Starting at six for the Sunwolves in their clash with the Queensland Reds, the Gunnedah native who is known for his physicality made his presence felt early.

With his first involvement in the game, and the competition, he forced a knock-on. 

It set the tone for what was a brutal defensive effort from the Japanese side in the first half as they suffocated the Reds to lead 21-5 at the break.

Gunter was a pivotal figure in that. On another occasion the 21-year, who remains the youngest ever player to play in the Japanese Top League, helped drive a Reds player back five metres and almost into the in goal.

The Sunwolves were just as abrasive at the breakdown with Gunter and his backrow cohorts consistently earning praise during the commentary as they dominated their Queensland counterparts.

Unfortunately though he wasn't out there for much of the second half after being replaced by Amanaki Lelei Mafi five minutes in.

He was still the Sunwolves equal second top tackler for the game with 11 to go with four runs and one turnover.

It was a game of two halves with the Reds sparking to life in the second half to spoil Gunter's party and snatch a thrilling 34-31 win.

Hamish Stewart sealed their first win of the season with a clutch penalty with two minutes remaining after the Reds had stormed to a five point lead with three ties in 10 minutes.
