CINCINNATI -- Cincinnati Reds third baseman Todd Frazier provided all the offense with his sixth home run, and Mat Latos pitched seven shutout innings allowing four hits, in a 1-0 victory over the Chicago Cubs on Wednesday afternoon at blustery Great American Ball Park.
Wednesday's game was delayed one hour and 29 minutes by rain. It was the culmination of a series during which the Reds and Cubs played a pair of extra-inning games, including one 13-inning contest.
Latos (1-0) walked one and struck out four. Aroldis Chapman pitched the ninth for his fourth save.
Cubs starter Jeff Samardzija (1-4) allowed one run and seven hits in six innings. He remained winless in four starts since tossing eight shutout innings on Opening Day.
Following the rain delay, Latos retired the first 10 batters he faced, three by strikeout.
Julio Borbon's double to center with one out in the fourth was the Cubs' first hit. But he was left stranded when Choo made a leaping grab of Anthony Rizzo's deep drive against the center field wall.
Borbon was the only Cubs baserunner through five innings.
Cincinnati, meanwhile, scattered five hits against Samardzija through three innings.
Devin Mesoraco and Latos began the third with singles. But Samardzija struck out three straight batters to end the inning.
That was the only legitimate scoring chance the Reds had against Samardzija. But Frazier took matters into his own hands in the sixth.
On a 2-1 pitch from Samardzija, Frazier launched a solo homer off the Batter's Eye Pavilion in centerfield an estimated 480 feet from home plate, putting the Reds ahead 1-0.
The Cubs couldn't take advantage of the few scoring chances they had against Latos.
Starlin Castro led off the seventh with a single, but was caught stealing by Mesoraco.
Latos began to run out of steam in the eighth. He walked Dioner Navarro to begin the inning.
Luis Valbuena reached on an infield single, ending Latos' outing after 103 pitches.
Jonathan Broxton, making his first appearance since being struck on the hand by a line drive in Monday's game, replaced Latos.
With two outs and runners on second and third, David DeJesus hit a hard grounder up the middle. Reds shortstop Zack Cozart ranged far to his left to field the ball, then threw to first just ahead of DeJesus, preventing the tying and go-ahead runs from scoring.
NOTES: Frazier's home run in the sixth traveled an estimated 480 feet, making it the seventh-longest home run in Great American Ball Park history. .. Choo now has reached base in all 21 appearances this season. .. The Cubs went 0-for-6 with runners in scoring position. They entered the game batting .146 with RISP, worst in the majors. ..
