SuperStroke congratulates Emiliano Grillo on playoff victory at The Charles Schwab Challenge

Two-time winner uses Zenergy Flatso 1.0 XL putter grip to outlast tight leaderboard

Wixom, MI – SuperStroke, the No. 1 Putter Grip in golf and the leader in innovative Tour-proven golf grip technology, congratulates 30-year-old Argentina native Emiliano Grillo on his second-career victory at The Charles Schwab Challenge. Grillo secured a two-year playing exemption on the Tour courtesy of his two-hole sudden-death playoff win. He closed with a gutsy final-round 68, overcoming a double bogey on the 72nd hole to earn a spot in the two-man playoff. He then drained a tournament-clinching birdie on the second playoff hole to capture his first victory since his triumph at the 2015 Open.

Grillo, who earned his spot in the 2024 Sentry Tournament of Champions, The Masters and Players Championship with this victory, used a SuperStroke Zenergy Flatso 1.0 XL putter grip to close out the win and collect the $1.566 million winner’s check.

What a performance!”

Grillo finished eight-under-par over four rounds on the difficult Colonial Country Club layout, holding off the likes of world No. 1 golfer and the player who led the tournament after each of the first three rounds, to reach the playoff.
