The Reds and Nationals will meet for the final time this season in Thursday's rubber game at Great American Ball Park.
Bronson Arroyo will pitch for Cincinnati against Washington right-hander Zach Day.
Arroyo is coming off his first and only loss with the Reds. Although credited with a quality start for giving up three earned runs over six innings, he allowed a career-high 11 hits in Saturday's 3-1 defeat at Arizona.
The last time Arroyo faced Washington was April 26 at RFK Stadium, when he gave up just one hit in eight innings for a smooth 5-0 victory.
CIN: RHP Bronson Arroyo (5-1, 2.36 ERA)
Arroyo has six quality starts in seven games for the Reds this season. The team is 5-2 in games Arroyo pitches and average 5.6 runs per game.
WAS: RHP Zach Day (2-3, 7.11 ERA)
Day, a Cincinnati native and 1996 graduate of LaSalle High School, will make his second career start in his hometown. He allowed two runs and six hits in a win for the Expos on June 4, 2004.
Player to watch
Adam Dunn is 3-for-8 (.375) with two home runs in previous meetings vs. Day.
