Kansas City Royals pitching prospect Brady Singer pays off parents' debt for Christmas

When the Kansas City Royals drafted pitching prospect Brady Singer this summer, the 18th pick knew how he wanted to spend part of his $4 million signing bonus.

He waited until Christmas to surprise his parents with a special gift.

Video shows his tearful mother reading a letter from Brady explaining that he was paying off all of their debt as a thank you for all the support they showed to him growing up and playing baseball.
