Three White Sox hurlers are out for the season, per reports from Scott Merkin of and James Fegan of The Athletic. Right-handers Ryan Burr and Jimmy Lambert have undergone Tommy John procedures, while fellow righty Zack Burdi has a ligament tear in his patella.

Burr’s the lone member of the trio who has pitched in the majors to this point. The 25-year-old debuted with the White Sox last season and has since registered a 5.52 ERA/5.60 FIP with 7.98 K/9, 4.3 BB/9 and a 43.7 percent groundball rate in 29 1/3 innings. Chicago placed him on the injured list May 28 with a right elbow capsule strain.
