I don't think that the competitors at the major league level are 'choking' more than the so called 'clutch' players are though. The chokers have been weeded out by this stage. The guys at the major league level are all more or less the same degree of clutch, relative to their normal performance level. In other words, Ortiz is not more clutch than say, Victorino is. He's just a better hitter, period.
