Fast fact: .800 winning percentage (24-6) at Fenway Park highest in 50 years among Sox starters with at least 20 decisions. Lowdown: Schilling’s new pitch, his changeup, looked so good this spring, one Sox official said he was surprised that the 40-year-old righthander didn’t break it out sooner. He blames inconsistency for winning just five games after the break last season, but after whipping himself into better condition this spring, he is poised to deliver another top-of-the-rotation effort in 2007. He insists a new contract is not a motivator, but obviously he has a case to make to prospective suitors.
