The Rays acquired Roycroft from the Cardinals on Tuesday in exchange for a player to be named later or cash considerations.
Roycroft has posted a 6.41 ERA, 1.77 WHIP and 52:37 K:BB over 60.1 innings at the major-league level and had been designated for assignment last week. The 6-foot-8 righty's sinker rates well in terms of Stuff+, and it would not be a surprise if the Rays are able to coax more out of him. Roycroft will report to Triple-A Durham for now.
