Hutchison was optioned to Triple-A Indianapolis on Wednesday, Bill Brink of the Pittsburgh Post-Gazette reports.
The race for the No. 5 starter role in Pittsburgh is down to Tyler Glasnow and Trevor Williams with Hutchison out of the picture for the time being. Hutchison gave up just six hits in his first three spring appearances (nine innings), but he was then rocked for 21 runs on 27 hits in his subsequent three starts. The 26-year-old right-hander owns a 4.93 ERA, 1.37 WHIP, 8.3 K/9 and 2.8 BB/9 over 417.2 career innings at the major-league level.
