Aside from a disastrous one-start cameo with Arizona earlier this month, Medlen had spent the entire season at the Diamondbacks' Triple-A affiliate in Reno, where he held a a 5.03 ERA over 34 innings this season. He'll end his 13-year professional career with a 3.33 cumulative ERA over nearly 600 big-league innings between the Braves, Royals and Diamondbacks.

Medlen was up for just one start and got shelled, giving up seven runs on nine hits and four walks in just four innings Friday against Houston. Braden Shipley was promoted to take his place on the roster.

The 32-year-old was called up from the minors before this start with Robbie Ray (oblique) going to the disabled list and he was roughed up in a tough assignment against a talented Astros lineup. Even if he's given the benefit of the doubt based on the matchup, he wasn't pitching particularly well in Triple-A with a 6.00 ERA over his four starts, so there's little reason to expect he'll establish himself as a streaming option regardless of the competition.

As expected, Medlen will join the big-league squad to start Friday's game against the Astros. The 32-year-old last appeared in the majors in 2016 for the Royals, where he produced a 7.77 ERA in six starts for Kansas City. He'll face off with Gerrit Cole in his season debut. To make room for him on the active roster, Silvino Bracho was optioned to Triple-A and Taijuan Walker (elbow) was transferred to tehe 60-day disabled list.
