The Reds changers their rotation because of Thursday's off day:
Friday, Edinson Volquez
Saturday, Matt Belisle
Sunday, Johnny Cueto
Monday, Aaron Harang
Tuesday, Bronson Arroyo
The net effect is Belisle gets an extra day of rest and Arroyo gets two extra days of rest. Everyone else stays on turn.
They've got another off day May 8, so they may adjust again.
