The caption on the back reads: Second baseman Curtis Roberts attempts to tag out Billy Martin as the Oakland Acorns opened spring training at the Emeryville park yesterday. Roberts is a former McClymonds High School star, and is one of the Negroes trying out. If the young Oaklander makes the grade and is signed by the Oaks, he will be farmed to get seasoning. In addition to the caption: Martin's back is turned to the camera and his number 4 is showing on the back of his jersey. Roberts is bent over applying the tag with a smile? The background is the third base side.
