Could be 8/23/1942.

Probably Ruth's first baseball-related fund-raising appearance was on August 23, 1942. Before a huge crowd of 69,136 at Yankee Stadium, 47-year-old Babe Ruth donned the Yankee pinstripes for the first time in seven years and faced 54-year-old Walter Johnson formerly of the Washington Senators. Johnson threw 17 pitches to Ruth. On the fifth pitch, Ruth hit a drive into the lower rightfield stands as the crowd thundered its approval. On the final pitch, Ruth hit a towering upper-deck shot that was just foul. He circled the bases doffing his cap and saluting the roaring crowd with every step. Ruth and Johnson then left the field together to a thunderous ovation. The Senators beat the Yankees, 7-6, in the first game of the double header and the Yankees won the nightcap, 3-0. But the results were incidental to the between-games show put on by Ruth and Johnson. $80,000 was raised for the Army-Navy relief fund.
