it depends on how you define a sport. golfers still need things like technique and so on to actually play well and it is mental. it does have a physical side to it so it is hard to argue against it being a sport. you can't say they don't physically go up against each other because the same thing occurs in swimming and athletics. it's something that doesn't seem like a sport but when you really think about it youo can't really say it isn't.
