In this week’s “The Starter,” golf delivered one of its clearest reminders that careers do not move on a shared clock. Jackson Koivun won in his third professional start at 21, Jenny Shin ended a wait of more than 10 years for her second LPGA Tour title at 33, and Jerry Kelly claimed his third senior major at 59.

The PGA Tour: Koivun Turned A Breakthrough Into A Playoff Race

Scheffler’s 63 Made Sunday More Than A Coronation

Koivun began Sunday at the 3M Open with a three-stroke lead after a third-round 61 that included a tournament-record 28 on the back nine. He finished with a bogey-free 66 at TPC Twin Cities, reached a tournament-record 25-under 259 and defeated Scottie Scheffler by three.

The margin looked controlled, but the pressure was real. Scheffler played five groups ahead and shot 63, reaching 22 under and placing the world’s top-ranked player directly beneath Koivun’s name on the leaderboard. Koivun’s advantage, which had grown to five, was down to three when he faced a par putt at the ninth.

He made it and later called it the biggest putt of his week because missing would have reduced the lead to two. Koivun completed his second consecutive bogey-free round, one month after turning professional and shortly after helping Auburn win the NCAA championship.

The College Pipeline Has Changed The Meaning Of Rookie

Koivun had already made 10 PGA Tour starts as an amateur. This was his third professional start, not his third exposure to Tour golf.

That distinction matters because college players now arrive after competing in deeper schedules, working with larger support teams and gaining access through programs such as PGA Tour University Accelerated. Scheffler said Sunday that players are reaching the Tour from college more prepared than his generation was.

Koivun became the fourth rookie winner this season. The victory gave him a two-year exemption and $1.584 million, then moved him 124 places to No. 70 in the FedEx Cup standings. With two regular-season events remaining, his first title also placed him directly on the playoff line.

The LPGA Tour: Shin Added A Rare Gap Between Victories

Wire-To-Wire Did Not Mean Stress-Free

Jenny Shin opened with rounds of 66 and 67 at Dundonald Links, followed with a 71 and carried a five-stroke lead into the final round of the Women’s Scottish Open. She closed with a 75, finished at 9-under 279 and defeated A Lim Kim by two.

The final round tightened after Shin made three consecutive bogeys from Nos. 6 through 8. Her approach at the ninth rolled off the green, but a 7-foot par putt stopped the slide. Birdies at Nos. 10 and 12 rebuilt enough separation for her to absorb two late bogeys.

Kim shot 68 to place second at 7 under, while Pajaree Anannarukarn finished third at 5 under. Shin did not produce the sharpest golf of her week Sunday, but she protected the work that had separated her from the field through 54 holes.

Her Win Deepened An Unusually Open LPGA Season

Shin’s first LPGA Tour victory came in 2016. Her second arrived 10 years, two months and 25 days later, making her only the third LPGA player since 1980 to go at least a decade between official victories.

That long interval made Shin’s result historically rare, while the broader season around it remains notably crowded. Shin became the 12th different winner through 19 LPGA events in 2026 and only the second wire-to-wire champion of the season.

Those numbers describe a year with plenty of winning depth but little weekly certainty, one that now moves directly into its final major. The AIG Women’s Open begins Thursday at Royal Lytham & St. Annes. Shin will arrive as the most recent winner, while the rest of the field carries another reminder that the LPGA’s competitive order can change quickly.

The Senior Open: Kelly’s Consistency Carried A Major Reward

Four Rounds In The 60s Beat The Sunday Charges

Jerry Kelly began the final round of the Senior Open tied with Cameron Percy and finished it holding the Senior Claret Jug. His closing 68 completed rounds of 66-68-68-68 and a 10-under total of 270, two strokes better than Percy, Matt Gogel and Darren Fichardt.

Gogel applied the strongest early pressure with a bogey-free 63, moving from 1 under to 8 under and establishing the clubhouse target. Fichardt closed with a 66 to join him, while Percy shot 70 after sharing the 54-hole lead.

Kelly never posted a round higher than 68. He birdied the 72nd hole to complete his 14th PGA Tour Champions victory, his third senior major and his first Senior Open title in nine appearances.

Senior Golf Opened A Door Back To St Andrews

At 59, Kelly became the oldest Senior Open winner since Bernhard Langer in 2019. He also became the first American-born champion since Marco Dawson in 2015.

The victory carried a reward beyond the trophy. Kelly earned a place in the 2027 Open Championship at St Andrews, returning him to the championship where he had never achieved what he wanted during his regular-tour career.

That is one of the strongest functions of senior golf. It does not change the first half of a player’s record, but it can add new major victories, new exemptions and new historical connections. Kelly’s week at Gleneagles did all three.

The calendar will not leave much time for any of the winners to stand still. Koivun planned to travel directly to the Rocket Classic before the Wyndham Championship, with his playoff place unsecured. Shin faced a drive to Manchester and preparation for the AIG Women’s Open. Kelly now has a future date at the Home of Golf.

What We’ll Remember From This Week

What I think I will remember most is not the 38 years separating the youngest and oldest champions. It is that each victory answered a different career question. Koivun showed how quickly a prepared college star can convert opportunity, Shin proved a decade between titles does not automatically close the winning window and Kelly added the major and Open connection that had remained outside his regular-tour record.

Golf used the same four-round test in Minnesota and on two very different Scottish courses. It simply delivered the rewards at three very different points in three careers.
