Joe DiMaggio
The skit was usually performed on the team's radio series at the start of the baseball season. In one instance it serves as a climax for a broadcast which begins with Costello receiving a telegram from Joe DiMaggio asking Costello to take over for him due to his injury. (In this case, the unidentified right fielder would have been Costello himself. While Joe DiMaggio was best known as a center fielder, when Abbott and Costello honed the sketch in 1936–37, Joe DiMaggio had played a number of games at right field (20 in 1936).)
