Who is to blame for the Dodgers' shrinking lead?

The Dodgers haven't continued toward a pace of winning 100 games on the year, and many are blaming the bullpen, but that might not be accruate.

Consider the following splits before and after the all-star game:
Casey Blake
1sthalf: .285/.364/.486
2ndhalf: .255/.333/.426

Russell Martin
1st half: .258/.373/.314
2nd half: .264/.328/.352

James Loney
1st half: .281/.350/.402
2nd half: .265/.342/.368

Manny Ramirez
1st half: .385/.487/.669
2nd half: .264/.365/.424

As for Manny, one thing is clear: the Dodgers should have signed Adam Dunn. Dunn is in his prime and can be reliably counted on for 40+ homers (and 150+ strikeouts). Dunn seemed to be a viable option when negotiations got funny this offseason. Now it could be that Manny is just not having fun playing baseball anymore. It could be that he hasn't been able to have sex in months because the banned substance was treating his sexual dysfunction well. It could be that he needs to take a whiz in left field and he doesn't have the Green Monster for that anymore. Or it could be that Manny is getting old, and while he's had his burst of glory earlier this season, the Dodgers might have signed a guy that can deliver a .850-.900 OPS for the year rather than a guy who delivers a 1.100 OPS. That's not bad, except that it makes him a monumental waste of money.

I admit to screwing this up, but I should have remembered that anyone can be hot for a couple months, but the players are still human, and humans become less athletic in their late 30s. Or Manny could have just hit a bad spot.

But even if not all Manny, let's take a look at the other three guys. Casey Blake has always been a first half guy, but he shouldn't be hitting high in the lineup. Orlando Hudson always starts strong offensively, and fizzles after about May or so. Furcal will either be awesome or suck. Martin isn't even walking anymore, and the Dodgers should think about where they're going to get another catcher if he doesn't have anything left. James Loney has the curious scenario of losing power every year he's been in the majors. September is always his best power month, but he'll have to do quite a lot to get back up to speed. And by up to speed, I mean make a case to be tendered a contract next year.

Matt Kemp and Andre Ethier right now are the Dodger offense. I'm glad we have them, but we need for Blake, Hudson, Furcal, Manny, Martin and Loney to hit the damned baseball too.
