You can hear it around the 30 second mark. Sounds like Napoli calls Tanaka an “idiot” twice.

ESPN:

Mike Napoli hoped Masahiro Tanaka would make a mistake. The New York Yankees ace sure did — he twice shook off his catcher, then threw a pitch the Boston slugger could handle.

Napoli stung Tanaka by hitting a solo home run with two outs in the ninth inning, lifting Jon Lester and the Red Sox over the Yankees 2-1 on Saturday night.

What an idiot!” Napoli was heard exclaiming on Fox television microphones as he high-fived teammates in the dugout.

Napoli later said he didn’t mean any disrespect, adding he was “surprised” Tanaka didn’t throw his tremendous split-finger fastball.
