I guess it's a fold. Flop was fairly dry so someone could've been slowplaying a set, and I guess SB could complete PF w/ 58 if he was in a mood. The only hands you're beating that might play this way would be a super aggressive A5 or a flush draw and they have plenty of equity against you. (And are unlikely, and it's extremely unlikely that both of them have hands you beat.)
