Buffalo (43-45) got some separation in the top of the second inning. Brad Emaus reached on a one-out single and moved to second when Raul Reyes walked. Lucas May knocked Emaus home with a double that bounced over the third-base bag and down the left-field line.

A couple batters later, Josh Rodriguez put the Bisons up 3-0 with a line-drive single that scored May. Next up, Adam Loewen appeared to break the game wide open with a three-run home run that rattled off the back wall of the Family Park in right field to give Buffalo a 6-0 lead.

Corey Brown and Jarrett Hoffpauir followed with consecutive sacrifice flies to score Maldonado and Valdez and bring the Chiefs to within five.
Valdez brought Syracuse (44-43) even closer in the bottom of the fourth inning. After Brett Carroll, Carlos Rivero, and Maldonado reached to load the bases, Valdez blasted a 2-0 pitch from Dylan Owen over the left-field wall for a grand slam to make the score 7-6 Buffalo.
