Instead, Graeme Gowland upheld Rob Mac Yamaha honours in ninth, but only after dropping as low as 15th from eighth on the grid. It was a tough race in all for the Yamaha team, with Chris Walker running 19th briefly before eventually claiming 14th, while Michael Rutter found himself outside the points in 16th.
By contrast, Kawasaki enjoyed a decent race, locking out positions tenth, 11th and 12th in the order of Tristan Palmer, Julien Da Costa and the penalised Laverty, while the hobbled Ian Lowry, Walker and tenth place starting Jon Kirkham completed the points.
Although well behind Mason on the track, Martin Jessopp claimed second in the Cup class on the Riders Racing Yamaha after a lengthy battle with Atsushi Watanabe. Peter Hickman was third.
