Roman Anthony's sister has spoken out after going viral during his debut and gaining thousands of followers overnight.

The Boston Red Sox called up top prospect Roman Anthony two days after the 21-year-old outfielder hit a 497-foot grand slam for Triple-A Worcester.

Anthony received the biggest cheer of all during pregame introductions and then a standing ovation when he came to bat in the second inning.

For some, it might seem that Kristian Campbell, Marcelo Mayer and Roman Anthony have cleared the highest hurdle in their baseball journeys — making the leap between Worcester and the parent club in Boston.
