Naruto probably starts in base, considering however that a) he only needs a few seconds for Sage mode, b) he has Sasuke near him, c) can summon frogs including Bunta and might use a few clones for distraction although he must be careful to not let that conflict with getting sage mode, he can gain Sage mode IMO in this scenario.
I see Sasuke and Naruto winning actually Sage Naruto with Bunta, and Susano, Amaterasu and genereal MS abilities Sasuke is too much for these ten. Even Sasuke alone would had a chance for victory or atleast to do significant damage. Considering Sasuke can use Susano and fire arrows at range, or combine it with Amaterasu, or attack with Amaterasu while in Susanoo, the rookies would certainly have a tough fight ahead of them...
