A Samoan International who broke through into top flight rugby league with the Bulldogs in 2008 before joining the Wakefield Wildcats in the English Super League in 2009.
However, Winterstein really began to make his mark playing for the Crusaders in the European Super League during 2010 and 2011 where he notched 49 matches in two seasons. His performances for the Crusaders led to him signing a two-year contract with Widnes Vikings from 2012 to 2013.
After his time with the Widnes Vikings came to an end, Winterstein crossed codes moving to Japan to play Rugby Union for Kintetsu Liners. This move lead to Frank making a push to win a spot in the Australian Rugby Seven’s team for the 2016 Rio Olympic Games.
Running into his former coach John Cartwright before Seven’s training one morning next to Manly’s Narrabeen facility, put himself on his former coach and the now Manly Assistant Coach’s radar as a potential boost to Manly’s depleted forwards stock.
After narrowly missing out on the Rio Games, Winterstein immediately signed with Manly and his second chance at an NRL career gained traction, appearing in Manly’s last 3 games of 2016.
The journey Frank has taken to get back to the NRL has been an arduous one at that, but in his own opinion is far better for it. Recently in an article with The Daily Telegraph “I came back a different player than I was in 2013,” “In the 15-man stuff I was an inside and outside centre. I did a lot of work on my long and short-range passing and a bit of kicking. The sevens program really boosted my endurance and fitness overall — it’s probably hands down the fittest I’ve ever been.”
Having started all of Manly’s 10 games in 2017 after winning the left edge second row spot, Winterstein is looking to hold down the position for the remainder of his NRL career stating “It’s the game I’ve played since I was a kid. I really want to prove myself as an NRL player while I’ve got the opportunity”.
