Callaway Golf today officially announced that Si Woo Kim and Hudson Swafford have both joined their Tour Professional Staff. Both players will make their first start as Callaway staffers this week at the Sentry Tournament of Champions. “I’m joining Callaway because of the performance of their equipment,” Kim said. “I’ve had the opportunity to test a number of different brands, and without question Callaway was the best for me. Working with their driver technology is something I’m especially excited about, and I’m ready to get started this week.” The 22-year-old Kim became the youngest ever winner of the PLAYERS Championship last year, and competed for the 2017 International Presidents Cup team. Swafford is coming off the best season of his career, highlighted by his victory at the 2017 CareerBuilder Challenge. “I truly believe that Callaway makes the best golf equipment,” Swafford said. “I’ve been so impressed by their products and working with the dedicated Tour Team, and I’m very confident in the clubs that are in my bag.” Swafford and Kim join an impressive list of new Callaway Staff Pros who have been announced this week, a list that includes 2017 Masters Champion Sergio Garcia, and 2017 PGA Tour Rookie of the Year Xander Schauffele.
