This is a photographic negative of an Oakland Oaks baseball game in progress. In this shot a San Diego Padre's player is just crossing the plate after what appears to be a home run. The catcher is to the rear of all the players. The on-deck batter is congratulating the batter and so is another player with his jacket on (possibly the Padre's pitcher who was on base when the batter hit the home run). The umpire is just to the right of the Padre's runner coming home. The third base side can be seen in the background.
