The New York Yankees have acquired Aroldis Chapman from the Cincinnati Reds in exchange for four minor league players.

The Reds get right-handers Caleb Cotham and Rookie Davis and infielders Eric Jagielo and Tony Renda from the Yankees.

"We felt this was an opportunity for us to add a big arm to our bullpen," said Brian Cashman, who already has Dellin Betances and Andrew Miller at the back end of his bullpen.

A baseball source told ESPN's Wallace Matthews that the Yankees made the trade knowing both Florida law enforcement officials and Major League Baseball are continuing to investigate the Oct. 30 incident in which Chapman allegedly choked his girlfriend and then fired eight shots from a handgun in the garage of his Davie, Fla., home.
