I want to refactor this method

streak.rb

  def streak
    return "-" if @played_games.empty?
    
    games=@played_games
    streak=0
    game=games.pop
    last_result=game.result_type(@team.id)    
    until game.nil? || game.result_type(@team.id)!=last_result do
      game=games.pop
      streak+=1
    end
    
    "#{last_result}#{streak}"
  end

After an afternoon of refactoring, I'm left with this ugly thing. Any thoughts? Basically, the functionality is to take the array of played_games (sorted) and determine a streak identifier from the last result (e.g. W3, L2, T1 etc).
