Flying Kiwi Bruce Anstey had the upper hand during final Supersport practice for the MCE Ulster Grand Prix at Dundrod.
Anstey claimed pole by 1.7 seconds on the Valvoline Padgetts Honda from Ian Hutchinson, who is back on the Came BPT Yamaha on which he has won the last four Supersport races at the Isle of Man TT.
Anstey topped the charts with a lap of 125.944mph with Hutchinson managing 124.901mph until the session was halted following an incident at Flow Bog as spots of rain began to fall. The rider involved escaped serious injury.
Conor Cummins finished third quickest on the Valvoline Padgetts Honda at 124.530mph with Bradford's Dean Harrison fourth on the Silicone Engineering Kawasaki. William Dunlop on the IC Racing Yamaha and Peter Hickman (Trooper Beer Kawasaki) completed the top six.
Michael Dunlop, who topped the Superbike and Superstock sessions, qualified seventh on his MD Racing Yamaha followed by Dan Kneen on the Mar-Train Yamaha. Paul Jordan and Dan Cooper were the top ten.
Gary Johnson's lap of 121.701mph would have been good enough for ninth place on the grid, but the Lincolnshire rider only managed three laps in all on the East Coast/Burdens Triumph and is listed as a non-qualifier.
Johnson missed Wednesday's practice after being drafted into Phil Reed's team as a late replacement for Lee Johnston, who has been ruled out with a broken collarbone after a crash during practice on Wednesday.
