New Zealand teenager Lydia Ko took time to wake up but there was nothing sleepy about the way she opened her defence of the Canadian Open golf championship[.
The world's top amateur, who had a 7am tee time, carded a five-under-pa 65 to be in a three-way tie for the lead after day one in Edmonton.
"When I tried to wake up this morning, my eyelids weren't coming up," she said.
"I said, oh, my God, I'm just tired. But after you've woken up, you're fine, you're ready to go."
The 16-year-old went on to reel off five birdies in her opening 10 holes at Royal Mayfair. There was another birdie on the 14th, before her only bogey at the 15th.
She finished level with world No.16 Angela Stanford of the United States and Dutchwoman Christel Boeljon, who had a hole-in-one late in her round.
The three are one stroke clear of Americans Christie Kerr and Paula Creamer, with world No.1 Inbee Park of South Korea another shot back.
"Up to the seventh hole I went birdie, par, birdie, par, that kind of pattern," Ko said.
"Yeah, I wouldn't mind the colour ratio on my scorecard if I looked on the computer. I played pretty solid today."
World No.19 Ko was at her ball-striking best.
She hit her approach on the par-five third to tap-in distance, while the rest of her birdie putts were "just reasonable distances, not extremely long or extremely short".
Last year, when she took the title in Vancouver at 15, she created international headlines by being the youngest winner of an LPGA event.
She admitted it was different coming into an event with a world-class field as the title-holder.
"I did feel a little bit of pressure, not from others but from myself," she said.
"I called my dad a couple days ago and he said, `Just relax, you can't control everything, just play the game that you want to play and that you planned'."
