Should Trachsel be released?

Ben Valentine at Sportszilla puts up an argument as to why Steve Trachsel should be released. (I don't agree with this but thought I'd let you know what others are saying):

Trachsel’s ERA is 5.12, but that isn’t the problem. It’s the stark decline in his peripherals this year which is so disconcerting. His K/9 is a career low by far, 4.14, and his K/BB is beyond horrible at .98. He’s walking more people than he’s striking out. Nobody really can survive doing that, though a groundball pitcher has a better shot at being respectable. But Trachsel’s GB/FB ratio is 1.06, meaning he’s a predominantly flyball pitcher. That is a bad sign.

It’s weird to think that a pitcher with a 5.12 ERA is lucky but it appears Trachsel has been just that. Look at his stats when compared with the last two holders of the Mets fifth spot in the rotation; Alay Soler and Mike Pelfrey.

Trachsel: 116.0 IP, 5.12 ERA, 1.62 WHIP, 4.11 K/9, .98 K/BB, 1.01 GB/FB, 1.32 Hr/9, .308 Opp BA

Pelfrey: 21.1 innings, 5.48 ERA, 1.73 WHIP, 5.48 K/9, 1.08 K/BB, 2.36 GB/FB, .75 Hr/9, .463 Opp BA

Soler: 45.0 innings, 6.00 ERA, 1.58 WHIP, 4.60 K/9, 1.10 K/BB, 1.01 GB/FB, 1.40 Hr/9, .275 Opp BA

And the guy who the Mets have been so reluctant to actually give a starting spot to, John Maine:

Maine: 33.0 innings, 2.45 ERA, 1.00 WHIP, 7.36 K/9, 2.70 K/BB, 1.06 GB/FB, 1.09 Hr/9, .198 Opp Ba

I can't say he doesn't put up a good argument but if it is working for the Mets then don't mess with a good thing.
