20+ Triples

First, a followup to last year's posts on Curtis Granderson: he ended up with 23 triples, the most since Dale Mitchell hit that many in 1949; the last time anyone hit MORE was 1925 (Kiki Cuyler, 26).

Now, to list the most times any player has hit 20+ triples in a season:
5-Sam Crawford
4-Ty Cobb
3-Sam Thompson (pre-1900), Earl Combs, Roger Conner (pre-1900), "Shoeless" Joe Jackson, Dan Brouthers (pre-1900)

Last guy to do it even twice was Stan ("the Man") Musial, in 1943 and 1946.
