Guardians ace pitcher Shane Bieber transferred to 60-day IL, expected to return mid-September

Bieber was transferred to the 60-day IL due to right elbow inflammation.
Despite rehabilitating well, he is not expected to return until mid-September.
Bieber had started all his scheduled games prior to the injury, posting a 5-6 record.
The move allowed the Guardians to add left-hander Daniel Norris to the roster.
Bieber's injury occurred in early July but did not require surgery.
