Born and raised in Cornwall, the young forward was always destined to take up rugby, following in the footsteps of his father Richard, the former Redruth and Cornwall prop.
However, Keast’s career really started to take off when he joined Truro College. Under the tutelage of the coaching staff at Exeter’s Academy base in the Duchy, he reached another level and that’s when the Chiefs moved to sign him.
Since then the Premiership outfit have worked hard on developing Keast as an upcoming prop within the modern-day game. Not only has he gone onto achieve international recognition with England at various age groups, but he has figured prominently for both Redruth and Plymouth Albion in the National Leagues.
Last season saw him feature for the Exeter Braves in the Aviva A League, but his big break came in November when he made his Chiefs debut in an Anglo-Welsh Cup clash away to Harlequins.
A week later, Keast was thrown in from the start in the same competition, putting in a highly impressive display as the Chiefs saw off Cardiff Blues 62-25 at Sandy Park.
