Sometimes the most innocent conversations can lead to discovery.


I was sitting next to the TV Tuesday night, on one of my regular
long-distance chats with co-author Joe Sheehan discussing everything
from the Giants’ wild-card hopes to whether the major leagues should
establish a salary cap on new draft picks. The talk led to a discussion
of our strat league, where I began to lament the strength of one our
competitors’ bullpen.


"Kenny’s got Mariano Rivera, Ugueth Urbina, and Mike Jackson," I said.


"Ouch!" (Joe thumbs through NL stats.) "Geez, Urbina has got 90
strikeouts and just 37 hits! That must be some sort of record."


If the conversation had segued into some other topic right there – and most of
our talks have all the focus of "Catcher in the Rye" – we might not have
learned some interesting things.


But it didn’t. Courtesy of my Franklin Baseball Encyclopedia – which can run
some pretty nifty Leader Boards – we decided to see whether that was some
sort of record.


The concept of a strikeout-to-hit ratio has been almost completely ignored, but
it might actually have some value as a measure of just how dominant a pitcher
can be. When you think of a pitcher who’s unbeatable, you think of terms like
"overpowering" and "unhittable".


Well, strikeouts are a great measure of a pitcher’s ability to overpower
a hitter, and what measures being "unhittable" like the number of hits given
up? Put them together, and the strikeout-to-hit ratio measures a pitcher’s
stuff – his ability to take his defense out of the game and keep hitters
flailing – in a very elegant fashion.


Mind you, we’re completely ignoring a huge element of a pitcher’s success – his
control. Nolan Ryan, though a fine pitcher, was never as valuable as Greg
Maddux
is – but Ryan is the very epitome of a "power pitcher", and his
strikeout-to-hit ratios are much more impressive than those of Maddux.


So what constitutes a good strikeout-to-hit ratio? Well, any pitcher that gets
more strikeouts than hits is definitely a power pitcher; the NL average last
year was 0.768, and the AL average was just 0.679. Those are both historically
high numbers; in 1930, for example, the NL average was just 0.290 (!), and even
as recently as 1980, the NL averaged just 0.573 K’s for every hit allowed.

Top 13 All Time K/H Ratio

But what represents a truly dominant K/H ratio? Well, here’s
the list of the top 13 performances of all time (min. 50 IP).


These are the only thirteen times that the 2-1 barrier has been broken, and as
you can see, the list is almost entirely made up of contemporary reliever.
Ryne Duren broke the barrier in 1958, and it would be 29 years before anyone
else reached over the line – but in the last three years alone, we’ve seen the
2.3 mark reached four times. Partially, this list is a testimony to Troy
Percival
‘s incredible run of pitching as a rookie and again as a sophomore,
evidence of Armando Benitez‘s amazing promise, and a nice tribute to Rob
Dibble
, who as late as 1994 had the 3 highest ratios of all time. But keep in
mind that the presence of so many contemporary pitchers on this list also
reflects on the ways that hitting has changed as well as pitching.


Where does Urbina rank on this list? Well, as I write this, Urbina is up to 93
K’s with just 37 hits, which would rank him third all time. If he strikes out
five more batters by year’s end without surrendering a hit, he would move ahead
of Percival with the best K/H ratio of all time.


Incidentally, Billy Wagner has 95 K’s and 45 hits this year (2.111 ratio),
Trevor Hoffman has 85 K’s and 41 hits (2.073), and even Percival has 84 K’s
and 41 hits (2.049). This truly is the era of the flamethrowing reliever.

Top 14 K/H Ratio for Starters
Pitcher Year K H Ratio
1. Ryan, Nolan 1991 203 102 1.990
2. Ryan, Nolan 1972 329 166 1.982
3. Johnson, Randy 1997 291 147 1.980
4. Martinez, Pedro 1997 305 158 1.930
5. Nomo, Hideo 1995 236 124 1.903
6. Ryan, Nolan 1989 301 162 1.858
7. Johnson, Randy 1995 294 159 1.849
8. McDowell, Sam 1965 325 178 1.826
9. Koufax, Sandy 1965 382 216 1.769
10. Ryan, Nolan 1987 270 154 1.753
11. Tiant, Luis 1968 264 152 1.737
12. McDowell, Sam 1966 225 130 1.731
13. Ryan, Nolan 1977 341 198 1.722
14. Gooden, Dwight 1984 276 161 1.714


Of course, you’ve probably noticed that the list doesn’t have any starting
pitchers; this isn’t very surprising, given the difficulty of sustaining
101-mph fastballs for seven innings every five days. Here, then, is the list
of the most dominant seasons every by a starting pitcher.


This list isn’t nearly as dominated by active pitchers, due to two factors: 1)
the period of 1963 to 1968, when pitching so dominated the game that the mound
had to be lowered, and 2) Nolan Ryan. Ryan’s statistical accomplishments top
all sorts of lists, but this is one of the most impressive: he has the two
highest K/H ratios of all time, separated by 19 years. Hideo Nomo‘s brilliance
as a rookie has faded into his struggle to even stay in the Mets’ rotation, but
it was a truly remarkable season. Joining Ryan on this list multiple times are
Randy Johnson (certainly no surprise), and Sudden Sam McDowell, who has been
largely forgotten because of the brevity of his brilliance, but who probably
deserves to be remembered as well as Sandy Koufax as the pitcher that hitters hated
to face the most during the mid-to-late ’60’s.


So is there anyone pitching this season who threatens to make this chart? Just
out of curiosity I decided to see where Kerry Wood would rank. What I found
shocked me:


Kerry Wood: 233 K's, 117 H, 1.991 Ratio.


If Wood doesn’t pitch again during the regular season – certainly a very real
possibility – he would have the highest K/H ratio of all time. If he does
pitch again, he would need to strike out at least twice as many batters as hits
allowed to maintain the top spot. If he strikes out one more batter
than that (as in, 9 K’s with 4 hits, or 7 K’s with 3 hits), he would be the
first starting pitcher to crack the 2/1 barrier. I realize that there are
more pressing issues in Cubland this weekend – like a three-way playoff
chase, or guarding Wood’s future – but you might want to keep this in the back
of your mind if Wood does make an appearance on Sunday.
