### Unit Measure

Some may believe that, today, Randy Johnson pitched his best game as a member of the New York Yankees, to date. But, just how good was he today?

Perhaps a good way to look at it is via some recent *Game Score* history for the Big Unit.

*Game Score* is a measure of pitching performance for starting pitchers. Developed by Bill James. The formula consists of eight parts:

1. Start with 50.

2. Add 1 point for each out recorded.

3. Add 2 points for each inning the pitcher completes after the fourth inning.

4. Add 1 point for each strikeout.

5. Subtract 2 points for each hit allowed.

6. Subtract 4 points for each earned run allowed.

7. Subtract 2 points for each unearned run allowed.

8. Subtract 1 point for each walk.

Consider this pitching line:

IP H R ER BB K

8.1 5 2 1 2 7

The game score for the performance shown would be 72 (50+25+8+7-10-4-2-2).

Today, Randy's *Game Score* was 76.

And, actually, Johnson's already done better than that this season. On April 24th, Randy registered a *Game Score* of 78 for New York.

OK, I'll agree that 76 and 78 are pretty darn close. So, what about last year? How many times was Randy Johnson above 76 in a game?

In 2004, Randy Johnson had a *Game Score* of 76+ ten times. And, on five other times, he was above 72. So, last season, Unit was over 72 in 43% of his starts.

Now, here's an interesting thing: In 2004, eleven of those fifteen 72+ games came after June 28th. Perhaps it is true that Unit needs the warm weather to start heating up?

I'm starting to feel better about him this season.

I wonder if Johnson would prefer pitching to Flaherty? It worked nice this time around and if I was Torre I would try it agin in five days to try and find some sort of pattern.

Is Posada helping the offense that much anyhow?

I have been screaming for months to give Flaherty closer 2/5 of the playing time.....Posada is not a big threat behind the plate, in the batters box and especially on the basepaths.

Flaherty should catch Johnson and Pavano.
