The Brewers series rotation has been set and announced by the Reds (per a tweet by FS Ohio on Twitter).
THU: Homer Bailey vs. Braden Looper
FRI: Bronson Arroyo vs. Jeff Suppan
SAT: Aaron Harang vs. Manny Parra
SUN: Johnny Cuteo vs. Yovani Gallardo.
Seems like the best possible match-ups for the Reds as you could hope for (other than having to face Gallardo).
