CINCINNATI - Center fielder Billy Hamilton collected three hits, including his first career home run, and right-hander Alfredo Simon pitched six strong innings, lifting the Cincinnati Reds to a 3-2 victory over the Chicago Cubs on Tuesday at Great American Ball Park.
The game was delayed by rain on three separate occasions for a total of one hour and 45 minutes.
Hamilton went 3-for-4 with a homer, walk, stolen base and scored twice for Cincinnati (12-14).
Shortstop Starlin Castro went 1-for-3 with two RBIs for Chicago (8-17), and center fielder Emilio Bonifacio and right fielder Ryan Kalish added two hits apiece.
Simon (4-1) was making his first appearance since being hit with a $15 million lawsuit from a woman claiming he sexually assaulted her in a Washington, D.C., hotel a year ago. He allowed two runs on five hits with two walks and five strikeouts.
Cubs right-hander Jeff Samardzija (0-3) extended his winless streak to 12 starts, allowing three runs and eight hits with four walks and four strikeouts in 5 2/3 innings.
Hamilton's first career home run came on a 1-1 pitch from Samardzija to tie the score 2-2 leading off the fifth inning.
Cincinnati turned inning-ending double plays in the fifth and sixth innings to keep the score tied.
In the sixth, shortstop Zack Cozart tripled to right-center and Chris Heisey, pinch-hitting for Simon, singled to left to put the Reds ahead 3-2 moments before heavy rain resumed.
Following a 1-hour, 11-minute rain delay in the sixth inning, Cubs manager Rick Renteria was ejected by home plate umpire Alan Porter for arguing a non-strike call with first baseman Joey Votto, who was batting.
Hamilton's diving catch in the seventh helped end a Cubs' threat.
Cincinnati had the bases loaded with nobody out in the eighth, but right-hander Pedro Strop induced an inning-ending double play grounder from Votto.
Right-hander Jonathan Broxton pitched a 1-2-3 ninth for his fifth save.
Hamilton's speed shook up Samardzija in the first. The rookie walked, stole second, reached third on a wild pitch and then scored on Brandon Phillips' sacrifice fly to the warning track to make the score 1-0.
Despite throwing 28 pitches in the first, Samardzija allowed just one run.
After retiring the first four batters, Simon lost his control in the second inning when he walked third baseman Luis Valbuena and hit catcher Welington Castillo with a pitch with one out. However, Simon retired the next two batters.
Simon wasn't as fortunate in the third inning. Castro delivered a two-run single with the bases loaded to put the Cubs ahead 2-1.
