Based on the play of the hand...I think your 89 is worthless. The fact that you got two callers on your flop and turn bets are telling me your hand is no good. The check on the river really seals your fate, since they obviously didn't pick up the club flush draw on the turn.

I can't see them calling $5 on the turn just on overs, and there isn't an obvious straight or flush draw out on the flop based on the preflop action.

I'm thinking someone has pocket 9's or J's here, but I may be totally off base.

I wouldn't have called the preflop raise with that hand, especially from that position. They may be just letting you build the pot for them since you are betting out everytime, then got spooked by a combination of your aggressive betting + the 3rd club hitting on the river. Really hard to tell where you are here.

Be sure to post the results later, I am interested if YHIG or not.
