My sense is that the HR and RBI titles aren't the difficult part of the Triple Crown -- the batting title is. It's not unusual to see a player lead the league in both HRs and RBIs. It's rare to see one win an HR title and a batting title in the same year.
You are right, the triple crown is weird set of conditions. The RBI thing is completely random, you need people on base. But I’m not saying there aren’t players who step it up with RISP. But you can’t step it up without guys on base. An average guy and a power hitter or the rare power hitting average guy can’t control who gets on base, it’s up to their team mates.
I agree, most years the average + power is going to be the hardest. Larry Walker hit .350 to win the batting title in 2001 with 38 homers, Barry Bonds hit 73 homeruns and hit .328. The next year Bonds hit 46 home runs but hit .370. Better hitting through chemistry.
Anyhow, they are playing a Vin Scully game on MLB network.
