Lydia Ko's coach admits the world number one faces some challenges to rediscover her best form as the defence of her second Major looms at the end of the month.
Ko hasn't won on the LPGA Tour since last July with her best result this year, tied for 8th.
Ko returns to action this weekend at the Founders Cup in Arizona with the year's first major, the ANA Inspiration at the end of the month.
Coach Gary Gilchrist said Ko has uncharacteristically battled to consolidate key opportunities.
"She's struggling to keep gaining on the momentum in her round. You know one or two shots that cause her to not birdie a hole where she's put herself in a position to birdie a hole."
Gilchrist said it would be good to see her move away from her well known cool, calm demeanour.
"I think it's good to play towards your personality, but I think she is the world number one player and I think that a little bit more intensity on the course would really help her keep her energy level and her focus."
He also thinks Ko is still struggling with her new equipment.
The world number one switched from Callaway to PXG at the beginning of the year, and Gilchrist said Ko's yet to fully adjust to the gear.
"It's like a blind date, getting used to it. I think it's going to take a little bit of time, but I think once she comes back now to the US I think we'll spend some time."
Gilchrist said her body language is the main thing he's working on.
He said when he watches her play he feels her body language could be more intense and more aggressive.
