Boxberger (abdomen) allowed two hits and a walk while retiring just two batters on 22 pitches in Thursday's appearance at extended spring training, Marc Topkin of the Tampa Bay Times reports.
Although the results were unimpressive, Boxberger took a big step forward by pitching in a game for the first time since undergoing core muscle repair surgery in mid-March. He did strike out two batters, and he's still expected to replace Alex Colome as the closer once he rejoins the Rays. Boxberger should be available in late May or early June.
