Robert Allenby's eventful week in Miami continued when a hole-in-one took him back into a tie at the top alongside clubhouse leader Ernie Els at the World Golf Championships-CA Championship before play was suspended due to bad weather.
On the opening day Allenby pitched in for an eagle and had six birdies to stand eight under par and four clear after 12 holes, only to bogey the final four holes.
His ace came with a 233 yard fairway wood at the short 13th, his fourth of the day, and further birdies at the tenth and 14th took the Melbourne golfer to eight under again.
This time he shared top spot with South Africans Charl Schwartzel and Els, but on the 372 yard 16th Allenby drove into sand, duffed a pitch into another bunker and then missed from under four feet.
Second round tee-off times in the WGC-CA Championship had been brought forward nearly three and a half hours because of the threat of thunderstorms and Els birdied four of his first seven holes.
Compatriot Schwartzel, the overnight pacesetter following a 67, resumed with a ten foot eagle putt at the long first and then birdied the fifth.
The 25 year old, twice a winner in his home country already this year, had been the only player in the 68-strong field not to drop a shot on day one and he remained bogey-free after 24 holes.
Allenby's rollercoaster ride continued as he followed a birdie on the second with a bogey at the next.
Els reached the clubhouse ten under par as he searches for a first win since the 2008 Honda Classic.
“I'm just pleased we got it done,” he said after his 66. “The weather is changing a lot. We played the last three holes very fast to get done. I'm in pretty good shape, I'm playing okay.”
America’s Bill Haas was next best in the clubhouse at seven under, ahead of Dane Søren Hansen and Ireland’s Padraig Harrington.
“Playing really well and hitting a lot of greens,” said Hansen. “Giving myself a lot of chances and I suppose that's what it's all about in this game.”
