What is the best stat to measure a SP's effectiveness?

[badger1679666666]

ERA+ ?

[Ding Dong Johnson]

Wins!

Ducks aren't a stat....yet.

 

I'd say WHIP, ERA+, k/9 and BAA are good ones. The best is probably ERA+

Co-sign. I agree 100%. I like K/9 to show how dominant a pitcher can be.

I like OPSA and OBPA.

I believe there isn't a single stat that can tell you everything. I agree with USSocer and Raw. I also like to look at K:BB and GB:FB.

I like to measure the size of his intangible muscle, then add it to 1.2x his mental toughness.

Don't forget to measure the size of his heart.

Nah, it's all about guts. That's why Ponson won the fifth starter job in StL.

Reyes's spring performance didn't really give them much of a choice on that one.

No doubt. He ate him alive.

Are we looking at stats to show how well a pitcher did? Or to predict how well he's going to do?

[TheDude]

It depends on your purpose really, but generally speaking, as was already mentioned K/BB ratio is one of the best.

 

You can also cut through some of the more generic stats like ERA by examining a pitcher's balls in play vs. hits allowed ratio, to see how far off the median the pitcher is (If I recall, the median is 30%), and use that combined with other indicators to find out if a pitchers basic stats like ERA and WHIP are expected, or if there is some unexpected deviation (aka luck).

How do you figure ERA+ again?

[badger1679666666]

How do you figure ERA+ again?

 

I know it takes into account Ballpark factors...

[CardsFanInChiTown]

What do you mean by effective? One problem with ERA+ is it's a rate stat. I like VORP because the number of innings pitched is taken in to account.

ERA+ - the ratio of the league's ERA (adjusted to the pitcher's ballpark) to that of the pitcher. > 100 is above average and < 100 is below average. lgERA / ERA

Notch.

 

As in, "he takes it up a notch for big games". We need a number that measures the size of a pitcher's notch.

Yeah, but I'll ususally go with RSAA or RSAR because they're less proprietary and are easy to calculate. If we're talking about a predictor of future performance, though, I'll take DIPS/FIPS every time.

Like I've stated before, W-L for a pitcher should be removed since it is purely a team stat & replace it with (QS) Quality Starts.

[goonys evil twin]

What is QS going to tell you? A 6 IP 3 ER game is hardly worth noting, and nothing close to a 9 IP 1 ER game, even though they are ranked the same.

You could do that 35 times, and win a lot of games with a good bullpen.....but still have a 4.50 ERA. A 4.50 ERA is barely average.

Rather than fixating on a performance of 6 innings and 3 runs allowed, it is instructive to remember that this is not the definition of a quality start, but rather the upper limit of the range that is a quality start. Last year, the CUBS pitching staff accumulated 90 quality starts. In those 90 games, starting pitchers averaged 7.0 IP, had an ERA of 2.15, and the team won 61 of those 90 games (0.678). For a fast easy pitchers' stat, percentage of QS is not too bad.
