West Michigan sent nine batters to the plate in the first inning and jumped out to a 5-1 lead.
The Dragons trailed 6-2 through five innings before battling back. In the sixth, Tyler Callihan and Austin Hendrick collected back-to-back doubles to start the inning, and Garrett Wolforth delivered a two-run single to make it 6-4.
In the seventh, Quincy McAfee (2-for-3) launched a home run to left field to pull the Dragons to within a run at 6-5. But Dayton did not put another man on base after McAfee’s home run. The final eight Dragons batters were retired in order.
The Dragons are off Monday. They return home to Day Air Ballpark on Tuesday to host Peoria.
