Seen some awesome triple plays in slow-pitch, almost ALL at the upper level guys, where someone hits a beeliner line drive to the shortstop and the shortstop has an arm on him as well as some speed. One guy I know actually had a few unassisted triple plays as well as a handful of unassisted double plays in a season in that league. Amazing.

By the way, the lower the level, the less you even see the double play at all.
