It was Cubs legend Ernie Banks who famously said, "let's play two," but after the Reds swept a doubleheader from Banks' former team on Tuesday, Reds legend-in-the-making Billy Hamilton did him one better -- "Let's play three."

Hamilton hit a broken-bat single into left in the ninth inning to give the Reds their first doubleheader sweep since 2009 with a 6-5 victory over Chicago after taking the first game 4-2. The win completed the team's biggest comeback of the season, erasing a 5-0 deficit thanks to runs in each of the last five innings and 6 1/3 scoreless innings from the bullpen. It also moved the Reds team that entered the day five games behind the first-place Brewers to just three-and-a-half games back of Milwaukee, and a half-game behind second-place St. Louis.

"That's one thing I strive for, to get in a situation like that, I want to be the guy to be in the situation like that," Hamilton said. "Even though I have teammates, I want to be the guy in a situation like that."

The Reds scored in each of their final five innings to overcome the five-run hole dug by starter David Holmberg, making his Reds debut.

Hamilton's RBI was his second of the comeback. His RBI triple in the seventh inning brought the Reds to within a run, 5-4, before Jay Bruce's RBI double in the eighth tied the game.

Brayan Pena led off the ninth inning with a pinch-hit single on a pop-up that found space between Cubs third baseman Luis Valbuena, shortstop Starlin Castro and left fielder Chris Coghlan. He was then replaced by pinch-runner Mike Leake, who went to third on Mesoraco's single to left to bring up Hamilton.
