Joaquin signed a minor league deal with the Tigers on Friday, Baseball America's Matt Eddy reports.
He pitched in Mexico in 2016. Joaquin washed out of the Giants organization in 2011 and has not posted impressive strikeout rates relative to his level since a brief run at Triple-A in 2009. He should serve as organizational bullpen depth in 2017.
The Washington Nationals continued to trim their spring training roster after moving the following players to their minor-league camp on Thursday: Yunesky Maya (Triple-A Syracuse), Eury Perez (Double-A Harrisburg), Jeff Fulchino and Waldis Joaquin.
