  We propose a new search strategy for heavy top partners at the early stages
of the LHC run-II, based on lepton-jet final states. Our results show that
final states containing a boosted massive jet and a hard lepton, in addition to
a top quark and possibly a forward jet, offer a new window to both detecting
and measuring top partners of mass $\sim 2$ TeV. Our resulting signal
significance is comparable or superior to the same sign di-lepton channels for
top partner masses heavier than roughly 1 TeV. Unlike the di-lepton channel,
the selection criteria we propose are sensitive both to $5/3$ and $1/3$ charge
top partners and allow for full reconstruction of the resonance mass peak.
  Our search strategy utilizes a simplified $b$-tagging procedure and the
Template Overlap Method to tag the massive boosted objects and reject the
corresponding backgrounds. In addition, we propose a new, pileup insensitive
method, to tag forward jets which characterize our signal events.
  We consider full effects of pileup contamination at 50 interactions per bunch
crossing. We demonstrate that even in the most pessimistic pileup scenarios,
the significance we obtain is sufficient to claim a discovery over a wide range
of top partner parameters. While we focus on the minimal natural composite
Higgs model, the results of this paper can be easily translated into bounds on
any heavy partner with a $t\bar{t}Wj$ final state topology.
