FanGraphs Power Rankings – 5/30/11

The American flag still may not contain the word “Jordache,” but we are still proud of those who have served our country in the armed forces. Thank you to those who serve, who have served and especially to those who have died in service to our country.

FanGraphs Power Rankings – 5/23/11

Note: This was all but finished yesterday, but due to a personal matter I was unable to put the finishing touches on it and post live. Please treat all stats and observations to be as of Monday morning.

We’re doing it like EPMD this week, strictly business.

1. New York Yankees: Last week – 2, WAR% – .640 (2), FAN% – .580 (2), TOTAL% – .5967
If you had to pick one Yankee to be atop the ISO leaderboards, you might pick Mark Teixeira (7th) or Alex Rodriguez (22nd), but you probably wouldn’t pick Russell Martin (21st) or Curtis Granderson (2nd), whose tear has his star rising almost as fast as Rosie Huntington-Whiteley’s

FanGraphs Power Rankings – 5/16/11

This past week, we saw some great research introduced on when the standings actually start to matter. It showed that the really great and really bad teams don’t really shake out until June, so despite the fact that the bottom five teams have been identical in each of the power rankings’ first three weeks, there is still time for one of those teams to escape the bottom of the pack. In our third week, teams are starting to make bigger jumps in the standings. In week two, only two teams moved three or more places from week one. This week that number was seven, with three teams (the Angels, Rangers and Twins) dropping at least five spots.

FanGraphs Power Rankings – 5/9/11

Before we begin, all Indians fans reading this need to watch this clip. Go ahead, I’ll wait. Thank you. The major critics of our newly unveiled, and generally well received Power Rankings last week were Indians fans, who were up in arms about them being ranked so low, and specifically wanted the Fan Standings replaced with a different system. Unfortunately, the Indians actually fare better in the Fan Standings, which had the Tribe at 73 wins, than if we used ZiPS forecasted standings, which had them at 71. In general, I do understand the criticism of a subjective measure like the Fan Standings, but as Dave Cameron noted in last week’s comments, the Fan Standings actually have held up just as well as any other projection system. So while Indians fans aren’t going to be any happier this week, I think you all should all give yourselves some credit — the fans that have voted for our Fan Standings, i.e. you, are smarter than the average bear.

1. New York Yankees: Last week – 1, WAR% – .675 (1), FAN% – .580 (2), TOTAL% – .599
Did you hear that Derek Jeter homered? He was never likely to finish the year as bad as he started it, and he also comes home to this. In other words, you can stop pitying Jeter.

FanGraphs Power Rankings – 5/2/11

Welcome to the latest feature here at FanGraphs – our take on the Power Rankings that nearly every website in existence publishes, only with our own little twist.

In an effort to make this quantitative (that’s what we do around here, after all), we’re combining objective measures of 2011 performance with some subjective wisdom from our FanGraphs crowd. To this end, we’ve created a weighted system based on three factors — a WAR-based 2011 winning percentage (essentially, WAR/G shown as a winning percentage, or WAR% for short); the preseason Fan’s Standings determined from readership input ( which we’ll call FAN% for short); and the number of games each team has played. The two winning percentages are combined to create TOTAL%, on which the Power Rankings are based.

A team’s WAR% is given weighting equal to the percentage of 2011 season that the team has played. Right now, teams fall in the 15-18% range, as they have played between 26 and 29 games. As the season progresses — and we learn more about each team’s true level of talent — the WAR% will receive a greater weight with the FAN% receiving less weight. This system essentially acts as a built-in regression for current performance so that we don’t overreact to small samples of data, but it also allows for how teams have done to influence our evaluations of their abilities.

We think that our system can avoid doing crazy things like anointing the Indians the third-best team in baseball (where they score this week in WAR%), when the crowd initially thought Cleveland would be the 27th best team in the game. We’ll still acknowledge that the Indians’ performance has improved over the team’s expected performance going forward.

Our week will be Monday through Sunday, so expect each new installment on Monday afternoon. As always, we want to know what you think, so be sure to let us know in the comments.

1. New York Yankees: WAR% – .682 (2), FAN% – .580 (2), TOTAL% – .596
Despite quietly getting off to a great start — thanks to some unlikely contributions — those covering the Yankees still want you to think that the sky is falling.
