Tom Trbojevic returned to the Manly side against Wests Tigers but was upstaged by younger brother Ben who grabbed a brace in the 36-22 victory.
The Sea Eagles are priced at 12/1 to win the grand final this season and currently sit seventh on the ladder after picking up their fifth win from nine games.
Star fullback Tom Trbojevic was back in the side and for the first time ever lined up alongside brothers Ben and Jake in the same Sea Eagles side.
And it was the youngest of the three, Ben, that ended up writing the headlines with a try either side of the break.
"It was a game Benny will remember for a long time," Manly coach Des Hasler told reporters after the game. "It was a late change for him moving from centre into the back row.
"He'll get an enormous amount of confidence out of today. I'm very happy and proud of him. It was great to see Tom get through today and he'll be much better for today's run."
The Tigers were not helped by losing prop Thomas Mikaele and winger Ken Maumalo to concussions in the first half. Stefano Utoikamanu also had a spell in the sin bin and they paid the price.
"We were very solid for a long period of time, we just got opened up," Tigers coach Michael Maguire said. "We needed to finish our good ball and our field position and all of sudden the scoreboard starts to tick and you do things outside of what you want to do.
"Going down to 12 men, they score two tries and you play outside of what you have been practising. We're capable in our attack but we've just got to give ourselves the opportunity to do that."
