Pittsburgh Pirates closer Felipe Rivero has changed his name to Felipe Vazquez.

Vazquez legally changed his surname to match that of his sister, Prescilla.

The 26-year-old took over as Pittsburgh's closer last season and saved 21 games with a 1.67 ERA.

Vazquez lives with his sister in Florida during the offseason. She has advised him on a number of career decisions, including when he dropped Scott Boras as his agent this offseason. His sister was a primary negotiator for his new contract with the Pirates, which was signed in January and could keep him with Pittsburgh until 2023.
