The Pirates will announce the signing of left-handed reliever Joe Beimel on Friday, tweets Troy Renck of the Denver Post.
Beimel, who went to Duquesne University in Pittsburgh and has ties to the area, as Renck notes, was originally drafted by the Bucs in 1998 and made his big-league debut with them in 2001.
After breaking into the Majors in a swing role, Beimel has evolved into a well-traveled lefty specialist (limiting LHB to .259/.320/.400 in 929 career PA), having spent time with the Dodgers, Nationals and Rockies over the past three seasons.
Beimal, who will turn 34 in April, has a 4.16 career ERA over 562 1/3 innings.
