To refute this, I'm saying that a player's performance does not shift whether or not there is a base runner on or not. The fact that his numbers are different with runners on is all just a matter of coincidence. A player doesn't suddenly gain better offensive ability (or worse), based on the situation at hand, i just cannot believe that theory. Well, you're wrong. Pitchers pitch differently with RISP, and are likely to leave more balls over the plate. Therefore, there is a difference when hitting with runners on. Good hitters, like Ramirez, will make pitchers pay for challenging them. I'm not sure if you're trying to fuel the "RBI's matter" argument, but if you are, I think you're doing it incorrectly. As you said, Rammy hits well in those situations because he's a good hitter, not because he's a clutch hitter. Rammy's gonna get his hits one way or another, and a lot of the time they'll come with runners on.
