New to NL Tourns. is this weak PF? -resuluts in white-

[flyangler]

I have only played in a few NL Tournaments but this hand made me scratch my head.
This was very early in a STT and I don't know if I made a mistake, please take a look and tell me if I was too weak preflop or was this just a suckout.
