Leake's turn comes up on Friday in Philadelphia. Volquez is pitching tonight. Could Volquez take that turn to keep Leake's innings down?
More radical thought. Could Leake go to AAA to rest for the next ten days, which include the All Star break, and then come back a few days after the break? This would also keep Leake's innings down, with Volquez getting his starts.
If something like this happens, the beneficiary is Wood, who would stay with the big club. Wood's turn is Tuesday against the Mets and he obviously will take that turn.
The other option is to keep Leake in his normal rotation and replace Wood with Volquez next Sunday in Philadelphia. That would be Wood's turn after NY.
Or, the Reds could keep Volquez in the minors until afte the ASB and keep both Leake and Wood in the rotation.
