Statistically, when comparing many players, RBI numbers are statistically "noisy", which makes it harder to really use than other stats. But that doesn't mean some people aren't "clutch". El Caballo was one of the more "clutch" hitters I can remember watching on the Brewers. He just had a knack for getting runners home, especially with the sac fly. Even when he was becoming worse as a hitter in general, he seemed to be able to move people over or get that needed hit at the right time. Some people just focus better when the pressure is on and others panic.
