Top polarization is an important probe of new physics that couples to the top sector, and which may be discovered at the 14 TeV LHC. Taking the example of the MSSM, we develop a detector level analysis methodology for extracting polarization information from hadronic tops using boosted jet substructure. We show that with 100 fb-1 of data, left and right 600 GeV stops can be distinguished to 4,5σ, and 800 GeV stops can be distinguished to 3σ.
