In a now-viral video viewed 4.6 million times, both Felix and Carrier become emotional during the exchange.
This was in part due to the close relationship they share, Felix's mom, Melissa Carrier-Damon of Sioux Falls told Fox News Digital.
"My dad has spent a lot of time with all our kids and that includes playing catch, helping with batting and coming to their games," said Carrier-Damon, who is Carrier's daughter.
Carrier-Damon described her father as a "lifelong" Los Angeles Dodgers fan.
He is also a retired school superintendent, she said.
