Dunn went 2-for-3 with a solo home run, a walk, two stolen bases and three total runs scored in Thursday's 15-3 loss to Atlanta.
It was a rough day for the Reds overall, though Dunn provided a bright spot -- the 26-year-old outfielder swiped his first two bases in the majors before swatting his first big-league homer, a 422-foot blast off Chris Sale. Dunn had gone just 2-for-21 in 16 games prior to Thursday. He'll likely fill a bench role for Cincinnati over the final week of the season.
