Division Champions Reflect on Their Performances - Winter Invitational Presented by Callaway
HOLLISTER, Calif. — The AmateurGolf.com Winter Invitational presented by Callaway once again brought elite amateur talent to San Juan Oaks Golf Club, where firm, fast greens and a championship-caliber layout set the stage for standout performances across all divisions. What separated this year’s event, however, was not just the scoring — but the stories behind those scores. From clutch hole-outs to composed Sunday finishes, each division champion delivered a unique path to the top, and the winners were eager to share how they got it done.
Championship Division: Theo Anderson’s short game steals the weekend
Entering the final round one shot off the lead, Theo Anderson leaned on elite wedge play and clutch scrambling to post a closing 69, finishing the tournament at 4-under (71–69) to secure the Championship Division title. Theo is currently a freshman playing for the University of San Francisco Men's golf team.
His round featured an eagle hole-out on the par-4 12th, numerous momentum-saving par conversions, and a birdie on 18 to seal the win.
For Anderson, the Winter Invitational fit perfectly into his offseason preparation for spring collegiate golf.
His closing-round steadiness reflected exactly the performance he hoped would surface this week.
Asked why he circled the Winter Invitational on his schedule, Anderson summed it up simply:
Mid-Amateur Division: Chris Marin stays hot and takes the title
Chris Marin lit up San Juan Oaks on Saturday, carding seven birdies, including a blistering 31 on the back nine, to grab the early lead in the Mid-Amateur Division. His fast start proved decisive as he rode that momentum through the final round to claim the championship.
Marin praised the demanding setup:
As for his weekend formula?
Marin also earned Low Scorer honors for the Men’s Mid-Amateur (25–49) category.
Women’s Division: Cathy Zhang pulls away for a two-round win
Cathy Zhang (San Ramon, CA) backed up her opening-round 72 with a steady 74 on Sunday to secure the Women’s Division title at +2 (146).
Her consistent ball striking separated her from the field as she closed out a comfortable margin of victory.
Senior Championship Division: Craig Miyamoto holds off a tight field
After opening with a superb 69, Craig Miyamoto (Sacramento, CA) protected his lead through Sunday’s more challenging winds and firmer greens, finishing at +1 (145) after a closing 76.
The leaderboard stayed tight throughout the afternoon, but Miyamoto’s first-round cushion — and mistake-free early play — ultimately sealed the championship.
Super Senior Division: Jim Williams finishes strong to claim the title
Jim Williams (Orinda, CA) captured the Super Senior championship at +5 (149), highlighted by a composed 72 in the final round — one of the steadiest Sunday scores across any division.
His disciplined approach and clean back nine made the difference.
