The Athletic | Lindsey Adler: Pitchers typically lose velocity as they age, especially flamethrowers who throw mostly fastballs. Unfortunately, that means Aroldis Chapman won’t be able to throw 100+ mph heaters forever. With an awareness that his fastball velocity is gradually losing speed as he gets older, Chapman has been working on a new pitch to add to his standard repertoire: a splitter. He began tinkering with the pitch during the long delay leading up to the 2020 MLB season and briefly used it on the field. After continuing to refine it this offseason, it will be fun to take note when he breaks out the pitch in 2021.
