The Diamondbacks are considering going to a six-man rotation in September in order to limit the workload of pitcher Patrick Corbin, according to azcentral.com.
Corbin tossed 186 1/3 innings last year, and has already thrown 177 2/3 in 2013. If the team were to move to a six-man rotation, Corbin would lose one or two starts. It's unclear what pitcher would serve as the sixth starter, but the most likely candidates are David Holmberg and Tyler Skaggs.
