The IronPigs sat through a lengthy rain delay on Wednesday before falling to Louisville 6-3 at Coca-Cola Park.
The 'Pigs and Bats endured a 1 hour, 15 minute rain delay before finally starting just before 8:20pm.
Zach Miner (1-2, 5.40), a reliever by trade starting after Tyler Cloyd's call-up by the Phillies, allowed four runs in the first inning to take the loss.
Cody Asche and Darin Ruf each homered in a losing effort for the 'Pigs.
The IronPigs (14-18) will wrap up their series with the Bats with a 10:35am morning game at Coca-Cola Park on Thursday.
