Padraig Harrington had to settle for a share of 13th place in his final warm-up for the US Open starting on Thursday.

Harrington closed to only one stroke off the lead with four birdies in the first seven holes of the delayed final round at the US Tour's Capital Open in Maryland.

But then came a bogey at the eighth, a double bogey two holes later and further bogeys at the 12th and 14th.

That ended the Dubliner's title hopes, but the roller-coaster ride continued with a birdie at the 16th and closing bogey for a one over par 72 and six under aggregate of 278.

South African Rory Sabbatini enjoyed his second US Tour victory at 14 under, beating Duffy Waldorf by two strokes and Joe Durant by four.

Bernhard Langer finished joint fifth, Swede Niclas Fasth - second with a round to go - seventh and Scotland's Paul Lawrie 42nd following a 77 that contained a quadruple bogey eight at the fourth and, like Harrington, a six at the 10th.

Final round scores from the FBR Capital Open at TPC at Avenel, Potomac, Maryland (USA unless stated, par 71)
