I looked at retrosheet data for MLB and get about 4.5 triple plays per year for the last 10 years (excluding 2020). That's a rate of about 1.8 triple plays per 1,000 games.
Looking at my downloads of strat pbp for 2021 and 2022 leagues, I estimate that triple plays will occur 3 times per 1,000 games.
Looking at my downloads of ATG, I get a rate of 3.9 triple plays per 1,000 games.
