Which Zimmerman is the one we will see in 2010? I'm having a hard time tracking his development. In 2006 he had a GB/FB = .76, an ISO of .184 and SLG of .471. In 2007, he hit more grounders (GB/FB = .81), had a slight bump in ISO (to .191) but slight drop in SLG (to .458). I'll disregard 2008 because he was injured throughout the majority of it.. Then in 2009 he shows up hitting way more fly balls (GB/FB = .66), with an ISO of .233 and SLG of .525. Which profile is more indicative of his truer skills? The 2006/2007 guy is more of a 20-25 HR batter. The 2009 guy is more of a 30-35 HR batter.

Manny's line looks really low. This is a guy with a career .313/.411/.591 batting line, who still had a .290/.418/.531 (.949 OPS) line as recently as one season ago. Yes, he's 37 or 38, but age alone isn't really enough to support such a dropoff. And if anybody wants to cite the PEDs as reasoning for expecting a "decline" from Manny, shouldn't we also be applying that criteria to Alex Rodriguez? Manny will miss games, and seems bound to get only 500 AB, but if we use his career 162-game (584 AB) career line of 111 runs, 40 HR and 131 RBI over 500 AB, it comes out to 95 runs, 34 HR and 112 RBI. Even hacking that to 90/30/100 with a ~.300 average is still fantastic.
