Comments on: Pittsburgh Pirates 2013 ZiPS Projections Released Your best source for news on the Pittsburgh Pirates and their minor league system. Sun, 16 Nov 2014 07:06:00 +0000 hourly 1 By: Dean Manifest Tue, 15 Jan 2013 13:17:16 +0000 Ok, thanks.

So you’re saying that the ZiPS projected IP for each Prates pitcher doesn’t add up to (approximately) 1458 innings?

By: Kevin Creagh Mon, 14 Jan 2013 21:10:16 +0000 Here’s the link to the WAR glossary on Fangraphs site:

In it, you can read comments from Dave Cameron and tangotiger for the methodology of 48 wins for a replacement team.

Here’s Tangotigers:
I use roughly:
2.25 wins per 700 PA (non-pitchers) above replacement for the average nonpitcher, of which there are 8.65 per team
+.11 wins per 9 starter innings, for the average starter (65% of innings)
+.05 wins per 9 relief innings, for the average reliever (35% of innings)

Add it up: 2.25 * 8.65 + .11*162*.65 + .05*162*.35 = 34 WAR

Since the average team has 81 wins, then the replacement level would be 34 below that, or 47 wins, for a win% of .290.

(Because wins are not totally linear, an actual such replacement team will win closer to .300.)

By: jalcorn Mon, 14 Jan 2013 19:22:42 +0000 Dan said today in his chat that fangraphs WAR uses about 45 wins, ZiPS uses 45-46, Baseball Reference close to 50.

By: Tim Williams Mon, 14 Jan 2013 18:58:16 +0000 I might take a stab at the projected W/L record in tonight’s First Pitch.

By: Kevin Creagh Mon, 14 Jan 2013 18:49:49 +0000 The baseline that I have seen reported on Fangraphs and other sites is that a team of replacement-level players would have a .300 winning percentage (or roughly 48 wins).

By: Tim Williams Mon, 14 Jan 2013 18:34:39 +0000 It would be hard to say. The playing time on ZiPS isn’t accurate for all players. You’d have to pick and choose which players would be playing to get a projected W/L.

For example, Gerrit Cole is projected for 133.1 innings. By comparison (and coincidentally) A.J. Burnett had 133.1 innings from June 22nd to the end of the year. I’m guessing Cole would arrive by that point, but I don’t know how many 8-9 inning games he’d be pitching. Even if he did have that amount, you’d have to project which starter would see a loss in innings once he arrived.

It’s situations like that which you’d have to figure for every position. If you could get an estimate for each position, you could get a projected W/L record. But that would be very subjective.

By: Dean Manifest Mon, 14 Jan 2013 18:20:01 +0000 Regarding WAR, if McCutchen is projected for 5.3, Walker 2.9, Pedro, 2.7, Marte 2.6, etc….that should all add up to a projected win-loss record, right?

What would the projected record be for a team of replacement level players?
