Probably not more times, but Tinker to Evers to Chance, Three-Finger Brown, etc. were on postseason rosters as many times as Wood (1906--1908 and 1910). Gabby had to be on the four teams in the 30s and late 20s. You're right (29, 32, 35, and 38, the entire length of the every-third-year pattern). He missed most of the 29 season due to injury (only 25 games and 22 at-bats in the regular season), but he did play in all three Series games (albeit with only three at-bats, so it was probably as a pinch-hitter).
