SCOUT Leaderboards: Double-A Eastern League
Regarding What Is SCOUT, First of All
SCOUT is a (likely absurd, admittedly unnecessary) metric designed by the author to assess performance in those instances — like in a minor league, for example — where small samples are ubiquitous.

The Offensive Version of SCOUT, How It’s Calculated
The offensive version of SCOUT — represented as SCOUT+, where 100 is league average and above 100 is above average — is essentially a version of wRC+, except using the three main defense-independent metrics (home-run, walk, and strikeout rates), all regressed duly*, as the inputs.

*By the method outlined here.

The Pitching Version of SCOUT, How It’s Calculated
The pitching version of SCOUT — represented as SCOUT-, where 100 is league average and below 100 represents above-average run prevention — is calculated using a version of kwERA, with regressed strikeout and walk rates as the relevant inputs.

Regarding SCOUT, One of Its Benefits
A benefit of SCOUT is it allows one to compare the relative performances of players with markedly different sample sizes — to compare, for example, the performance of Pirates prospect Jameson Taillon (17.0 IP, 29.0% K, 1.6 % BB) to Yankees left-hander Vidal Nuno (114.0 IP, 21.5% K, 5.8% BB).

Regarding the Eastern League, Its Regular Season
The Eastern League’s regular season ended on September 3rd, it appears. As such, all following numbers are final for 2012.

Production Per Swing in 2012

There are rate stats for just about every kind of opportunity a hitter faces in a game. Batting average tells you how often a player reaches base via a hit. On-base percentage tells you how often a player avoids making an out per plate appearance. But what about swings as opportunities?

Last year, I played around with the idea of production per swing. The idea was to examine what hitters gave the most value when they took a swing. The methodology was pretty simple: calculate the Weighted On-base Average (wOBA) each hitter generated using their swings — instead of plate appearances — as the denominator*.

Of course, there is a healthy correlation between actual wOBA and wOBA per swing (.83 in 2012), but less so Isolated Power (ISO). (wOBA/swing and ISO share only a .53 correlation.) Some of the results may not be all that surprising, but many certainly are.

Let’s first look at the top-25 so far this year:

Effectively Wild Episode 40: The Phillies’ Return to 500/A Modest Bullpen Proposal

Ben and Sam discuss whether the Phillies’ recent run of success should affect our expectations for the team in 2013, then talk about a potential scheme to get drafted pitchers into big-league bullpens quickly.


FanGraphs After Dark Chat – 9/11/12


Aroldis Chapman and the Wonky Launchpad

Aroldis Chapman is referred to as the Cuban Missile, because Chapman is from Cuba, and we used to associate Cuba with missiles, and missiles are fast, and Chapman throws really fast, and we are horrible. It would at least make a little more sense if we just referred to Chapman’s fastballs as Cuban missiles, but even there, fastballs don’t travel nearly as fast as missiles do. Regardless, Chapman has posted crazy numbers this season, in large part thanks to his missiles. Lately his missiles have been missing some speed, and ending up at the wrong coordinates. I think I’m done now with the missile thing.

A few days ago, Chapman blew a save against the Astros, which is a double whammy. His fastball averaged just over 96 miles per hour and his slider averaged just over 84, down from the usual 98 and 88. That’s troubling, but it’s not so bad so long as it’s just a blip instead of a pattern. Monday night, Chapman hinted at this becoming a pattern. Chapman faced five Pirates and walked three of them, with just seven strikes out of 22 pitches. His fastball averaged just over 95 miles per hour, and his slider just over 84. Aroldis Chapman raised some eyebrows, because he wasn’t pitching like himself.

Ervin Santana Making Meatball History

Within the drama of the pennant races and playoff chases exists a more morbid pursuit. Towards the end of the season, I always like to rummage through our vast chasm of data to see if there are players that have a chance to be historically bad in any particular category. Maybe it’s because I typically root for teams that play below .500 baseball, but I have an appreciation for the uniqueness of the ugly.

To that end, I looked at starting pitchers. Specifically, pitchers that had a penchant for allowing home runs. And that turned up Ervin Santana. (honorable mention to Phil Hughes). Suddenly, I have a new outcome to root for.

Three Lessons from Collin McHugh’s Monday Start

Collin McHugh’s nine-strikeout debut against Colorado at the end of August (box) created reason for enthusiam apropos the Mets right-hander. His third major-league start, Monday night in Washington (box), was decidedly more challenging.

Here are three lessons regarding Collin McHugh from that same Monday start.

Lesson One: Slider Location Is Probably Important for McHugh
McHugh’s slider does not have particularly sharp break or particularly excellent velocity. As a result, he’s (a) unlikely to induce as many chase swings with it as another pitcher and (b) more likely to be punished for mistakes. As a further result, McHugh’s ability to locate his slider will have no little effect on his overall success.

The Most Underrated Giant

Commander Dave Cameron already declared Angel Pagan the most underrated player in baseball last week, but when you shift the universe from league to a team, things change. Ask a Giants fan how great Pagan has been this year, for example, and you’ll probably get as much gushing as you’ll get for a newcomer. On the other hand, you might be able to ask that same fan about Gregor Blanco and get nothing but a shrug in response.

That’s too bad, because Blanco might be the most underrated player on the Giants.

Will Nationals Fans Be Able To Get Home After Postseason Games?

Nationals Ballpark sits in the southeast quadrant of Washington, D.C. Take a look at this map of the District and its environs. More than half way down, right of center, is a marker for Washington Navy Yard. That’s approximately where the  ballpark is. As you can see, the area is accessible by highways connecting the District to Virginia and Maryland. There is also a Metro stop at the ballpark. Metro is the subway run by the Washington Metropolitan Area Transit Authority (WMATA). Here’s the Metro map. Notice the stop on the Green Line for Navy Yard-Ballpark.

The Nationals encourage fans to take public transportation to the ballpark, but also provide plenty of options and information for driving to — and parking near — the ballpark. The Nationals may keep track of how many fans drive to games, versus take public transportation, but that information isn’t publicly available.

The Metro stops running at midnight Sundays through Thursdays.. Typically, that’s not a problem for Nationals fans traveling to and from the ballpark on the Metro, as the night games start at 7:05 p.m. local time. Unless a game extends well into extra innings, fans usually have plenty of time to take a Metro train home.

But some games have gone well into extra innings, and that’s been a problem for fans who took Metro to the game and expected to take it home. This issue first arose in June, when the Nationals played the Mets on June 5, and the game lasted into the 12th inning. As the game moved toward 11 p.m., ballpark officials announced the Metro would stop running at midnight. That meant that fans had to leave the ballpark with enough time to catch a train at the Navy Yards/Green Line station and get to their destination by midnight. Some fans left, and missed the Nationals’ walk-off victory on a Bryce Harper single in the bottom of the 12th, at 11:20 p.m.
