I was base umpire. Before I could even say anything my partner said he did get obstructed and awarded him the base. I let it go and didn't argue it, mainly because while I "believe" he has to complete the trip to 2nd in order to get an obstruction call, I'm not completely sure. And I don't have my books on me at the moment.

Both you and your partner were wrong. He does NOT have to attempt to get to 2nd to be awarded 2nd. However, it's most likely that your partner erred in awarding 2nd - as it sounds like there's no chance the runner would have achieved 2nd base. The OBS protects him between the bases where he was when obstructed - sounds like between home and 1st if that's where F1 was. So he was safe at first even if thrown out. But 2nd doesn't seem likely here.
