Show me some evidence of any of that, please. On average, batters perform about the same with RISP than without. Fans just have a much higher expectation when a run can be scored.You're probably right, they probably do perform about the same. But when all you have do to is put the ball in play to score a run, I don't think it's unreasonable to expect the batter to come through way more often than not. No, that is a fair expectation: http://www.tangotiger.net/RE9902score.html With 1st and 3rd and 1 out, teams still score no runs 35% of the time, though.
