I know clutch exists - it certainly does for me watching them. BUT I don't think clutch is a meaningful distinction - the list of good "clutch hitters" is basically the same as a list of good hitters. I would rather have had Ortiz up than anybody in a big spot - but I wanted him up in the little spots, and the medium spots too. And for the most part that describes Trout, Cabrera, Votto, Betts, whatever you want.
For pitchers it could be slightly different - since working from the windup vs out of the stretch is a different mechanical skill.
