J.T. Poston survived a marathon Sunday at Muirfield Village, playing 32 holes, including a two-hole playoff, to collect his fourth and biggest PGA Tour win at the Memorial Tournament. Notably, the win saves him from having to play 36 on Monday as it qualifies him for the U.S. Open in two weeks.
Poston has overhauled his golf bag over the past few months, adding several new clubs and a new golf ball to his setup.
The 33-year-old is the first winner on the PGA Tour with a Titleist GTS driver, using a 9-degree GTS3 with a Mitsubishi Diamana BF shaft. (Mitsubishi’s 10th win of the year!)
He also got the first victory with the new 2026 TaylorMade Spider Torched line after switching to a Spider Tour X, L-Neck at the Charles Schwab Challenge last week. The putter swap paid off big time as Poston, who had played multiple putters this season already, gained nearly seven shots on the greens, ranking third in the field this week.
But he also switched golf balls, to the 2026 Pro V1x Left Dash, in Fort Worth, and it may have helped him shoot that absurd Friday 65 in windy conditions, which shot him into the lead.
“It’s supposed to help me a little bit in the wind,” Poston said Friday of the lowering spinning Pro V1x variant. “So we felt like today was going to be a good test of that and it obviously performed really well. We had a couple shots that I felt like didn’t quite hit ’em perfect and it hung in there pretty well.”
Poston first approached Titleist’s Tour team about the switch at the PGA Championship, specifically looking for better performance in the wind. He told the reps his Pro V1x was overspinning on his irons and wedges after he added speed recently.
After testing both Left Dash and the 2025 Pro V1 at home, Poston and Titleist’s J.J. Van Wezenbeeck decided to add Left Dash in Fort Worth, where he finished T35.
Heading into Charles Schwab, Poston was 85th in SG: Approach (+0.024). He picked up 1.4 strokes at Colonial before gaining more than +8 SG: Approach this week and ranking T4 in GIR.
Poston joins Jordan Spieth as recent converts to the new Left Dash.
