Rizzo had missed the last 18 games due to a back problem but drove a pitch from Pedro Villarreal (0-1) over the wall in center field. Rizzo's homer was his 31st of the season and gave Hector Rondon (4-4) the win after he tossed a scoreless inning of relief.
Travis Wood didn't get any run support and couldn't earn his ninth win of the season despite producing one of his best outings of the year. Wood threw six scoreless innings, allowed only three hits, and lowered his ERA to 4.86.
Cincinnati starter Alfredo Simon gave up five hits in seven innings.
