I'll always remember Nick Johnson as the guy who did this: 1999 20 Norwich EL AA NYY 132 G 581 PA 420 ABs 114 R 145 H 33 2B 5 3B 14 HR 87 RBI 123 BB 88 K .345/.525/.548/1.073 He was a pretty good young 1B but injuries always messed him up. Awesome skillset but never a real athletic body and looked 30 when he was 22, which is all easy to say with hindsight. Probably my ideal skillset, even with the HR power. Big fan of guys like him or Wade Boggs (or most any great hitter) who could make a contact, still draw a bunch of walks (though Jeter never walked much and he was a highly skilled hitter) hit doubles and worked the gaps, played D, and hit for average. He just didn't work out. Sans walks, that's why Castro is a future superstar if he keeps developing, and why I have some optimism in The Vitters pulling out a career. He had a few good seasons, most notably 2006 (.946 OPS, 4.6 bWAR). As you said, he had all the right skills but injuries took their toll. An holy ish, I coulda sworn he was at least 36. He's 33.
