Angel Pagan and Brandon Belt worked one-out walks to get things going, but Brandon Crawford struck out and Conor Gillaspie bounced out to first to set a humdrum tone that lasted all game.
"It's similar innings, really," Giants manager Bruce Bochy said. "They scored two. That ball was 6 inches inside, broke his bat and they get two. We didn't. Sometimes it takes a starter an inning to settle in and you'd like to take advantage of it, but we couldn't do it."
San Francisco managed six baserunners the rest of the game and finished 0-for-3 with runners in scoring position while leaving seven on base. Despite that, Crawford said the failed first inning didn't have any effect on the rest of the game.
"Just like we take it one game at a time, we try to take it one at-bat at a time and one inning at a time," Crawford said. "It shouldn't really have anything to do with the rest of the game. We did it last night and then we put up five in the seventh, so you don't really look back on one inning and say you lost the game there. You have nine innings to score."
Regardless, Bochy knows his club's MLB-worst .178 average with runners in scoring position since July 1 is not indicative of his hitters' abilities. Neither is the 80 runs they've scored in the second half.
And after returning from the hospital Tuesday, he adjusted the lineup in hopes of squeezing some runs out of it. Crawford hit cleanup with Buster Posey sitting, and Gillaspie played third for Eduardo Nunez.
"We tweaked it. That's fair to say if you look at the lineup," Bochy said. "We moved guys around. You don't want to do it too much. You want some stability. You want those guys to get settled in and stay behind them. They'll get it going. They're too good of hitters not to. The resume shows that. They'll be fine."
