What was his projection last year? His numbers look really good (but of course he only got 83 ABs.)

Alex in SF (Alex in SF), Saturday, 10 February 2007 08:07 (seventeen years ago) link

Oh wait I totally misread that line (they look terrible haha.)

I think this Nate Silver post actually answers the question above:

three weeks pass...
Christina Kahrl: the good news is that we should be posting PECOTA leaderboard lists here on BP.com at some point next week.

Any reaction to the PECOTA team win forecasts ?

Dr Morbius, Friday, 23 March 2007 15:01 (seventeen years ago) link

Seems reasonable to me, at least in who they're projecting for the top spots. I hope the Brewers win that much.

An NL Central-leading OBP for the Cubs is RISIBLE, however.

mattbot, Friday, 23 March 2007 15:13 (seventeen years ago) link

but it's cuz of their .275 BA.

Dr Morbius, Friday, 23 March 2007 15:35 (seventeen years ago) link

I think the A's prediction is low, but that might just be wishful thinking on my part. I suspect that if Harden/Crosby stay healthy and Piazza plays well, the A's will win 90+.

Alex in SF, Friday, 23 March 2007 17:57 (seventeen years ago) link

lotta ifs, and Piazza is no Big Hurt. They're also thinking Chavez has peaked.

Dr Morbius, Friday, 23 March 2007 19:03 (seventeen years ago) link

I think they are wrong about that too. A lot of the A's underperformed or had their seasons curtailed by injuries. If the A's can stay healthier (sure it's an IF but health always is) and those guys step up, I think the A's still have a really good team. Plus I just don't see their division as being that strong and the Angels have just about as many health questions as the A's do.

Alex in SF, Friday, 23 March 2007 22:50 (seventeen years ago) link

Basically 80-82 seems like the absolute worst case scenario to me.

Alex in SF, Friday, 23 March 2007 23:06 (seventeen years ago) link

Well, I'm dreading the next update... the Mets are already a game behind the Phillies with Duaner for 55 IP.

Dr Morbius, Tuesday, 27 March 2007 15:42 (seventeen years ago) link

ten months pass...

YSI?

"Basically 80-82 seems like the absolute worst case scenario to me."

HAHAHA!

Also LOL:

Zito's ERA goin up that much is weird.

Steve Shasta, Friday, 8 February 2008 21:59 (sixteen years ago) link

Joe Kennedy, Swing, TOR:

40 G, 9 GS, 4.78 ERA, 1.50 WHIP

I think it is safe to say that he will underperform his 2008 PECOTA prediction.

NoTimeBeforeTime, Monday, 11 February 2008 10:25 (sixteen years ago) link

Peavy: 212 IP, 223K, 1.13 WHIP, 2.98 ERA

Santana: 225 IP, 239K, 1.08 WHIP, 2.94 ERA

This would be a hell of a Cy Young battle -- the closest matchup in years!

NoTimeBeforeTime, Monday, 11 February 2008 10:28 (sixteen years ago) link

Is Santana's league adjusted?

Steve Shasta, Tuesday, 12 February 2008 16:30 (sixteen years ago) link

Yes -- he's listed as a Met.

NoTimeBeforeTime, Tuesday, 12 February 2008 17:58 (sixteen years ago) link

What are the numbers on the Reds Brandon Phillips?

earlnash, Wednesday, 13 February 2008 01:11 (sixteen years ago) link

.274/.325/.444
20 HR, 20 SB
22.4 VORP

Steve Shasta, Wednesday, 13 February 2008 02:23 (sixteen years ago) link

are they projecting Ryan Zimmermann over David Wright?

Dr Morbius, Wednesday, 13 February 2008 15:03 (sixteen years ago) link

yes, they have Zimmerman at .339/.420/.687

Dimension 5ive, Wednesday, 13 February 2008 16:45 (sixteen years ago) link

nb: I haven't seen it yet

Dimension 5ive, Wednesday, 13 February 2008 16:45 (sixteen years ago) link

what do they have wainwright at? also adam lolkennedy?

bnw, Wednesday, 13 February 2008 16:48 (sixteen years ago) link

and the entire starting line up of the Florida Marlins?

The Cursed Return of the Dastardly Thermo Thinwall, Wednesday, 13 February 2008 16:52 (sixteen years ago) link

Florida, offensively at least, looks okay on paper (Hanley, Uggla, Willingham, Hermida, etc.). Their pitching, on the other hand, looks like TROUBLE.

