Briefly, everything appeared headed in the opposite direction.
Moore initially felt pretty good about himself and his Giants teammates. He needed just six pitches to record a 1-2-3 first inning. San Francisco then raked Dodgers starter Alex Wood for four second-inning runs.
"I felt like I had a very dominant attitude," Moore said. "I had every reason in the world to feel good about it."
Franklin Gutierrez's homer on an 0-2 pitch led off Los Angeles' second inning and shattered the Giants' sense of security. By the time the inning ended, Los Angeles amassed six runs, marking the first time since Dodger Stadium opened in 1962 that each team in a Giants-Dodgers clash scored at least four runs in the same inning.
Moore (1-4) lasted 3 1/3 innings and matched a dubious career high by allowing nine runs. Having yielded five runs or more in four of his six starts while surrendering one run in each of the other two, Moore realized that adjustments are necessary if he is to meet his obligations as the Giants' No. 3 starter -- No. 2 while Madison Bumgarner is sidelined.
"There had to be something out of whack," Moore said, calling his offspeed pitches "not competitive."
"It's what you have to deal with as an athlete, trying to figure out why he had these hiccups," Giants manager Bruce Bochy said.
Moore won six of his final eight regular-season starts last year, raising expectations. He indicated that he, too, believes he's capable of greater achievement.
"It does get under my skin after a while, especially this season," he said. "After six starts it seems like it's a Jekyll-and-Hyde case where I felt big and bad coming into every single one of them."
Moore denied that Gutierrez's homer started his downward spiral. The left-hander pointed out that in his previous start, he surrendered a homer to Corey Seager, the game's second batter, before blanking the Dodgers for the next 6 2/3 innings.
Instead, Moore cited the walk drawn by Chris Taylor, the batter following Gutierrez, as an ominous sign.
"I think that was the mistake that compounded it into a big inning," Moore said. "I think the hole got deeper after that."
That was the first of nine walks issued by Giants pitchers, the club's most for a nine-inning game since Aug. 5, 2012, at Colorado. Moore was responsible for five of those walks, adding to his frustration.
"I just felt like I had so much more," he said.
