The Cincinnati Reds decided to go with Cody Reed as the number five starter to start the season. Reed had a tough spring. He also has shown that he can relieve, but not start on the MLB level.
Amir Garrett, though, has shown bursts of being ready to start at the MLB level. He also has been a starter his entire time in the minors. Garrett is a starting pitcher.
This year Garrett has pitched three games in relief. On Opening Day Garrett pitched one inning, walking one. He struck out two and did not allow a hit.
