In the top of the fifth, Andrew Knapp became the first Lehigh Valley baserunner of the night when he reached on an error charged to Bats 2B Hernan Iribarren. Later in the frame, Knapp advanced to third on David Lough's double and both runners scored on Darnell Sweeney's go-ahead two-out, two-run single to give the Pigs a 2-1 lead.

Louisville had runners at first and second with one out in the home half of the inning, but RHP Frank Herrmann came on in relief of Pigs starter Phil Klein and got Jermaine Curtis to ground into a 6-4-3 double play and end the threat.

In the afore-mentioned four-run eighth, Knapp delivered a two-run single in the inning while Williams and J.P. Crawford each came through with RBI singles of their own to give the Pigs a 7-2 advantage.

In the top of the ninth, Sweeney (3-4, 2 2B, 2 RBI, 2 R) reached with a one-out double, advanced to third on a groundout and scored on Taylor Featherston's RBI single to give the IronPigs an 8-2 lead.
