Via the team's transactions page, the Pirates have claimed righty Jorge Rondon from the Orioles, thus completing a sort of de facto trade -- the Orioles designated Rondon for assignment when they claimed Vance Worley from the Bucs.
This is one of those Pirates pitching pickups that's based more on scouting than on performance. The 27-year-old Rondon struggled with walks while coming through the Cardinals system, and while he began limiting free passes in the minors starting in 2014, he's continued to have control issues in very short stints in the big leagues with the Cardinals, Rockies and Orioles in the past two years.
