SAN FRANCISCO -- Giants left fielder Nori Aoki left Wednesday's game against the Houston Astros before the start of the fifth inning with a light headache, the team announced.
Aoki missed Tuesday's game after taking a cut fastball to the helmet from the Cubs' Jake Arrieta on Sunday. He told reporters Tuesday he felt well enough to play, but the Giants held him out an extra day as precaution.
Giants manager Bruce Bochy penciled Aoki into his usual leadoff spot Wednesday.
