Summary Holmes, seeking his fourth career US PGA title, birdied the 14th through 17th holes.
MIAMI (AFP) - J.B. Holmes fired a hole-in-one and birdied four of the last five holes to seize a five-stroke lead after Saturday s third round of the World Golf Championships event at Doral.
Holmes, seeking his fourth career US PGA title, birdied the 14th through 17th holes before a closing bogey as he fired a two-under 70 to stand on 11-under 205 after 54 holes in the Cadillac Championship.
Reigning Masters champion Bubba Watson blasted a bunker shot 43 feet for a birdie to finish his round of 70 and grab a share of second with fellow American Dustin Johnson on 210 with compatriot Ryan Moore fourth on 211.
Johnson aced the par-3 fourth hole only to have Holmes match his feat about 20 minutes later, both of them using 7-irons to solve the 227-yard hole.
There had not been an ace on the hole in 25 years.
South African Louis Oosthuizen, Swede Henrik Stenson and American Bill Haas were on 212 with England s Lee Westwood, Australian Adam Scott, Spain s Sergio Garcia and American Webb Simpson on 213.
Holmes, whose first PGA title since 2008 came last year at Quail Hollow, opened Thursday with a stunning 62 and followed with a 73 Friday despite finding the water four times.
Holmes opened with a bogey and sandwiched another at the seventh around his ace at the fourth. He took another bogey at 12 but responded with birdie putts from 12 feet at the 14th, 15th and 17th.
At 16, Holmes put his tee shot into a greenside bunker but blasted out inches from the cup to set up a tap-in birdie.
But his tee shot at 18 sailed way right and he ran over the edge of the cup on a 25-foot par putt.
Watson seeks his eighth title and second victory since last year s Masters, having already taken the WGC HSBC Champions last November.
Johnson seeks his ninth PGA triumph, his first since the 2013 WGC HSBC Champions.
