Rather, the Brewers will follow in the footsteps of the Oakland Athletics by running a bullpen game in the series opener, per manager Craig Counsell:

At minimum, toggling through relievers does give the Brewers the flexibility to pinch-hit whenever the pitcher's spot is due up. That could prove handy, depending on the situation. It's unclear who the Brewers will deem their "opener," or how they'll sequence their relievers.
Meanwhile, Counsell announced that Jhoulys Chacin will start Game 2 on short rest. Chacin pitched Monday's tiebreaker game. In other words, Milwaukee's bullpen could be very busy the next two days -- all by design.
