He had to wait to see if it was the best score Thursday on a soft course in scorching conditions at the BMW Championship.

Woods and McIlroy had played a nine-hole practice round together on Tuesday.
It wasn't easy for everyone.
He drained the five-foot (1.5 metre) eagle putt and then added birdies at the 18th (his ninth), first and seventh before his first mistake of the day led to a bogey at the par-3 eighth.

But the longest putt he made on day two at Aronimink was six feet. "I'm not going to say it stings too bad because I'd much rather shoot 62 today and win the golf tournament Sunday than shoot 59 today and maybe not win".
