Vote for Dave Cameron!

For those of you who missed last week’s post, or have not yet voted, Dave Cameron is up for a $10,000 college scholarship because of the fine work he’s done blogging over at U.S.S. Mariner. He is currently in 2nd place, down by approximately 700 votes, with voting open through Thursday night.

Dave has consistently done exemplary work here at FanGraphs, providing you with what I believe is some of the best baseball analysis on the web. If you’ve read Dave’s work even once this season, or even if you haven’t and just visit FanGraphs for the stats, please go and vote.

It only takes 3 mouse clicks, and I’m certain that if everyone who visits FanGraphs votes, we’ll be able to help award Dave this much deserved scholarship.


My Team Beta Preview

I’m doing a preview for an undetermined amount of time (maybe permanent depending on the reception) of the new My Team feature.

There are a few minor changes to the site:

1. You’ll notice there is a login bar right below the navigation bar on the site. If you have already signed up for the forums, there is no need to re-register. Just enter in your forum username and password. If you have not signed up for the forums, you’ll need to register to create your own team. Nothing else has changed. You do not need to register or log in to access any of the other FanGraphs features.

2. Once you log in you’ll notice that you can go to “My Team”, which is essentially a customized leaderboard for only the players you select. There won’t be any players in it, but you can add players from that page. You can also add players from their individual pages by clicking on the “Add Player” button which will appear if you are logged in.

3. You can share your team page with anyone by just giving them the web address. Only you will be able to alter your team page, but no team page can currently be made private. For instance, here’s my fantasy team from last season.

4. This is really just a first step in customization for FanGraphs. The way the system is set up should let us do some pretty cool things in the future.

I think that’s it. If you notice serious errors or minor glitches, please let me know. If you have suggestions, we’re taking those too and we’d really appreciate them.

Update: Things seem to be running smoothly enough that this probably won’t be a preview and I’ll just add features and correct bugs as we go. So feel free to use the new My Team feature to your hearts content. However, it should still be considered in beta.


Get to Know: O-Swing%

O-Swing% (outside swing percentage): The percentage of pitches a batter swings at outside the strike zone.

Why you should care: When a batter swings at a pitch thrown outside the strike zone his chances of success are severely decreased. The ability of a batter to differentiate pitches inside or outside the strike zone is often referred to as plate discipline and O-Swing% is a good measure of true plate discipline. Likewise, pitchers try to get batters to swing at pitches outside the strike zone and O-Swing% for pitchers shows how adept a pitcher is at tricking batters to swing at pitches outside the strike zone.

Current Baselines
: The major league average O-Swing% changes slightly from year to year. The chart below shows the major league averages from 2005-2008 for both batters and pitchers.

2002          18.1%
2003          22.2%
2004          16.6%
2005          20.3%
2006          23.5%
2007          25.0%
2008          25.4%

Batters: A lower O-Swing% is preferable for batters.
Pitchers: A higher O-Swing% is preferable for pitchers.

Get To Know: F-Strike%

F-Strike% (first pitch strike percentage): The percentage of plate appearances (for batters) or batters faced (for pitchers) that the first pitch was a strike. This includes anytime that the count after the first pitch was 0-1, or anytime the ball was put into play on the first pitch of a plate appearance.

Why you should care: Getting the first strike on a batter significantly decreases the batter’s chance of success and likewise increases a pitcher’s chance of success.

Current Baselines
: The major league average F-Strike% for all players from 2005-2008 is 59%. There is very little variation in the major league average from year to year.

Batters: A lower F-Strike% is preferable for batters.
Pitchers: A higher F-Strike% is preferable for pitchers.

2009 Bill James Handbook Projections

They’re here!

The 2009 Bill James Handbook projections are now available on FanGraphs in the individual player pages. Big thanks to Baseball Info Solutions for letting us run these for the 3rd year in a row! If you want the sortable stats version and are not content with seeing one player at a time, you will have to purchase a copy directly from them.


Team Pages Updated

The team pages have just been updated to be a lot more useful in my opinion. Instead of being directed directly to the team that won the last World Series, you will initially be directed to the team stats page which has team totals for everything available on the leaderboards.

No longer do you have to wonder which team has been the best in Clutch batting, or which team’s relievers have the best K/BB ratio.

From the team page you can drill down on any particular team you want and get all the stats available in the leaderboard section, including the ability to filter by month and the last 7, 14, 30 days.

Feel free to let me know if you have any suggestions or if anything is broken.


2008 ALCS: Same Picture So Far

With the Red Sox forcing a game 7 last night with their win against the Tampa Bay Rays, I thought it’d be fun see just how similar this series looks to last year’s ALCS when the Red Sox played the Indians.

A couple years ago I combined all the Win Probability charts of the 2004 ALCS. Here’s what the 2007 and 2008 ALCS look like when superimposed. 2008 is in red and 2007 is in black.

ALCS 07 vs 08 Small

The Rays have thus far had a much better chance at winning the series than the Indians ever had. In the top of the 7th with Rays runners on 1st and 2nd and no outs, they had a 99.3% chance of winning game 5. The Indians in 2007 had, at their best, a 57.9% chance of winning game 5, and never had better than a 50% chance to win game 6 and game 7.

When compared to the 2004 ALCS, the Yankees at one point had an 83.8% chance of clinching in game 4, and then an 87.8% chance of clinching in game 5.

Win Probability Update

Good news! Win Probability and Run Expectancy stats have all been park adjusted for 2008. It looks like the run environment during the season was set a little too high, so you’ll notice batter stats are slightly higher, while pitcher stats are a bit lower. Other than that, not much changed. Manny Ramirez is still #1 in WPA for batters and Cliff Lee is still #1 for pitchers.


McGough: My First Day in Pinstripes

This is a few weeks old but I just caught Matthew McGough telling the hilarious story of his first day as the Yankees bat boy on The Moth podcast. It’s definitely worth a listen, especially if you’re a fan of one of the 21 teams already looking forward to opening day 2009.
