The Manly Sea Eagles are delighted to announce the retention of in-form second rower Frank Winterstein for a further two years.

Winterstein has extended for 2018 and 2019 following a highly successful transition from Rugby Sevens last year back to Rugby League.

Frank played three games at the end of last season and has turned out for the Sea Eagles in all 16 consecutive appearances on Manly's left edge this season to earn his upgrade and extension.

Manly Chief Operating Officer Neil Bare said the Sea Eagles were delighted to re-sign Winterstein.

"He is a pleasure to have at our club - a total professional both on and off the field.

"Frank is highly committed to our community programmes and will be used extensively in this area during the coming years. The manner in which he has transitioned back to Rugby League is a tribute to his professionalism." Bare said.

Winterstein, 30, made his debut in the NRL in 2008 with the Canterbury Bulldogs but then turned his attention to playing Rugby overseas after several seasons in the English Super League.

Sea Eagles Coach Trent Barrett said Winterstein had earned his new deal through consistently good performances this season.

"Frank took a punt with us and we took a punt with him. He is a pleasure to coach and his team mates love him in the side,’’ Barrett said.

"He turns up every week to play.”

Winterstein said he was enjoying life at the Sea Eagles.

“I am very grateful for the opportunity Trent gave me last year after three years out of the game,’’ Winterstein said.

“For me, it was about making the most of the opportunity and I have loved every moment of it.

“When the offer came to re-sign with the Sea Eagles for a further two years, I couldn’t turn it down.

“We have a great calibre of players at Manly and I wouldn’t find that anywhere else. There is something pretty special building here at the Sea Eagles and I’m glad to be a part of it.”
