Blaydon are still without a win on their travels and not for the first time this season gained no reward for a lot of effort and for most of the game a more than equal share of possession.
Particularly in the first half they more than held their own yet found themselves 9 points adrift, Matt Jones the Coventry fly-half successful with 3 penalty attempts.
The home side made better use of the conditions in the second period and racked up 12 points whilst Blaydon were a man down. Repeated scrummage offences had led to a yellow card being brandished but ironically to Robbie Morris a replacement prop who had been on the field for less than a minute.
The opening try for Coventry came from some good build-up which they spun wide for Uruguayan full-back Gaston Mieres, on debut after appearing in all 4 games for his Country in the recent World Cup, to finish off.
Winger Dom Lespierre then took advantage of loose play to run in two more scores as Blaydon began to wilt. Jones converted all 3 efforts and added a penalty to take his personal tally to 18 points.
In the closing stages Devlin Hope, a replacement forward touched down from a maul to earn Coventry a try scoring bonus point.
On a day of few pluses for the visitors fly-half Brett Connon had a fine game as did young scrum-half Ruaridh Dawson who only just arrived back in time from the Newcastle Falcons Friday night trip to Brives.
