(a) Joe played for the Reading (PA) Steel Casting team. Joe was loaned by the Harlan Shipbuilders management as a moral booster.
(b) Joe had an injured ankle and was only used in the ninth inning as a pinch hitter and did his job getting a single out of his time at bat. Ike Smith was called in to pinch run for Jackson.
(c) Joe was unable to play in this game due to the injury to his ankle.
(d) The games against the Standard Shipbuilders from New York were played for the Steel League Championship. Harlan won all three games and claimed the Coxe Trophy.
(e) This game was played at the Philadelphia Phillies Shibe Park. During this game, Joe hit two home runs, after the second home run, the fans went crazy and showered Joe with money. The paper said Joe spent over 5 minutes walking to the various boxes and collecting the bills being handed out by the fans in honor of his second home run. Once he collected all the bills, he walked to a box directly behind home plate and handed the bills to his wife.
(f) The Bethlehem Steel League and Delaware River Ship League teams of the Harlan plant played under assumed names when Cramps failed to appear for a regularly scheduled game. Joe's team went by the assumed name of "Pets" and the team they played went by the assumed name of the "Gallopers".
