On the second lap, Dunlop pressed on and could now see Anstey ahead on the road, his lap of 127.525 mph only a fraction outside his own lap record. The lead was now close to 10 seconds with William still holding onto third although the rest of the leaderboard was shuffling somewhat with Martin up to fourth ahead of Donald, John McGuinness, Harrison, Gary Johnson on the MV Agusta and James Hillier.
As they left the solitary pit stop, Dunlop and Anstey were together and the pair of them had caught McGuinness, Donald and Hillier on the road giving the thousands of fans around the course a tremendous sight and the dice allowed the battle for fourth to go all the way to the line.
The top three positions were all but secure on the final lap, McGuinness giving William Dunlop a brief scare for third as he closed to within four and half seconds although the latter responded to take the final podium spot by over seven seconds.
It all meant Michael Dunlop took his fifth TT victory, equalling the total of his father Robert, with Anstey and William rounding out the podium, the first time the two siblings have shared a TT rostrum.
McGuinness took a strong fourth with Hillier having another excellent ride into fifth as he overhauled Martin on the final lap. Donald slipped back to seventh with Harrison, Dan Stewart and Dan Cooper rounding out the top ten.
Cooper’s 10th place made him the first privateer home ahead of Dan Kneen (11th) and Robert Wilson (13th) but Kneen has now taken over the lead in the overall TT Privateers Championship.
