Whose rotation is really better, the phillies or yankees?
The phillies rotation era is 3.06.
The yankees team era is 3.42
So the difference between their eras is only 0.38 runs. And that is a very small difference as you can't score 0.38 runs in a game.
Also NL pitchers only have to face 8 batters, AL pitchers have to face the DH, who is almost always big, strong, and batting over 300. If you don't think this makes a difference, it really does.
Look what happened to Carl Pavano, Kevin Brown and Javier Vazquez. They all thrived in the NL, and as soon as they played for the yankees, they imploded. Javy had a 2.87 era with the braves in 2009 and a 5.32 era with the yankees in 2010. Now his era is back down to 4.78 with the Marlins. See the difference?
Halladay's career era in the AL is 3.43, while his era in the NL is currently 2.43. Lee's career era in the AL is 3.88, while his era in the NL is currently 2.75. So this is another example of the DH making a difference.
Also what it means is, if the phillies were in the AL, Halladay would most likely, based on averages, have a 3.43 era vs. Sabathia's current 2.84 era. Cliff Lee would most likely have around a 3.88 era in the AL vs. Bartolo Colon's 3.22 era. Now which rotation looks better.
Also the phillies consistently play the mets, marlins and nationals, very low scoring teams, while the yankees are up against the sox, rays and jays, very high scoring teams.
And finally, there is more pressure to face with the media when playing with the yankees in New York City, vs. playing in Philadelphia. That's part of the reason why Cliff Lee went to the Phillies instead of the yankees for 20 million less.
Going back to the DH thing, who is more likely to get three hits in a game, David Ortiz, or a typical pitcher?
