Reds relievers lead the National League in bullpen ERA at 2.76, and rank second in opponents' batting average at .217, behind the Dodgers' .213 mark, entering Saturday.
Cincinnati has seen 30-plus appearances from Sean Marshall, Jose Arredondo, Logan Ondrusek and Aroldis Chapman this season. The four have combined for 13 wins.
Deeper into the 'pen sits a robust righty, Alfredo Simon.
In his 20 appearances this year, Simon has quietly held the lowest ERA on the club at 1.67.
He earned his first win of the season on Friday night after tossing two scoreless innings against the Cardinals, and Reds manager Dusty Baker said there may be more in store for the 31-year-old reliever.
"I told him, I said, 'Your role has a chance to elevate depending on your performance and how you do,'" Baker said. "That was huge to stop [the Cardinals] right as it was, and it gave us a chance to come back and win."
Simon spent four seasons in Baltimore, making 78 appearances, before being acquired by Cincinnati this year.
