The quick thinking little scrumhalf has been fast-tracked into the Saracens squad after impressing the coaches while training with the club in 2011.
He had been planning a season with Cambridge, but ended up being drafted into the Sarries ranks and making his first team debut during the campaign.
Since arriving at the club in 2011 as a relative unknown from Cambridge RFC, Spencer quickly established himself as a name for the future with a series of composed displays for the club with experienced duo Neil de Kock and Richard Wigglesworth side-lined with injuries.
He impressed in pre-season with performances against Toulon and Bedford Blues to earn a full time contract and he continued to perform at the highest level in both the Premiership and Heineken Cup.
It was a whirlwind year for the young scrum half who made 21 appearances and also featured for England Saxons and was part of England’s Junior World Championship squad in 2012.
An England Saxons call-up duly followed and since Spencer has been a key player in Saracens' LV= Cup campaigns. This season he has broken into the senior squad and was included in Eddie Jones' England EPS squad for the first time.
In October 2017, the 25-year-old scrum-half signed a new deal to remain at Allianz Park until 2020.
During his 108 appearances for the Men in Black, he has helped Sarries to two Aviva Premiership titles, two European Rugby Champions Cup’s and an Anglo-Welsh Cup, with his last-gasp penalty in the 2015 Anglo-Welsh Cup final against Exeter Chiefs.
In June 2018 Spencer earned a call up into the England squad ahead of their tour to South Africa
As of the 2018/2019 Champions Cup, Spencer has had 21 European Cups appearances scoring 4 tries and 20 points.
