Nats make Janssen signing official

Washington, DC ( - The Washington Nationals agreed to terms with reliever Casey Janssen on a one-year contract, the team announced Monday.

The deal also includes a mutual option for 2016.

"We are happy to add Casey Janssen to our stable of relief arms," Nationals general manager Mike Rizzo said. "We're excited about what he will bring to our bullpen - on the mound, as one of the most effective and consistent relievers the last several years, as well as in the clubhouse. He is a veteran guy who has a plethora of experience in late, high-leverage innings, and we're thrilled to add him to our mix."

Janssen, 33, joins the Nationals after spending 10 years in the Toronto Blue Jays organization. He spent the last three seasons as the club's closer, converting 81 of 91 save opportunities.

The right-hander owns a career record of 29-24 with a 3.52 ERA in 389 games.

To make room for Janssen on the 40-man roster, the Nationals designated pitcher Eric Fornataro for assignment.
