Paul Casey will use Nike’s new Vapor Fly driver this week at the Tour Championship, the golfer told GolfWRX.

Casey first tested the driver, which was added to the USGA’s List of Conforming Drivers this week, on Tuesday at East Lake, site of the Tour Championship. Casey said he did not expect to put the new driver in play this week, but changed his mind after his Tuesday’s practice round. Our photos show him practicing with the driver at East Lake on Wednesday, and he will be the first golfer to use the new club in competition.

Casey told GolfWRX that he likes the Vapor Fly because it launches higher than the Nike Vapor Speed driver he used throughout the 2015 season, and has a flatter trajectory at the apex of his ball flight that creates more carry distance and roll out.

Casey will play the Vapor Fly at the same 10.5-degree loft and neutral as his previous driver, with the same Mitsubishi Rayon Diamana White Board 73X shaft. He also has a new putter in the bag this week.

Casey’s chances this week

At No. 22 in the FedExCup Standings, Casey has a slim chance of winning the PGA Tour’s FedExCup. To claim the $10 million bonus, the golfer would need the following seven things to happen, according to PGATour.com:

Win the TOUR Championship No. 1 must finish in a 3-way tie for 13th or worse No. 2 must finish T5 or worse No. 3 must finish in a 3-way tie for third or worse No. 4 must finish T3 or worse No. 5 must finish in a 3-way tie for second or worse No. 6 must finish T2 or worse
