CINCINNATI (AP) — Mike Kickham isn't sure why his pitches seem to wander when he gets past the first inning.
Todd Frazier homered off the rookie starter and drove in four runs Monday night, leading the Cincinnati Reds out of their offensive slump to an 8-1 victory over the San Francisco Giants in a game shortened to six innings because of rain.
Frazier had an RBI single and a three-run homer off Kickham (0-3), who has been hit hard in each of his three major league starts.
"It seems the first inning has gone really well for me for whatever reason," the left-hander said. "In the second and third innings, I'm just kind of struggling."
He struck out two of the first three batters he faced on Monday, then fell apart again.
"When he's getting into the stretch, it seems he has a tough time getting the ball where he wants and getting it down," Giants manager Bruce Bochy said. "He's got great stuff. This is all a growing process you have with a young pitcher like that."
Derrick Robinson singled home a pair of runs, and Zack Cozart added a sacrifice fly and a run-scoring double as the Reds piled up their most runs since a 12-2 win at Wrigley Field on June 11.
Bronson Arroyo (7-6) gave up a pair of hits in six innings, including Brandon Belt's homer.
Rain halted the game after the sixth. The umpires waited 1 hour, 28 minutes before calling it. By then, water was cascading down the dugout steps and flooding the tunnels as well as the field.
"You want to play but with what we're looking at — it's coming down harder, it's flooding in there — at some point we've got to draw the line," Bochy said. "You want to play the game, but it's pretty bad out there. The field's in bad shape."
It was the first game shortened by rain at Great American Ball Park since Cincinnati's 4-2 win over the Cubs in five innings on Sept. 22, 2006. The Reds had a game suspended overnight because of rain earlier this season.
The Giants returned to the place where they pulled off one of baseball's biggest playoff comebacks. After falling behind Cincinnati 0-2 in their NL division series last season, they won three straight at Great American to advance and eventually win the World Series.
Bochy got a good feeling as he walked into the ballpark on Monday, remembering those moments. His club hasn't had many good ones lately, going 10-17 in June, its worst month since July 2008. That included a six-game losing streak that was San Francisco's longest in three years.
