Mat Nelson went 3-for-4 and Jay Allen went 2-for-3 with two RBI and scored two runs. Michel Triana had a solo home run.
Right-hander Miguel Medrano (2-4) picked up the win in relief. Donovan Benoit retired the only batter he faced in the seventh for his 12th save.
In the nightcap, Dayton’s Noelvi Marte went 3-for-4 with two RBI and Austin Hendrick had a two-run double. Dayton scored five runs in the second. The Dragons added two more in the sixth on a two-run home run by Triana.
Dayton’s Chase Petty, acquired by the Reds by the Twins for Sonny Gray, picked up his first professional win. The 19-year-old right hander allowed two hits in five innings of work. He struck out two and did not walk a batter.
