Bubic (elbow/shoulder) threw a two-inning up-and-down bullpen session Sunday, MLB.com reports.
While working his way back from left elbow soreness, Bubic suffered a setback in his first rehab start June 9 at Triple-A Omaha, when he reported shoulder discomfort following the outing. The southpaw underwent an MRI that revealed no structural damage to either his elbow or shoulder, an encouraging development that has allowed him to resume building back up. Having now completed a bullpen session, the 28-year-old could restart his rehab assignment soon, provided he doesn't experience any renewed discomfort. Before being shelved May 18, Bubic posted a 3-2 record with a 4.11 ERA, 1.23 WHIP and 51:26 K:BB across 50.1 innings (nine starts).
