Favourites (M) Slammed

Wimbledon 2017 ended a run of six Men's Grand Slam tournaments where backing the favourite in every game was a profitable strategy.

Here are the results for backing Grand Slam favourites this year at Pinnacle's prices:

and for the 2016 season:

Conventional wisdom for tennis betting is that in line with the favourite-longshot bias, backing the favourite will result in you losing your money slower than you would by backing the outsider. 

Backing the outsider would have been profitable in Australia this year, simply because of two long-priced winners - Istomin beat Djokovic at a best priced 41.0 and Zverev beat Murray at a top price of 28.0.  

In the eleven Grand Slams (Men) since 2015, an underdog backer at Pinnacle's prices would have lost 181.22 points, 16.47 per tournament, while a favourite backer would be up 14.24 points, 1.29 per tournament.

If you believe in unicorns, Santa Claus, angels or gods, then by backing at the best priced books, your losses would be reduced to 108.02 points on underdogs, and profits boosted to 35.24 points on the favourites.
