A friend of Tiger Woods opened up on how the golfer might be dealing with a lot in his private life amid break-up from Lindsey Vonn.

Tiger Woods Has 'A Mountain To Climb' After Scoring His Worst Round?

On Tuesday, New York Daily News posted an interview with Jason Day who said that Woods's personal life should be kept to himself although he had more to say about the golfer's skills in getting back to being the winner people know him to be.

"Who knows what's going on with Tiger right now," Day said. "We're friends, but I don't want to get into his personal life and I don't want to. That's his stuff and he deserves his privacy. But when it comes to golf, it's very difficult because you could have all the tools in the world, but if you really don't want to be there or if there's something that's off course that's playing on your mind."

Is Lindsey Vonn Doing Alright After Break-Up With Tiger Woods?

"The game of golf is so mental, and if you don't have everything in the right order, it's very difficult to win golf tournaments," Day added.

Woods has been having a difficult time in the sport lately when he scored an 85 in the third round at the Memorial Tournament, which is not good at all. Based on what Day said, it's possible that the athlete may still be recovering from his break-up, but only time will tell if he can get back to where he was.
