Four times on Sunday Johnson-Fisher stormed his way to through a hapless defensive line, pummelling opposing centres from the Bishop Wordsworth's School.
"One fellow was quite fast and we didn't close him down as quickly as we wanted to" the director of rugby at Bishop Wordsworth Terry Gilmour told the Rutland Times.
For Oakham's upcoming opposition the worst news is that Johnson-Fisher is still coming to grips with the game after training as a sprinter.
He bagged the new National Schools Championship 100 metres record in Birmingham last summer
"Tyrese has the ability to score from anywhere, he is a very powerful runner," said Oakham School's director of rugby Ian Smith.
"He's still learning the game but he gets better every time we see him play."
