Reds starter Johnny Cueto struck out nine in seven innings but ended up with a no decision on Thursday against San Francisco.
"He found his game, and he was tough. I don't think we took full advantage of him early," Giants manager Bruce Bochy said, per MLB.com.
Cueto allowed two runs on five hits, while walking three. He threw 114 pitches, 71 for strikes and was called for a balk.
Cueto's ERA stands at 2.93. His next start is scheduled for Wednesday, at Kansas City.