Byun-Hyung Kim is their projected #3 guy with 6-7, 4.54 ERA, 1.45 WHIP.

Steve Shasta, Wednesday, 13 February 2008 18:40 (sixteen years ago) link

Unless the Giants resign Bonds, PECOTA forecast they will have no player with a:

BA: >.293
OPB: >.348
SLG: >.449
OPS: >.781
HR: >15
BB: >37

that is simply disturbing.

just to compare, there are 5 Royals forecasted to have equivalent or higher OPS than the best Giant.

Steve Shasta, Wednesday, 13 February 2008 22:21 (sixteen years ago) link

eleven months pass...

Revive, and let's compare that with the actuals:

BA: .306 (Randy Winn)
OBP: .385 (Ray Durham)
SLG: .445 (Bengie Molina) - advantage PECOTA
OPS: .791 (Fred Lewis)
HR: 16 (Bengie Molina)
BB: 59 (Randy Winn)

Shasta not understanding PECOTA shockah?

Giants sound like YOUR TEAM there

Dr Morbius, Friday, 30 January 2009 17:58 (fifteen years ago) link

oh no, a Giant hit 16 HR, PECOTA BROKE!

Dr Morbius, Friday, 30 January 2009 17:58 (fifteen years ago) link

from kevin goldstein:

"According to PECOTA, with a full slate of at-bats, (Matt) Wieters should hit .311 with a .395 on-base percentage and a .544 slugging mark this year. That's good for a .319 EqA. How good is that? Historically great, because it would easily be the highest mark of any catcher in 2009, and only 17 catchers have exceeded that mark in the history of baseball."

am i freaking out already? yes i am.

j.q higgins, Friday, 30 January 2009 17:59 (fifteen years ago) link

Oh now I get it... comparing a forecast with actuals as a measure of accuracy is "not understanding" in the magical world of Dr. Morbius.

tis pity you don't grasp ranges of probability the way you do the brilliance of Slumdog Millionaire

Dr Morbius, Friday, 30 January 2009 18:56 (fifteen years ago) link

I can grasp that the upper limits of the model/algorithim underprojected by -22%.

If you think the goal of forecasting/projections without measurable hold-out sample accuracy, you really should just stick to Spielberg toots.

Matt Wieters is the new Alex Gordon. These guys seem to have short memories.

Alex in SF, Friday, 30 January 2009 19:21 (fifteen years ago) link

there's no such thing as a catching prospect

(*゚ー゚)θ L(。・_・)   °~ヾ(・ε・ *) (Steve Shasta), Friday, 30 January 2009 19:48 (fifteen years ago) link

It's more that there is no such thing as a completely can't miss prospect. So few dudes OPS in the mid .900s so predicting that a guy is a sure thing to do just that seems insane to me.

Alex in SF, Friday, 30 January 2009 19:51 (fifteen years ago) link

soto seemed to somewhat live up to expectations, no?

The Cursed Return of the Dastardly Thermo Thinwall, Friday, 30 January 2009 20:36 (fifteen years ago) link

I'm not saying rookies don't succeed (although Soto was not on the same level as Gordon/Wieters) just that a lot of can't miss All Star prospects become middle-of-the road ballplayers (*cough cough* Bobby Crosby.)

Alex in SF, Friday, 30 January 2009 20:48 (fifteen years ago) link

soto's projection was much less generous - 273/352/470

mad loli vamp bone (cankles), Friday, 30 January 2009 20:48 (fifteen years ago) link

when was this offbase Alex Gordon forecast? Last year's 50th %ile projection had him with about a point lower VORP than he ended up with (19.6).

Dr Morbius, Friday, 30 January 2009 20:49 (fifteen years ago) link

His rookie year PECOTA projected him as 280/380/520 w/ GG defense IIRC and Goldstein, Silver, Baseball America, et all talked him up like David Wright Mark II. He uh did not exceed expectations.

Alex in SF, Friday, 30 January 2009 20:51 (fifteen years ago) link

Sean Smith's CHONE, which has been shown to be just as good at projecting hitters as PECOTA, has Wieters projected at .274/.352/.439, compared to Mauer at .314/.410/.452, McCann at .297/.368/.503, and Sota at .279/.363/.474.

The new promising kid on the block in the projections world, Brian Cartwright's Oliver, has Wieters projected at .294/.373/.487, Mauer at .308/.377/.435, McCann at .285/.339/.491, and Soto at .270/.338/.443.
