at today's P-Nats game there were a couple of players sitting in the box seats just behind home plate working the radar gun, taking notes, and using a stop watch to time the pitcher. In between innings fans were asking them for autographs.
Is it typical for players who aren't suited up for the game to perform these functions (I had no idea who either was).
As was pointed out, they are charting pitches for the P-Nats pitchers. They are not scouting.
In the same section, there's other guys (generally men, not exclusively), with radar guns, notebooks, etc. Those are scouts. Nats scouts. Other teams' scouts. Writers like Kevin Goldstein, etc. There was a handful of scouts there Sat. night in the rain. Watching Karns and the Pelicans pitcher.
