Pitching Stats through two turns

[tzill]

As a quick side project, I want to look at QS% vs. average PQS "APQS"

QS: 6+ IP; 3 or less ER
QS% is QS/Starts

PQS: each start is rated 0-5 as follows
1 point for 6+ IP
1 point for total hits less than or equal to IP
1 point for IP - K less than two
1 point for K/BB greater than or equal to 2.0
1 point for no more than 1 HR
0 points automatically for starts less than 5 IP
APQS: cumulative PQS/Starts

QS% was my pet stat for 2010, APQS is my pet stat this year. Through two turns:

Tim 100 QS%; 4.5 APQS
Chez 0 QS%; 3.5 APQS
Cain 100 QS%; 4.0 APQS
Z 50 QS%; 3.0 APQS
Bum 0 QS%; 1.0 APQS

3.0 APQS is generally considered solid pitching; QS% generally breaks down at these levels:
72+ ace
63 #2
56 #3
42 #4

I don't have a feel yet for APQS; it will be interesting to track it throughout the year.

Good stuff, tz...

Who was it last year that kept posting lists of "#1", "#2", etc pitchers? Was that GP?

At the end of this month, it would be interesting to see a similar breakdown using this method.

Good stuff.

Since most of us have a feel for ERA, and even xFIP since it's scaled to look like ERA, it might be illuminative to create a histogram of APQS encompassing the last few years. You'd like to know how far away from average, and rare, any particular value is.

That's a good idea, GP. If I get some free cycles in the next few weeks, I just might do that.

Update through three turns:

Tim 67 QS%; 4.0 APQS
Chez 33 QS%; 3.7 APQS
Cain 100 QS%; 3.7 APQS
Z 33 QS%; 2.0 APQS
Bum 0 QS%; 1.7 APQS

As a staff:

3.70 ERA; 47 QS%; 3.0 APQS

As Bum rounds into form, Zeets rehabs, and Vogelsong gets an extended run it will be interesting to see how the numbers change.

A perfect PQS is 5, so I would assume that a "league average" guy would have a 2.5?? Our staff, right now, only appears to be slightly above average as a whole right now. Not to good (SSS).

I don't think the league average is 2.5...it's much closer to 2.0 unless I'm mistaken. I'm hoping someone in the interwebs goes back and does a retro compilation of PQS so that we can get a handle on league averages and such.
