Dunne and Harrington hopes fade in final round
Padraig Harrington and Paul Dunne both fell away after frustrating final rounds on the European and PGA Tours.
Harrington was tied for sixth at the Valero Texas Open after a third round of 68. Any hopes of a final round charge up the leaderboard were effectively dashed by consecutive bogeys at the third and fourth holes.
A birdie at the par five eighth gave him a sliver of hope, but he dropped a shot on the next hole to turn in 38, two over for his round, and heading in the wrong direction. An even par back nine left him tied for 25th in the tournament.
There was joy, however, for Charley Hoffman who birdied the final hole to snatch victory from Patrick Reed.
The pair looked set to be heading for a play-off when Hoffman found the greenside bunker on the 18th.
But his chip managed to just find the green and he holed a 10-foot putt to take victory.
Both Hoffman and Reed shot final rounds of 69 as did third placed Chad Collins while overnight leader Ricky Barnes tumbled down the leaderboard.
Dunne endured a similar final round to his compatriot as three bogeys and an inability to find any birdies cost him any chance of challenging at the Shenzhen International.
Soomin Lee, Alexander Levy and Lee Slattery were in a three-way tie for the lead when play was suspended for the day due to bad weather.
More than six and a half hours had already been lost to bad weather over the first two days at the Genzon Golf Club when an afternoon thunderstorm ensured that 23 players - including Dunne - would have to return early on today to complete their rounds.
The leading trio were on the back nine when play was suspended with South Korean Lee, seeking his first European Tour win, and Englishman Slattery having completed 13 holes.
Dunne had two holes remaining while lying in 25th position.
