Right-handed starter Luis Severino was promoted from High-A Tampa to the Thunder Tuesday afternoon.

The 20-year old Dominican native has seen his stock rise as quickly as any in the Yankees organization this year. After starting the season with Low-A Charleston, he was promoted to Tampa in late June, posting a 1.31 ERA in four starts at that level.

Severino also impressed as one of the two Yankees representatives at the MLB Futures Game in Minneapolis. He didn’t allow a run in his one inning of work, striking out top Texas Rangers prospect Joey Gallo.

The news was first reported by Baseball America’s Josh Norris.
