Seeking an unprecedented seveth victory at the Macau Grand Prix, Michael Rutter topped Thursday's practice times.
He was nearly a second quicker around the street circuit than defending Champion Steve Platter in second with 13 time T.T. winner John McGuinness third quickest.
A win for Rutter in Saturday's race would move him ahead of Ron Haslam on the all-time list.
Ramsey's Conor Cummins, making his debut at the event, was 15th with Castletown rider Chris Palmer just behind in 16th.
