Lydia Ko’s career-low 60, sparked by a last-minute putter switch, gives her a one-shot lead over Hyo Joo Kim’s 61 in Phoenix, marking the first time since 2003 two players opened double digits under par and rewriting the LPGA’s record books in the process.
Lydia Ko didn’t just open the Ford Championship with a bang—she detonated the record books. The 28-year-old Kiwi posted a 12-under 60, the lowest round of her LPGA Tour career, on Thursday at Whirlwind Golf Club’s Cattail course. This historic score was matched only by defending champion Hyo Joo Kim‘s 61, creating a stunning morning wave that left the field in the dust as afternoon temperatures soared toward 100 degrees.
Ko’s round was a masterclass in relentless pressure. She opened with four consecutive birdies and never looked back, capping her round with two more birdies to seal the career-best number. The only moment of “what if?” came at the par-5 seventh, where a tentative 7-foot putt for birdie lipped out, denying her a chance at a mythical 59—a score only Annika Sorenstam has ever posted on the LPGA, 25 years ago in Phoenix. Ko remained philosophical: “That would have been nice to hole that one. But who knows? Maybe if I holed that one I might not have holed the other two.”
The catalyst for this greatness was a piece of equipment Ko rarely tinkers with: her putter. Just days before the tournament, she switched to a new Scotty Cameron 12 model. “It just rolled good. Went in the bag on Tuesday,” Ko said. “This has only been one round but it’s a good start. You know, really couldn’t have been any better.” That quiet change on Tuesday erupted into a scoring frenzy on Thursday, proving that sometimes the smallest adjustments yield the biggest results.
A Morning Wave for the Ages
Ko and Kim’s sub-61 rounds represent more than just personal milestones—they are a rarity in modern LPGA play. According to LPGA records cited by the Associated Press, this is the first time since the 2003 Kellogg-Keebler Classic that two players opened a tournament double digits under par. Ko’s 60 is only the ninth round of 60 or lower in tour history, with the most recent being Lucy Li‘s 60 at Pinnacle Country Club in 2024.
Kim matched the magic with her own 61, a round highlighted by a stunning birdie-eagle-birdie finish, including a hole-out from the fairway on the par-4 eighth. Meanwhile, top-ranked Nelly Korda, fresh off a win in Florida and a runner-up finish in California, carded a 63, one of her career bests, but found herself three shots behind the morning leaders.
This morning wave effectively decided the tournament’s early shape. With afternoon starters like world No. 1 Jeeno Thitikul struggling to 2 under at the turn in the blazing heat, catching Ko and Kim became an almost impossible task. The scorching conditions clearly favored the early tee times, turning Whirlwind into a shootout for the first group out.
Historical Context: Chasing Annika’s Ghost
Every sub-60 round in women’s golf is measured against Annika Sorenstam‘s legendary 59, shot 25 years ago at the same venue but on the different, older course at Gainey Ranch. Ko’s 60 places her in an elite club, but the narrative of “what if” will follow her until a 59 is actually carded. For now, her round stands as the closest any active player has come to matching Annika’s feat at a Phoenix-area event.
Ko’s career trajectory makes this round even more compelling. A two-time major champion before turning 21, she has long been seen as a prodigy who fulfilled her potential early. At 28, she is now in her athletic prime but has yet to win a 2026 event. This 60 signals that her game is peaking at the right time, potentially launching a summer surge toward a third major title.
Fan Implications: The Resurgence Question
For fans, Ko’s round sparks two immediate questions: Can she convert this into a victory, and is this a sign of a full-season resurgence? Her past major wins prove she can handle the Sunday pressure of a lead, but the Ford Championship is a stroke-play event where consistency across 72 holes is paramount. The putter change—a bold move for a veteran who typically stabilizes her equipment—suggests she was searching for a spark. Finding it this early in the week is a massive confidence boost.
The duel with Kim adds another layer. Kim, as the defending champion, knows this course and these conditions. Their head-to-head battle over the next three days will be the main story, with Korda and others in pursuit. The morning’s scoring explosion has set a target that may require another low round to catch.
The Heat Factor: A Silent Advantage
Purely from a strategic perspective, the late-morning heat was a silent participant. The course firming up and players fatiguing in the 100-degree afternoon heat made the morning wave’s scores look even more dominant. Ko and Kim benefited from cooler temperatures and softer greens, advantages that evaporated for later starters. This weather dynamic will influence tee-time strategies for the weekend, with leaders potentially wanting earlier slots to maintain scoring opportunities.
Ko herself acknowledged the patient approach required: “I feel like I stayed patient and was rolling it really well.” That patience, combined with the new putter’s feel and favorable conditions, created a perfect storm of factors that aligned for one of the best rounds in modern LPGA history.
Why This Matters for the Big Picture
Beyond the immediate tournament drama, Ko’s 60 underscores a broader trend in women’s golf: scoring is getting lower, equipment is evolving, and the mental fortitude to chase history is becoming more visible. Her willingness to change a key piece of equipment days before a tournament also highlights a modern golfer’s adaptability—no legacy is safe from tweaks in pursuit of perfection.
For the LPGA Tour, a star like Ko lighting up the leaderboard in Phoenix generates crucial momentum during a packed spring schedule. Her global appeal, rooted in her New Zealand heritage and early stardom, draws eyes to the tour at a key moment. If this round translates into a win, it could be the catalyst that defines her 2026 season.
The stage is now set. With a new putter in her bag and a career-low round in the books, Lydia Ko leads by one over Hyo Joo Kim, with the ghosts of Annika’s 59 and a sweltering Arizona heat adding layers to an already captivating story. The weekend at Whirlwind won’t just be about who posts the lowest score—it will be about who can harness the energy of a round that, for one morning, made the impossible seem routine.
