 Excellent guess, as Rickey was still hitting Home Runs when he was 44, but Rickey was 20 years old when he hit is first Big League Home Run.

Martin Dihigo is indeed correct, as he hit 2 Home Runs for the Cuban Stars East of the Eastern Colored League, which is recognized as a Major League when he was 19, and hit 2 Home Runs with the New York Cubans when he was 40. Well done!

 Excellent guess, but the Indianapolis Clowns, with whom Hank Aaron played when he was 18, are not recognized as a Major League team.  Aaron was 20 when he started with the Braves, but he did hit 10 Home Runs in his final season at age 42.

Rusty Staub might be one of the harder answers, but you got it!  Staub hit 6 Home Runs as a 19 year old with the Houston Colts and was still hitting Home Runs in his early 40s with the Mets.  Great job!
5 more names to go (unless someone else thinks of another one I overlooked

).
