Taillon underwent surgery Wednesday to repair an inguinal hernia, Bill Brink of the Pittsburgh Post-Gazette reports. It sounds like everything went as expected, as the Pirates are sticking to the initial two-month estimated recovery timetable for Taillon. The second overall pick in the 2010 first-year player draft, he appeared close to returning to a full-season affiliate following 2014 Tommy John surgery before the groin injury popped up.
