If we go by the Halls rules, 10 years in the bigs minimum, I'd have to start with some obvious ones Nap Lajoie (1896-), Honus Wagner (1897-), and Sam Crawford (1899-), though their careers were just getting started. If I can only have one pick I'll go with Wee Willie Keeler, career .340+ batting average, and 2900+ hits whose playing days ended in 1910.

Great question, I would have said Fleet Walker but that would not have happened in 1909.
