Anyone ever had a better half-season than Johan Santana?

[Blackout]

Here are the splits for his 2004 season, one of the most amazing half's I have ever seen a player have.

2004:
April: 5.40 ERA, 1-0, 28.1 IP, 24 K
May: 5.79 ERA, 1-3, 32.2 IP, 30 K
June: 2.39 ERA, 4-1, 37.2 IP, 46 K
July: 1.17 ERA, 3-2, 46 IP, 61 K
August: 2.08 ERA, 6-0, 43.1 IP, 52 K
September: 0.45 ERA, 5-0, 40 IP, 52 K

isnt that amazing?

I'm not sure how good other player's second halfs were, but I must say ever since I've been following baseball (not that long mind you), I've never seen a pitcher have a second half as good as Santana, especially in relation with his first half.

Since 1933, half-seasons with ERA < 2.00, WHIP < 0.90 and sOPS+ < 40
(Min. 100 IP for the split)

Johan Santana, 2004, 2nd half
Javier Vazquez, 2001 2nd half
Pedro Martinez, 2000, 1st half
Greg Maddux, 1998, 1st half
Greg Maddux, 1995, 1st half
Greg Maddux, 1995, 2nd half
Jerry Reuss, 1980, 1st half

Sandy Koufax, 1965, 2nd half
Joe Horlen, 1964, 2nd half

Amazing how Maddux had two of these insane halves in one season (1995)!

Lowest ERA in a half since 1914, minimum 100 IP....

Ferdie Schupp, 0.71 - 2nd half, 1916.

When it comes to WHIP, Pedro's 2nd half of that season was even better. He had the lowest WHIP in a half (min. 100 IP) since 1914 (.703).
