The Red Sox have released veteran reliever Casey Janssen, as per the International League’s official transactions page. Today was the day that Janssen could opt out of his minor league deal with the Sox, Brendan McGair of the Pawtucket Times reported (Twitter links), and the righty elected to look for an opportunity with another team.
Janssen has signed minor league contracts with Boston and San Diego in 2016 but has yet to appear in the majors this season. He posted solid numbers at the Triple-A and low-A levels for the Sox, delivering a 2.87 ERA, 6.9 K/9 and 3.00 K/BB rate over a combined 15 2/3 innings at both levels.
Best known as a longtime fixture in the Blue Jays bullpen, Janssen served as Toronto’s closer from 2012-14 before losing the job after struggling in the latter half of the 2014 season (due in part to an illness picked up during an All-Star break vacation). He posted a 4.95 ERA over 40 IP out of the Nationals bullpen in 2015 as his fastball velocity and ground ball rate declined for the second straight season.
