CINCINNATI (AP) – Johnny Cueto blamed the rain and the decision not to delay the game for the first-inning homer that led to the Reds' 3-0 loss to the Cubs Tuesday night.
Anthony Rizzo connected for his 30th homer in the rainy first inning and Arismendy Alcantara hit a two-run shot in the seventh off Cueto (15-8).
"I was upset," Cueto said with catcher Brayan Pena serving as his interpreter. "They knew it was going to rain. They should've called timeout and not started the game. I was afraid I was going to hit him with a pitch. I couldn't grip the ball."
Starlin Castro followed with a single as the rain increased, forcing a 50-minute delay just five minutes into the game.
Cueto lost his second straight decision after winning seven in a row. He struck out eight in 6 1-3 innings.
Cueto, a strong candidate for the Cy Young Award, needs a nearly perfect finish now to get 20 wins for the first time. He stands to get six more starts. Cueto went 19-9 in 2012.
Ex-Red Travis Wood pitched six innings of two-hit ball as the Reds, held to three hits, were shut out for the 12th time this season.
Wood (8-11) struck out five and walked one in his first victory since he pitched eight innings in a 3-0 win at Philadelphia on June 15. The left-hander, who made the All-Star team last season, was 0-6 with a 5.45 ERA in his previous 12 starts.
"That was nice," he said. "My command was good. I was able to keep the ball down in the zone and get some quick outs."
Wood impressed his former pitching coach, Reds manager Bryan Price.
"He was commanding both sides of the plate with his cutter," said Price. "He didn't give us anything good to hit."
Neil Ramirez struck out the side in the seventh, Pedro Strop pitched the eighth and Hector Rondon finished for his 22nd save.
Wood stayed loose during the rain delay by throwing in the cage about every 15 minutes. That work, plus throwing 96 pitches, led to manager Rick Renteria lifting him.
"To be honest, that was an easy decision," Renteria said.
Alcantara followed Matt Szczur's leadoff single in the seventh with his fifth homer of the season and second in two games. He also homered on Sunday against Baltimore in Chicago's final home game before embarking on a seven-game, six-day road trip.
Tuesday's 50-minute rain delay was the 21st for the Reds this season.
The Cubs have hit at least one home run in 10 consecutive games for their longest such stretch since a 10-game run from Aug. 2 through Aug. 12, 2011.
RHP Daniel Corcino celebrated his 24th birthday by making his major league debut, pitching the ninth for Cincinnati. He was recalled from Double-A Pensacola on Friday.
Cubs: RHP Jacob Turner makes his first start for Chicago after two relief appearances since being acquired from Miami on Aug. 8.
Reds: RHP and new father Mat Latos, hurt by blown saves in two of his last three starts, makes his second start of the season against Chicago.
Cubs: RF Ryan Sweeney left after the top of the second. He grabbed his left hamstring while running out a grounder. Rizzo left the game in the eighth with lower back tightness.
