No. It’s a much tougher test

Stick that driver back in the bag and hold up a minute.

Lydia Ko will one day contend for another major, perhaps even later this year, but she’s not ready to push for win number three at the US Open at Shoal Creek in Alabama later this month.

It’s understandable some people might point to her glorious three-wood at Lake Merced on Monday, which set up her first win on the LPGA Tour in almost two years.

However, majors are a different beast.

Just look at Tiger Woods. A couple of top-five finishes and some couldn’t resist tipping Woods’ comeback to go from good to glorious by contending, or even winning, the Masters at Augusta last month. He finished in a share of 32nd.

Take nothing away from Ko. She was sensational in winning the Mediheal Championship in San Francisco, albeit on a course where she’d twice one.

She’s also a member at the Californian course. What better place to get hot on?

In eight previous tournaments this year, the 21-year-old missed the cut once, nabbed one top-10 finish, and was otherwise anywhere from 19th to 33rd.

Not surprisingly, progress wasn’t immediately obvious under new swing coach Ted Oh, who has been working with the Kiwi only since she replaced Gary Gilchrist with him in February.

Changing a player’s stroke is no easy feat. Simplifying her swing in a bid to find a quicker rhythm with increased power is what her third coach since going pro in 2013 has done.

Forget that magic three-wood for a moment, Ko’s ball-striking still needs work and expectations must be tempered as the second of five 2018 majors looms.

Of course, that could change if Ko tears it up at the Texas Classic, starting today. Who knows, perhaps burying the burden of such a lengthy drought will result in more Ko magic.

She certainly appeared relaxed during a tense final round at Lake Merced, even skipping and dancing off the green at one stage.

It must be remembered the LPGA Tour has changed significantly since Ko was at her best, stacking up wins on her way to becoming the most successful teenager in the sport’s history. It’s now a heck of a lot tougher to win than ever before.
