The Red Sox have signed veteran reliever Casey Janssen to a minor league deal, Peter Abraham of the Boston Globe reports on Twitter. He is expected to pitch at the Triple-A level after a preliminary trip through the low minors.
Janssen spent spring training with the Padres, but San Diego released him in late March when it became apparent he wouldn’t crack the roster. He had yet to sign with another organization since.
The 34-year-old pitched at the major league level most recently with the Nationals in 2015. He was unable to make up for a decline in fastball velocity that has worsened over the years. Despite minimizing baserunners (38 hits and eight walks in 40 frames), he was touched for five long balls and suffered from sequencing misfortune. The result was a 4.95 ERA.
Before that, Janssen had compiled an impressive eight-year run with the Blue Jays. Over 493 frames, he worked to a 3.52 ERA with 6.7 K/9 against 2.2 BB/9. At his best, though, from 2011 through 2013, Janssen struck out about one batter per inning with around two walks per nine while carrying a 2.46 ERA.
