University of Florida baseball star and latest Kansas City Royals teammate Brady Singer might soon be known as much for the size of his heart as he is for the power of his arm.The 22-year-old right-hander posted a video to Twitter on Tuesday showing his parents receiving their Christmas present from him. The recently signed MLB prospect used some of his $4.25 million signing bonus to pay off his parents' debt.The video shows his mother, Jacquelyn Singer, struggling more and more to fight back tears as she reads a card from her son thanking his parents for the sacrifices they made to help him follow his dreams.Today is very special to my heart. To give back to the two people who have given up everything to support my brother and I. I can’t thank them enough. Love you Mom and Dad pic.twitter.com/AFHi2Xma0c— Brady Singer (@Bsinger51) December 25, 2018"There's absolutely no way I could have done all this by myself. Both of you constantly took off of work and spent every dime you made just to put a smile on my face," Singer wrote to his parents. "The money you both spent on traveling and gear, hotels, food and all those Gatorades I drank is much more than I can ever give you… I am paying off the loan from the bank. Also, I paid off all your debt as well."His mother grabbed his father, Brett's, hand and gasped, then continued reading the letter."Now instead of trying to save money every weekend to try to replace the savings account you drained on traveling to see me play baseball, you can spend it on yourselves because you deserve the very best."The video has already been viewed millions of times and garnered national attention.Singer, a Eustis High School graduate and Lake County native, joined the UF baseball team as a freshman in 2016. By his junior year, 2018, he was a star player being courted by MLB teams. He was drafted by the Toronto Blue Jays in 2015, but didn't sign. He was a starting pitcher during UF's 2017 NCAA championship run.During the 2018 season he helped UF make it to the College World Series and won the Dick Howser Trophy, awarded to the national college baseball player of the year, among several other honors. According to the UF website, in 2018, Singer "enjoyed perhaps the most decorated season of any Florida player in school history."He signed with the Kansas City Royals in July 2018.
