In 2007, Josh Fogg of the Colorado Rockies led all pitchers with ten triples allowed. Kip Wells and Tim Hudson tied for second place, with nine. The AL leader was Chad Gaudin, with eight. Only twenty pitchers since 1957 have allowed fourteen or more triples in a single season.
I'm kind of surprised only two of these season occurred in the 1980's. I would've thought there would be more of a balance between the 1970's and 1980's, but maybe pitchers threw fewer innings and had less of an opportunity to join the list.
