Working off of Sebas' reasoning, Goku Black is more experienced with combat by far, so getting Sans to trip up will not be very difficult. And considering Black himself has Instant Transmission, to even out the teleportation, Sans doesn't have much of a mobility advantage.

Additionally, Sans can't take a hit from Black, while Black can most certainly take multiple hits from Sans. And unless he puts Black down quick, he'll adapt and surpass Sans easily. Sans' only real hopes of winning this is his hax, which is entirely possible, but Black will be far more willing to kill, and with all his ranged shit, trickery and such, I'd definitely say Goku Black has this in the bag.
