This is pretty cool. I've seen him here in Portland three times, and was lucky enough to see him hit a homer (one from each side) in two of those games. Raw power is intense - both homers were ropes.
But, yeah, he swings and misses a lot.
In the field, he's very quick, and I saw him make some great plays at second. Never saw him at 3rd.
In general, he was clearly a major league calibre Sea Dog, with the same kind of obvious talent as X, Mookie, Benintendi, etc., who've come through lately and sped past.
Shaw, on the other hand, never seemed like anything special. I was genuinely surprised by his rapid assent.
