A top prospect of the Arizona Diamondbacks' videotaped his parents becoming overwhelmed with emotion after they received his Christmas gift.

Pavin Smith, chosen seventh overall in the 2017 Major League Baseball draft, used part of his more than $5 million signing bonus to pay off his parents' mortgage.

He surprised them with the news via a letter that his mother read aloud and the video went viral on Twitter.

"Just 'home' and 'love' - the words are small, four letters unto each. And, yet you will not find... words more sweet than 'home' and 'love'," Smith's mother read.

"Thank you for raising me in a great home filled with love," Smith wrote. "Because of all the sacrifices you made to get me where I am, I want our family home to be yours."

"Thank you for everything you have done for me," Smith said.

On "Fox & Friends," 21-year-old Smith and his parents talked about the emotional video with Brian Kilmeade. 

"It was a very emotional moment. Just seeing it again gets me kind of choked up," Pamela Smith said. 

Pavin said it was "the least he could do" for his parents after all of the money and time they spent helping him achieve his dream.
