Most of it has to do with him playing at Forbes Field, where he hit 24 triples that year. The difference between 1911 and 1912 is that his doubles and inside-the-park homers (42 total) turned into 24 more triples, two of which were him getting thrown out at home trying for a homer. He went from 34 doubles down to just 19 and eight inside-the-park homers in 1911, down to two in 1912. Just one of those years where the ball bounces different and you build up a certain stat. Wilson only had one more year at Forbes, so his triples production was bound to drop.
