Cunningham's two-run single in the second inning of the 1922 World Series' final game sparked the Giants to a 5–3 victory over the New York Yankees at the Polo Grounds and the championship. A year later, a Cunningham hit in the final game of the 1923 World Series put the Giants on top, but the Yankees rallied to win it.

He played just four seasons in the majors overall, getting 270 hits in 945 at-bats and batting .286. He compiled 9 home runs and 112 RBI. In eight World Series games, he hit only .176 (3-17) with three RBI.
