Just be aware that there is a risk when betting on single players v team's of players. In a team, if one of the players gets a bad knock, they can replace him, not so in tennis. Be aware of rules in regard retirement due to injury. Some bookmakers refund your money, others like Ladbrokes don't.

RP, I would only apply this to singles tennis Open mens and womens matches.
And it's all done on Betfair.
All bets are on or off if retirement, so same same.

Tennis
If a player or pairing retires or is disqualified in any match, the player or pairing progressing to the next round (or winning the tournament in the case of a final) will be deemed the winner. However if less than one set has been completed at the time of the retirement or disqualification then all bets relating to that individual match will be void.

Maybe this might be a big factor why my back bets when arbing seem to win overall.

Gold Coast vs Western Bulldogs 3:20pm
Gold Coast Lay at $1.28 Back at $1.22 Potential loss $6.00
Western Bulldogs Lay at $4.80 Back at $5.30 Potential profit $5.00

That's not a good leverage in this case. :(

I did notice however, someone is backing the shorties to the tune of 25k and laying in play for the same. Odds were $1.28 back, $1.22 lay.
I'll tell you that's a mammoth risk based on some of the shorties going down convincingly this season. He's not going to get even a quarter of that matched before the bounce.

Lucky, he got matched this time straight away after the the bounce and only because two goals were kicked in fairly quick time, otherwise he'd be hanging on the edge.

Carlton vs Adelaide 4.40pm
Carlton Lay at $2.36 Back at $2.48 potential profit $1.20
Adelaide Lay at $1.74 Back at $1.67 potential loss 0.70c

These are just examples and odds didn't move greatly as I only went in late last night. Getting in early but still with decent liquidity is the key.

-$4.80 this time
+$4.20 for the thread.

Had a go on most of the 1st round French Open games last night - layed around 8 hours prior & backed 15 mins before the start for a small overall loss.

What surprised me was how little the odds had changed despite relatively large increases in amounts matched.
