The Nationals signed right-hander Waldis Joaquin to a minor league deal that includes an invitation to Spring Training, MLBTR has learned. The hard-throwing 24-year-old became a free agent in November after the Giants designated him for assignment.
Joaquin made 19 relief appearances for the Giants from 2009-11, including five this past season. He spent most of 2011 at Triple-A Fresno, where he posted a 3.44 ERA with 4.9 K/9 and 4.2 BB/9 in 49 2/3 innings. After the season Joaquin pitched in the Dominican Republic to get some work in.
