The Rays claimed minor league right-hander Rob Delaney off of waivers from the Twins, according to LaVelle E. Neal III of the Minneapolis Star-Tribune (on Twitter). The Twins had designated Delaney for assignment when they claimed Dusty Hughes from the Royals earlier in the week.
Delaney has appeared in just one big league game so far, but the 26-year-old right-hander has plenty of minor league experience. He has a 2.96 ERA with 9.5 K/9 and 1.9 BB/9 in 242 minor league relief appearances. Last year he posted a 3.44 ERA with 8.4 K/9 and 2.3 BB/9 in 83 2/3 innings for the Twins' top affiliates.
The Rays lost most of their best relievers this offseason, but they have added or re-signed Dirk Hayhurst, Kyle Farnsworth, Christopher Archer, Adam Russell, Cesar Ramos, Joel Peralta, Jonah Bayliss, J.P. Howell, Cory Wade and R.J. Swindle, as MLBTR's Transaction Tracker shows.
