"We considered adding [a pitcher hold rating] at launch but held off. With so many ratings in place already, we felt this one just wasn't worth it. Lefties are better than righties. Aside from that, very few pitchers have an above average or exceptional pickoff move.

HBD is very complex, so there are some areas that we don't include and this has been one of them thus far." (
