Pitchers and catchers don’t report to spring training for another month, but don’t tell New York Mets shortstop Amed Rosario that. He, along with Yoenis Cespedes and a few other players, have been in Florida getting ready for the season, and the team has posted a video of him working out on Twitter.
Rosario, who will make up half of the Mets double play combination this season (most likely with Asdrubal Cabrera as the other half), is taking swings with a chain attached to his bat.
The chain is designed to provide resistance in the swing and, ultimately, build up his strength.
