MAYNOOTH, Ireland — England's Paul Casey sensationally eagled the last hole to end a two-year victory drought and capture the Irish Open at Carton House, Maynooth, Sunday. The 35-year-old came from four shots behind at the start of the final round to win by three shots with a six-under-par score of 66 for a 14-under par total. It is his first win since winning the 2011 event in Bahrain. England's Robert Rock (71) birdied the closing two holes to share runner-up spot with Joost Luiten of the Netherlands — it was the second time in four years the Englishman had filled that position in the event. Park leads US Open In New York, Inbee Park is one round from making history by winning the first three majors of the year. The top-ranked Park had a four-stroke lead through three rounds at the US Women's Open. She shot 1-under 71 in harsh conditions at Sebonack and was 10 under for the tournament Saturday. Fellow South Korean I.K. Kim had a 73 to remain in second but lost two strokes to Park. With the wind whipping, the greens fast and the pin placements tricky, Park was the only player to shoot under par for the round. No one has ever won the first three majors in a year when there were at least four. England's Jodi Ewart Shadoff (74) was third at 3 under. She had to play 21 holes Saturday after the second round was suspended the night before because of fog. Park had good timing Friday: Her group was on the 18th fairway when the horn sounded, so she was able to finish off her round and rest up for the weekend. Four-way tie A tumultuous day at the AT&T National ended with a four-way tie for the lead heading into Sunday's final round at Congressional Country Club in Bethesda, Maryland. Roberto Castro chipped in from 80 feet after hitting his approach into the water to save par at the 18th and complete a 71 to join the group at seven-under-par 206 along with Andres Romero of Argentina, and Americans Bill Haas and James Driscoll. Long-hitting Jason Kokrak, who powered a 349-yard drive at 18 on his way to finishing a 70 for 207, one stroke better than Tom Gillis and South Korea's Charlie Wi. Wi made nine birdies, including seven on the front nine, on his way to a 65. Jordan Spieth took an early two-shot advantage after opening the round with two birdies to reach nine under par before he slipped back to four under, three off the pace. — Agencies
