The Green Bay Bullfrogs erupted for 17 runs on 18 hits in routing the Eau Claire Express 17-2 at Joannes Stadium Thursday night.  Brian Celsi led the offensive attack, going three for five with four runs batted in and three runs scored.   David Armendariz and Ransom LaLonde each had three hits while Justin Seager drove in three.  After scoring twice in the first, the Bullfrogs built a cushion with three more in the third.   Green Bay broke it open with an 8 run 7th inning and added four more in the 8th.  It wasn't all offense however as starting pitcher Bradley Wallace, a sophomore from Arkansas State, improved to 3-0 by working seven innings, allowing a run on five hits with nine stirkeouts.  Bradley actually watched his ERA go up, entering the game with a glittering 0.47 earned run average.  The win was the fifth in a row for Bullfrogs, who host the Express again on Friday night at Joannes Stadium at 7:05 PM.
