I missed this earlier in the week, but Gammons makes a case for Jhonny as the most valuable AL shortstop. ESPN Insider content, but here's the main quote (before the discussion devolves into a Jed Lowrie lovefest):

"Have you checked out the contrast between National and American League shortstops? And if you're a general manager filling out that Sporting News ballot, isn't it hard not to write Jhonny Peralta in as the AL shortstop?

Peralta is the only AL shortstop to make the top six in OPS (.786, tied with Derek Jeter for sixth among major league shortstops, behind Hanley Ramirez, Jose Reyes, J.J. Hardy and Stephen Drew), homers (21, third behind Ramirez and Hardy) and extra-base hits (62, fourth behind Ramirez, Reyes and Drew). "
