
