The professional wrestlers of the Raijin stable are racking up their wins, and so is Matsutaro for that matter. But as to the beginner-level wrestlers, their nerves are getting the best of them; none of them are winning.
It's demoralizing for them 
to continuously lose.
Es ist schlecht für ihre Moral,
 wenn sie ständig verlieren.
Es desmoralizante perder continuamente.
Es desmoralizante perder continuamente.
O time ficou desmoralizado 
com as derrotas...
