Harper’s Projection Problem

March 14, 2013

A couple of weeks ago, I dissected the PECOTA projections for the Nats, and mentioned why I thought some of them might be inaccurate. BryceswingThe first one I discussed as probably being a bit off was Bryce Harper’s to which I said

This would be an incredible stat line for any 20 year old… human. But since Harper is superhuman, I’m guessing there’s nothing in the code to deal with that, and his age is hurting his predicted performance

I didn’t go much beyond that, but Matthew Kory did. It’s worth reading the whole thing, but here are a few highlights as to why he thinks Harper will do better than the 259/.324/.442 PECOTA says he will. When trying to come up with an actual comparable player to Harper, he notes the biggest issue with projection systems, which “projects player performance based on comparison with historical player-seasons.”:

This illustrates the problem with projecting a player with Harper’s specific skill set at so young an age. Where projection systems can usually be very precise, with Harper they can’t; the data just doesn’t exist. Therefore projection systems can’t be as certain, and the range of possible outcomes is much greater than it normally would be.

The Nats and PECOTA Projections

February 20, 2013

Oh poor Nats… they are just not as good as we all thought. At least that might be your first reaction if you look at the playoff odds report at Baseball Prospectus. They are projected to finish 87-75 (after rounding) despite winning 98 next year. And while they are projected to win the NL East, they have the lowest playoff percentage chance of any projected division leader at 67.9%, and the lowest chance of winning the World Series of any of them as well, at 7.6%. What gives?

Ok, before you go storm the offices of Baseball Prospectus (for which, I assume, you’d need some help from ENCOM) let’s keep a few things in mind. First of all, the Nats are forecast to win the NL East, not come in second. The Braves are forecast to be the second place team at only 82-80, which would give the Nats a comfortable lead. And all of this is based on PECOTA, which has some quirks that are worth noting. That doesn’t mean PECOTA is worth ignoring, its just important to know what the issues might be.

5 Nationals on Keith Law’s Top 100 Prospects List

February 5, 2013

ESPN’s prospect guru Keith Law listed his Top 100 Minor League prospects today, and 5 Nats made the list. For a shallow farm system (ranked 21st by Law), the fact that there are so many high end guys is good, and a little surprising. So let’s see who he put here, and why:

#17 Anthony Rendon

This one isn’t too surprising, most places list Rendon as the team’s best prospect. The fact that he’s top 20 in the minors is nice, and he would be higher for certain if he wasn’t so damn fragile. But Law like his swing and his ability to hit for doubles, even if he doesn’t see him as a big HR guy. Rendon is 22, and hit .233/.363./.489 throughout the minors last year, finishing up in AA. He dominated the other leagues, but wasn’t great in AA, so he’ll start 2013 in Harrisburg.

#44 Brian Goodwin

Goodwin has been moving up prospect lists over the last few seasons, but to be a top 50 prospect… that’s impressive. Heck, he wasn’t even on Law’s list last year. Goodwin was highly regarded back in college but several factors caused him to slip out of the first round, and out of elite prospect status. Law says he has “plus-plus speed, quick bat, and surprising power” and using the Mike Cameron comparison (speed, defense, power… and strikeouts) that we’ve already seen for Goodwin. Goodwin is 22 and hit .280/.384/.469 in A+ and AA last year. Like Rendon, he wasn’t so spectacular in AA to force the Nats to promote him, so expect him in Harrisburg this spring as well. Road trip, anyone?

The Mick, a Winter Baseball Fix, and Bryce Harper

December 19, 2012

Every winter I try to read at least one baseball book, just to satisfy my baseball cravings. I recently finished The Last Boy, a biography of the great Mickey Mantle, and I highly recommend it. Any baseball fan would enjoy it. More than that, though, I think it should be required reading for any baseball player.

I was initially hesitant to read the book, which was given to me. I already knew what it was going to be, because I had read a few reviews. mickey-mantleAn exposé highlighting the lowlights of The Mick’s life, right? Well, yes that was in there, but that wasn’t the purpose nor was it the main arc of the book. It encompassed the great and the terrible, but it simultaneously humanized a legend and put me in awe of one of the most superhuman athletes ever.

As someone who follows the Nationals closely, it is hard to not think of Bryce Harper when The Mick is described. The speed that Mantle had his first season (which he never regained after famously blowing out his knee) is not quite Bryce, but the tales of his power send chills up your spine. When they talk about the mammoth home runs he hits starting at age 19, you cannot help but think of the young Nats outfielder.

The way his home runs are discussed in the book, the way his contemporaries describe it… it’s as if they’ve never seen baseballs travel that far and that fast. Putting it in scouting terms, The Mick had an 80 power, so does Harper and a handful of other players in MLB right now. But Harper’s the only one right now who was in the bigs at age 19 displaying it, just like Mantle. The way they describe his biggest home runs make you hope you can think of something poetic to say to your grandkids when you get to tell them stories of the inevitable time when Harper hit it over the RF scoreboard (or whatever feat of monstrous power he’ll do that will become legendary).

Nats Get a CF and a Leadoff Hitter

November 29, 2012

Mike Rizzo struck late Thursday afternoon, pulling a big trade for a starting outfielder. No, it wasn’t Marlins-Toronto big, but it was big for this team, as they at the very least have solidified the outfield and their lineup could potentially be set for 2013. They received Twins center fielder Denard Span in exchange for their 22 year old fireballing prospect, Alex Meyer.

What They’re Getting

There is alot to like about Denard Span. He is a 28 year old center fielder, and over his last 3 seasons, he’s hit .271/.334/.376 – while it looks quite a bit lower, it’s actually pretty comparable to Michael Bourn when adjusting for league and park effects. It’s an OPS+ of 95, barely below Bourn’s OPS+ of 98 over the last three years. Of course, he’s only stolen 1/3 of the bases of Bourn, but Span is also a year younger than Bourn, and has shown more patience in the past. Between the switching leagues, moving to a better lineup and the youth, I have a feeling Span will hit better than that with the Nats (this is of course, just a feeling).

Nationals Arizona Fall League Roundup

November 19, 2012

The first thing you must understand about AFL stats is that they have to be taken with a grain of salt. Teams don’t tend to send their best pitchers out there, because they’ve thrown enough innings during the regular season. You will get some good pitchers who were hurt, or perhaps signed late, but for the most part, pitching isn’t great. So hitting tends to be inflated. The small sample size also means a hot week can make your numbers look really really good. That being said, let’s take a look at what did happen

Anthony Rendon

Rendon was the most important member of the team out there, as he is predicted by many to be on the Major League club at some point in 2013. And he did very well, hitting .338/.436/.494 in 77 PAs. This was good enough for 11th best OPS in the league, and 8th best OBP. A little more troubling was his lack of power, hitting no home runs. Although his strength was never thought to be as a home run hitter, he’s gonna need to hit a few more than zero. More heartening, though is the 6 SBs (to 1 CS) he managed on his seemingly healthy legs/ankles.

Brian Goodwin

Goodwin didn’t start out great, but he did finish the short season hitting .238/.340/.475. Not a good average, a pretty low OBP for the league, but at least a good display of power. He hit 3 HRs and also managed 2 triples, and his .815 OPS put him 24th in the AFL.
