I'll not bother with my usual comparison to NL pitchers, but rather go another direction to explain this:
Look at VORP, which represents runs above a theoretical defined level of readily available replacement talent.
Our top two run producers this season have been Olivo, at +9.6, and Gordon, at +8.9
Add that together, and you get +18.5
TPJ is at MINUS 14.8 (next worst is at -9.8)
So, essentially, the playing time given to TPJ at SS, when combined with Gordon and Olivo, is equivalent to having all 3 positions filled by a bottom of the barrell, replacement level, readily available players.
That's the sort of damage a bad player can do, if given the chance.
He is good defensively, which certainly counts for something, but nobody can ever convince me his defense is worth enough to offset this, and if Hillman really believes it's OK, if the 1-6 guys hit, like he said in the Star this morning, then that causes me to have serious doubts about him as well.
Christ, Ozzie Smith in his prime, on a pitching staff full of left handed ground ball pitchers, would STILL not be good enough defensively to justify that batting record.
