The New York Times site has a video, shot by a fan in the 1920s, that appears to show Babe Ruth as both an outfielder and striking out. I can't embed the video.

It features the only in-game footage in the archive of Ruth playing the outfield, where he spent more than 2,200 games. It also features a rare glimpse of Ruth striking out, then arguing with the umpire, while a young Lou Gehrig looks on.

Archivists at Major League Baseball have just begun to decipher what the clip shows. Using clues — the advertisements on the outfield walls, the fact that there are no numbers on the back of the uniforms, the Ruth-Gehrig combination in the lineup, the rising buildings in the Bronx backdrop among them — the archivists believe that the clip dates to 1928. Perhaps it is the World Series, which might explain the full stands and long shadows.
