Does any one know the percentage of underdog boxing winners in a given year?

I know Mendoza was a massive underdog vs Fundora.

Someone could scrape the information from a betting site and do a quick data analysis.

Repeat: the most accurate way, for a ratio of underdogs who win is the simplest way. Just take total number of bouts were there was a favorite, i.e. an underdog. Now divide the number of underdogs by the number of those total bouts. That’s it. Of course other statistics can be considered but that’s an overall bottom line which can be done over a period of many years. You can assume that’s most exact. What? Have you fallen over recently?

On a Top Rank card, it's probably zero. I know they happen, though, and I always love them. Usually these fights are fixed with match-making but when it doesn't work out, it's hilarious. However, in the event of 50/50 fights, I'm very excited to see them. I just wish they happened more often. Boxing seems to avoid them in droves lately. Good post. Top Rank always seems verrrry selective about who they match their guys with. They like to find guys with padded records who’ve never fought in the U.S. before, like a Miguel Marriaga type from some years back. They do some good in-house fights, but it’s mostly trash otherwise. You’d have to pay me to watch Shakur

I'm not aware of anyone who's tracking THAT many fights to come up with any meaningful data, but if there is let me know where its at cuz I'd be curious to check it out myself. I suspect you'd have to research it & compile the info yourself. Which would obviously be quite the task. There would probably be a data base regarding betting somewhere, at a guess Id say its about 10-20% of non favorites that get up in competition, boxing is probably about the same, 10% in the big fights and 20% is the middle class fights.

There's a huge difference between a +120 underdog and a +1200 underdog. If you're using this to bet, you should have specific ranges of underdogs (+120 thru +190, etc.) and review percentages within each.

The simplest and most accurate way

Hopkins had a case for upsetting 5 different fighters in a row. Taylor, Tarver, Winky, Calzaghe, Pavlik. He was underdog vs all 5 of those fighters.

I think it fluctuates because there’s so many variables. You can compile data for 10 years and every year you will probably have different percentages, too different to give any definitive answer. Certain years I remember were like the year of the underdog, other years you’ll have most of the favorites winning. In recent years, I remember I think it was 2007, 2008, 2009, those years had a lot of underdogs winning iirc. Really big fights where the underdogs won, and even undercard fights. To name a few off the top of my head in those years: Cotto v Marg Hop v Pavlik Pac v DLH Mosley v Marg Donaire v Vic Linares v Salgado Williams v Quintana I Cintron v Angulo Pavlik v Taylor Ward v Kessler Maidana v Ortiz Vic v Mijares

I have a thread that people keep ducking where I list all of the high profile underdog upsets. It doesn't happen often: average two times a year. Can we give it up for the UNDERDOGS a minute? Shit man, that's a good thread. How have I never noticed it? Green K to you, sir.

I have been searching for the average amount of times that an underdog wins in boxing, but I can't find that number anywhere. Does anyone have a clue? Thanks! Don't know the answer to that my man, but I am a part of running the prediction league on here and I can tell you that compared to last year and 2017 it seems like we had an awful lot of upsets this year comparatively. We cover nearly all the major fights and have the betting odds on the OP of each thread so it should be fairly easy to check. Here's a list of all the PICK EM threads for 2018 and '19, you wanna trawl through 'em to get some data be my guest... :lol1: https://www.boxingscene.com/forums/search.php?searchid=7373000 If I had to guess it'd be somewhere in the 1/4, 1/5 range if you include those fights where the 'dog is in the sub 2/1 range... when you're talking about the kinda Ruiz - Joshua upsets maybe 1/20ish... as a (very) loose rule of thumb I'd say that given the random **** that happens in boxing, freak injuries and other weird **** a dog probably never has less than about a 5% of winning.

That's exactly what I have begun. Starting with the next upcoming events I'm going to be tracking underdog wins. As for myself, the last time I bet on 5 underdogs, 2 of them won. And on my first ever bet I won on a +1100 underdog.
