A strong second half, followed by a less impressive second, has seen the Sharks get the better of the Roosters on Good Friday in their round four Jersey Flegg match at PointsBet Stadium.
The Sharks were dominant in the first period, racing out to a 20-0 lead and despite letting their opponents back into the contest after the break, were still too good in registering a 20-10 win.
The victory was the third in succession and third in four starts so far in 2021 for the under-21 Sharks squad.
The Sharks were on the board early when centre Kyle Pickering finished off a slick backline movement to slide over out wide and when half Angus Ernst sliced through soon after, with the Pickering conversion of the second try, it was 10-0 to the home team.
Ernst was then in the game again, putting through a well-weighted grubber for James Coyne to score and despite missing the kick at goal the Sharks were well in control at 14-0 after he first 25 minutes of the contest.
More was to come for the Cronulla side when hooker Isaac Longmuir, one of his team's best on the day, dived over under the uprights just before the break and it was 20-0 Sharks as the teams headed to half time.
The Roosters gave themselves some hope with a long range intercept try early in the second period, than backed that four pointer up with another try 10 minutes from full-time, however the Sharks would hang on despite being somewhat disappointing with their handling and ball control late in the game.
In addition to Longmuir and Ernst, the number seven kicking intelligently and enjoying a good afternoon running the football, the Sharks were well served by Jack Martin and Tyler Slade in the forwards, with Franklin Pele a handful for the Roosters defence.
The Jersey Flegg Sharks have a bye in round five, with their next match against the Victorian Thunderbolts in Melbourne in round six.
