Boxberger (back) emerged from an impressive one-inning outing for High-A Charlotte on Monday declaring that his arm felt "great," Roger Mooney of the Tampa Bay Times reports.
The veteran reliever struck out the side on 14 pitches, 11 of which he threw for strikes. It was Boxberger's long-awaited first rehab outing, and he'll report to the trainers Tuesday for confirmation on his next step. The plan remains for Boxberger to see action in multiple games in the minors before his 2017 big-league debut.
