Jon Rahm

Age: 23

2018 PGA Tour highlights: 17 starts, one win (CareerBuilder Challenge), five top-10s

Ryder Cup experience: First appearance

Buzz: Yet another Ryder Cup rookie, Rahm avoided the sophomore slump by winning early in his second season and got into contention with a pair of top-5 finishes at the Masters and PGA Championship. He didn’t seriously contend at any of the four playoff events, and finding the right partner who can help Rahm keep his emotions in check will be key.
