Stat Attack: Tuivasa-Sheck the NRL's try save king

While Roger Tuivasa Sheck might be known for his flair with ball in hand and electric feet, it's on the other side of the ball where he wants to truly stamp his mark on the game.

In the opening three weeks of the Telstra Premiership season, the Warriors' fullback has already come up with three contenders for try-saver of the year - most recently putting his body on the line to deny Canberra's Aidan Sezer in last Saturday's memorable 20-19 win at GIO Stadium.

In round one it was South Sydney Rabbitohs flyer Alex Johnston who was denied in the corner and in round two, Gold Coast Titans' winger Philip Sami had the ball dislodged on the goal line as he stretched out to score.

Warriors forward Jazz Tevaga revealed it was a personal goal for his captain in pre-season to become the top defensive fullback in the game - a goal he was well on his way to achieving.

"It's a massive boost for us, the way he (Tuivasa-Sheck) has been pulling those late tackles off. He truly does lead by example," Tevaga said.

"It's as good as scoring one (try) to be honest. It's a bit of a kick up the bum for the group. I know that it was a goal of his to be the number one defensive fullback in the game and he is certainly showing he can be just that."

The man himself was quick to deflect any praise, but said goal-line defence had been both a personal and team focus throughout the pre-season.

"That goal-line defence is something I have personally wanted to work on for a while, a few years ago I was embarrassed by some of my efforts, so it's an area I really want to step up in," Tuivasa Sheck said.

"There has been a massive attitude shift as a group on defence to be honest. Everyone has really brought into what we are trying to achieve here and all the boys are just keen to do their individual jobs really well, myself included."

Coach Stephen Kearney said some of his captain's efforts had been "inspirational", but in an ideal world wouldn't be necessary.

"If I'm honest, I don't actually want him making those tackles because it means the line has been broken," Kearney said. 

"Our focus this week, as a group, has been on defence, just tightening up on some areas I felt we weren't great in last week and just understanding what the Roosters bring to the table."
