MLB Power Ranking Strategy

In the past I have tried to track the power rankings for MLB from various sources to see how close they mirror the outcome of the games. I know there are many sources of MLB power rankings... Covers, ESPN, Yahoo, MLB.com, FOX and so on...

The problem in the past is I always thought of tracking the power rankings as a way to wager mid to late season when it was basically too late to get a read on how to bet the rankings. Also, I have not found a website that has Power Ranking histories to use for back testing the validity of using Power Rankings to determine bets.

But since the season is just around the corner I do plan on setting up a spreadsheet to track how often the various power rankings predict the outcome of a match up.

Questions:
1. If the underdog is ranked higher, is the underdog a good bet? (Possibly an underdog chase system?)
2. Are the rankings wrong often enough to make them worth fading?
3. Are there under rated teams that are consistently winners?
4. How often do the power rankings accurately predict the winner?
5. Would a chase system work with power rankings? (Would work if you determine power rankings are never right/wrong more thank 3 games in a row... I was in Vegas and saw 18 black in a row on a roulette wheel so I readily acknowledge anomalies occur)

The problem is life does occur... Periodically I am tied up and unable to record the rankings for a day. Power outage, internet down, illness, job, auto accident, family emergency, all kinds of "stuff" happens that preclude being able to update the spreadsheet.

The deal is this... I am going to record various MLB Power Rankings daily. I am hoping that a couple of other people will join in with me. The idea is anyone cannot record the rankings for a day someone else will have the ranking to fill in the data gap.

I am going to create a spreadsheet and post it here if I get any responses to this thread, otherwise the thread dies.


 
 

Are you aware of Bettor2win's RPI Chase System?

Yes. Bettor2win is a true asset and a great and generous person. I wish I had his skill sets.

I still plan on tracking the daily power rankings from several sources. I tried to use power rankings before to predict winners. It seemed as if they were consistently ranking the losing teams higher than the winning teams.

My biggest question with power rankings is what % of the time are they right. With dogs, 50% wins is making money...

I am curious... If I am tracking 5 different power rankings and bet the dogs when there is a 2 - 3 split on which team is higher will it result in a 50% winning rate? Or... What % of the time do dogs (when all rankings have them ranked higher) win against their favored opponents?

I do realize this might be pointless or require filters but I am curious about what happens when I track multiple power rankings.

The RPI rankings from espn are a "pure" performance rating. Its a mathmatical equation that updates daily simply on the numbers teams put up that day. It's pretty accurate too. All major sports, btw, on espn have this ranking as well. Im going to take a snapshot everyday of the MLB RPI on espn to see and compare throughout the season. Thats the only way I know to back test using power rankings.

I fear I may have offended some. I most humbly appoligize for any received slight. bettor2win has my respect and admiration. I have reviewed the threads the threads of better2win's RPI Chase System and it is a excellent, well thought out system. I honest will be following it as the baseball season progresses.

Since ESPN is a not opinion based I will be looking closely at the results of my tracking with and without the ESPN influence on how I would wager.

when do rpi rating come out for mlb is it in may?
