The 15th game of the season was the first one the Challengers couldn't win. The C's saw their 14-game winning streak halted, as their cross-town rival Zürich Barracudas posted a 13-8 victory on Saturday, August 30 at the Heerenschürli ballpark. The C's first erased a three-run deficit in the third inning, but the Barracudas broke a 4-4 tie in the bottom of the fourth frame, as they scored six runs with two outs on four consecutive hits. The C's fought till the end, but weren't able to turn things around again. Juan de la Rosa Bautista led the offense with a RBI-triple.
