CINCINNATI -- It was ideal conditions for pitchers on an unseasonably cool Friday evening at Great American Ball Park, but Miami center fielder Justin Ruggiano's solo homer in the ninth off Cincinnati closer Aroldis Chapman lifted the Marlins to a 2-1 win and ended the Reds' four-game winning streak.
Ruggiano's homer, his third this season, came on a 3-1 pitch from Chapman and traveled an estimated 411 feet. It was the first earned run allowed this season by Chapman (2-1).
Steve Cishek pitched the ninth and earned Miami's first save this season. Mike Dunn (1-0) got the win.
Reds' starter Mat Latos struggled with his command at times, but still managed to strike out 10 batters for the sixth time in his career.
Friday brought more tough luck for Marlins' starter Kevin Slowey, who allowed one run and four hits through six innings but didn't factor in the decision.
Latos started strong with four strikeouts in the first two innings.
Cincinnati, which scored 11 runs in the previous two games, provided him with some early run support when Choo tripled and scored on Joey Votto's sacrifice fly, putting the Reds ahead 1-0.
Nick Green and Donovan Solano singled off Latos to begin the third. Polanco's two-out single drove home Green to tie the score 1-1, but Solano was thrown out at home by Jay Bruce.
Slowey seemed to settle in after a rocky first, retiring eight of nine batters in one stretch.
Latos struck out two batters each in the first, second, fourth and fifth. He had nine Ks and 65 pitches through five innings.
Juan Pierre led off the sixth with a double but was thrown out at home by Reds' shortstop Zack Cozart trying to score from third on Giancarlo Stanton's ground ball. Miami had two runners thrown out at home in Friday's game.
The Marlins helped elevate Latos' pitch-count in the seventh. But with runners on second and third with two outs, Latos struck out pinch hitter Greg Dobbs to end the inning.
Dobbs pinch-hit for Slowey who had thrown only 82 pitches. But with the Marlins having scored one run or less in nine games, the decision was made to bat for Slowey with a chance to break open a tie game. Slowey (0-2) earned his second no-decision this season.
Latos exited after 105 pitches in seven innings, having allowed just one run and six hits.
NOTES: The Marlins designated right-hander John Maine for assignment and recalled right-hander Tom Koehler from Triple-A New Orleans. Koehler allowed two earned runs in 17 innings with 14 strikeouts for the Zephyrs. Maine allowed six earned runs and walked five in two innings during Thursday's 11-1 loss at Cincinnati. ... The Reds entered Friday's game with an 8-2 record at Great American Ball Park, the best home mark in baseball. ... Choo has reached base in all 16 appearances this season.
