After the 4-2 win, where Broxton retired the side in order to end the game, manager Bryan Price revealed that Chapman was not available.
"He was out in the outfield and had a little bit of a tweak of the hamstring and we wanted to stay away from him today. And we hope he'll be ready to go [Monday]," Price said.
Broxton collected his sixth save of the season and his first since April 29 vs. the Cubs. Chapman is 17 for 19 in save chances and has a 2.55 ERA in 24 appearances. He earned a save in Friday's game, also a 4-2 victory for Cincinnati over Milwaukee.
