Bradford rider Dean Harrison added two further successes at the Southern 100 on Wednesday night to complete a hat-trick of wins at the event this week.
Kawasaki-mounted Harrison won the Senior race by 6.2 seconds from Manxman Dan Kneen, with Michael Dunlop a further 0.5 second behind in third.
Harrison set a lap record for the race at 113.473mph on his fourth circuit after overhauling early leader Kneen.
The 600cc event was red-flagged on the first lap following an incident.
The crash involved four riders and Honda rider and local hero Conor Cummins was airlifted to hospital where he was described as comfortable on Thursday morning.
Tom Parkes was also taken to hospital for treatment on his injuries and was later discharged.
The other riders involved, Ivan Lintin and James Cowton, escaped relatively unscathed.
When the race was re-run Harrison won on his Mar-Train Yamaha from runner-up Guy Martin and third-placed Kneen.
Lincolnshire rider Lintin won the Supertwins class by over nine seconds from Harrison, with Cowton third.
Ian Bell and Carl Bell won the first sidecar race from Dave Molyneux and Ben Binns, with Conrad Harrison and Jason Crowe third.
