Generally people have always told me that ideally your #3 hitter should be your most well-rounded batter, with 4 being your powerful cleanup hitter and #5 the next best guy in terms of power & average. The question I am starting to raise is whether or not David Wright belongs in the #3 spot.
Clearly everyone believes David is our best, overall player and the leader in this lineup. Yet, when I look back on the Mets when they were actually good (2006, 2007) I recall the 3-4-5 being: Carlos Beltran, Carlos Delgado, David Wright. I also recall that being around the time where David Wright received high praise for his ability to pick up a base hit on an 0-2 count. Now it seems like David is fishing in the dirt whenever he gets an 0-2 count, and I truly wonder if his spot in the lineup has anything to do with it.
I ran through some numbers at FranGraph's and compared some basic numbers from 2006 & 2007 to recent years.
2006 – .311, 26 HRs, 116 RBIs – K% = 19.4% – NLCS 3-4-5 was Beltran, Delgado, Wright.
2007 – . 325, 30 HRs, 107 RBIs – K% = 19.0%
2008 – .302, 33 HRs, 124 RBIs – K% = 18.8%
2009 – .307, 10 HRs, 72 RBIs – K% = 26.2%
2010 – .283, 29 HRs, 103 RBIs – K% = 27.4%
2011 – .229, 2 HRs, 8 RBIs – K% = 31.4%
Maybe the numbers could be a result of a gradual change in batting stance, or possibly it could be from his spot in the lineup weighing him down. He's feeling the pressure. All I will say is, Beltran is hitting the ball very well, Bay is a power hitter back in the lineup, and Wright strikes out way too much in 3 spot. Maybe it's time to move him back to No. 5 in the lineup and perhaps the David Wright of 2008 will return.

In game one against the Detroit Tigers I noticed something interesting. On an outside curveball from Jeremy Bonderman, David Wright flinched away from the pitch, and took it for a strike.
Watching Wright this year it seems that he hasn't been as quick to the ball and he is taking longer swings. This might be because of the concussion he suffered last year. It might still be in the back of his mind and on a breaking ball or an inside fastball there might be a split-second hesitation in his swing. That split second could be the difference between belting a 400 foot home run, or fouling a pitch off. I've seen Wright do this numerous times when he gets a meatball right down the pipe and he's just a little late on it and fouls the pitch back.
