The house boasts a 12-car underground garage, indoor basketball court, pool, golf-simulator room, grill room and wine cellar.\nSpieth captured the U.S. Open title at Chambers Bay in 2015 at age 21. He was the youngest winner since Bobby Jones, also 21, won the championship in 1923.\nThe Spieth family name can be translated to “successful” or “speedy” in Middle High German (an ancient form of the German language).

The two often crash with each other on the road, and host fake Twitter feuds against the other.\nLike any teenager going off to school, the cold reality of not having your parents around to help with the small stuff hit Spieth hard when arriving at the University of Texas. "I definitely appreciate my mom a lot more, all the things she did that I'm having to do on my own," Spieth said during his freshman year.\nSpieth says baseball was his sport of choice initially, but at age 13 he decided he needed to focus solely on his golf if he were to really reach his potential. "That was the hardest day of my life," he said.\nSpieth could be seen fidgeting with his hair before having to take off his hat at the end of a round. He's clearly self-conscious about it.
