Spieth aging in style

The Masters and U.S. Open champion turned 22 on Monday, and celebrated by enjoying some quality time with his sister Ellie… while wearing a chicken hat, as one does.

Spieth's down to earth nature is one of the reasons that fans and sponsors are indulging in something of a love affair with the Texan, and his birthday snapshots aren't likely to change that.

Elle suffers from a neurological disorder, and Spieth has spoken of how she inspires him and keeps him grounded.

“Ellie certainly is the best thing that’s happened in our family,” Spieth said. “It helps put things in perspective that I’m lucky to play on tour and to compete with these guys, it’s been a dream come true. I definitely attribute a lot of that to her.”
