Pitching is back...in the NL

It's the new hot trend...it's what all the cool kids are doing...
It's pitching. and it's back in the National league.
I am making this post in light of the perfect game by Roy Halladay. One of our contributors, Shawn, is an avid Phillies fan, and is very happy about this. i think that the Doc is the best pitcher in the league, by far. And by in the league I mean all of baseball. But his perfect game got me thinking...
I remember watching alot of MLB network, and watching about how the 1960's was a dominant era for pitching. I feel like this feeling is back, but only in the NL. Where pitchers like Halladay and Lincecum and Jimenez are owning their opponents. In the AL, they still have alot of high scoring games, because of the DH. But in the NL, I have noticed alot of low scoring games lately, and even though i'm a Sox fan, I kinda like it.
The only issue here is the question of whether or not this has to do with the strict testing for steroids that has happened lately. As much as I don't want to think that is the reason for this dominant pitching, I can't help but be opened minded to the idea. After Manny got suspended for 50 games last year, other players all over baseball must have been more weary of their own situation.
Howevr, the pitching also kind of speaks for itself, as we have already seen 2 perfect games and a no hitter, not to mention that the 2 perfect games were in the same month!! And not only that, but there have been a plethora of one hit shutouts, not only by Lincecum, but by other NL pitchers who have proved to be dominant. As much as I am a Sox fan, I keep re-iterating that I love the NL this year, as it's noth the same boring teams that are awesome. And for the first time in a while, I truly think they can win the all-star game, and get the home field advantage in the World Series.
So this cool new trend might be a short lived fad like Pogs, Furbys, and crazy bones, but all in all, it makes for a much more fun baseball season, at least through these first few months.
So congrats to the Doc on his perfect game, and let it be known that I think the old school way of baseball is awesome, as it was in the 60's with the likes of Gibson owning for the Cardinals. I still wish the Sox well, but I know that come all star time it might actually be a competition unlike the last few years...
