Burdi is seen as a closer-type, but manager Rick Renteria said the 22-year-old needs to improve his fastball command, Paul Skrbina of the Chicago Tribune reports.
Burdi, a non-roster invitee to major league camp, has allowed three runs on four hits and four walks while striking out 10 in 7.1 innings over seven spring appearances. The 26th overall pick in the 2016 draft reached Triple-A Charlotte last season and is on the precipice of the majors in 2017. It will get really interesting if the White Sox eventually trade closer David Robertson. With Chicago in full rebuild mode, Burdi could ascend to the ninth inning role ahead of schedule.
