Sportsmaster, Deathstroke Vs Owlman ( Earth 3) and Batman

They are in Crime Alley in Gotham. Owlman and Batman were fighting but they seem to have been met by a team of DS and SM. They are in character and they have standard gear. No prep, just battle.

No one? Okay

Deathstroke could beat anyone there but I think Sportsmaster a handicap so it could really go either way,I'm going to say DS and SM 6/10.

@generator2000: wait is this new 52 or pre 52?

@darkbeam: If I make a DC board, it's pre 52.

@generator2000:

all right still the same DS and SM 6/10.

Deathstroke and Owlman could last for a while, and then batman and Owlman double team deathstroke after batman beats sportsmaster. The same could happen if sportsmaster holds of batman while slade kills Owlman, and they jump Bruce.
