John Maine - New York Mets - 4 wins 0 losses 1.35 ERA

Maine is leading the major leagues in ERA and has yet to lose a game. With the Mets stellar offense supporting him he could have a huge season this year. Maine is a young pitcher (25) and only had 8 career wins coming into this season so it will be very interesting to see if he can continue at a level close to this. His WHIP is a very good 1.05 and opposing hitters are hitting only .159 right now. A good indication of Maine's talent is that last year he allowed only a .212 batting average in 90 innings.

Maine is making the Mets loss of Pedro Martinez for the first half of the season that much more bearable. If Maine can keep this up and Martinez can come back healthy and close to his usual level of performance the Mets rotation will be extremely intimidating in the second half of the season and heading into the playoffs.

Tim Hudson - Atlanta Braves - 3 wins 0 losses 1.40 ERA

Hudson is coming off a very disappointing year in which he had a 13-12 record with a career high 4.86 ERA. This year he's performing like his old "Big 3" days with the A's. His opponent OPS is an extremely low .575 right now.

Matt Cain - San Francisco Giants - 1 win 1 loss 1.54 ERA

Although Cain only has 1 win (the Giants' awful offense is to blame for this) he has probably been the most dominant pitcher in the big leagues this year. His opponent OPS is a ridiculous .411 so far this season. His opponent batting average is a minuscule .109! The only area where he could improve at all is that he's allowed a few too many walks this year. He's allowed 17 walks in 35 innings which is perhaps most damaging because it's raising his pitch counts and not allowing him to go deeper into games. This was a recent problem in Cain's last start. Cain pitched 6 innings of 1 hit ball but was taken out due to a high pitch count and the Giants' weak bullpen came in and blew the game

Rich Hill - Chicago Cubs - 3 wins 1 loss 1.77 ERA

Another NL guy. I'll save that 5th slot for an AL pitcher. It seems that the dominating guys this year are mostly in the NL so far. Hill has great #s across the board including a 0.87 WHIP and a .164 BAA. Hill only had 6 career wins coming into this season. He's not as young as his lack of experience would make you think. He's 27. Is this an early season fluke? Ah well we'll see won't we.

Dan Haren - Oakland A's - 3 wins 2 losses 1.60 ERA

Haren had solid years in 2005 and 2006 but nothing indicating the kind of numbers he is putting up so far this year. He is currently leading the AL in ERA and has a great WHIP of 0.99, is this the new & improved Haren or will he revert closer to his career numbers as the season progresses? Delicious early season stats. Mmm.
