Cargill, a product of the club’s youth set up, has been elevated permanently to the first-team ranks after impressing Howe during his time in the development squad.
The 19-year-old last season enjoyed fruitful loan spells in the Conference with Welling and at Torquay, winning his Football League debut for the Gulls in April.
Cargill, released by Southampton as a 12-year-old, has been sharing the defensive duties with Tommy Elphick and Steve Cook in pre-season and will again feature when Cherries visit Dorchester tomorrow (3pm).
And with Elliott Ward on the road to recovery having had knee surgery at the end of last season, Cargill could be in the frame for a place in the Cherries squad for their Championship opener at Huddersfield.
Howe, who rewarded Cargill with a two-and-a-half year contract in November, told the Daily Echo: “I said to Baily at the end of last season to come back as if he wanted to get into my first team. I don’t want people to aim to be in the development squad, I want all the young pros to try to be with us.
“There are limited spaces because of the number of bodies we have but, if someone proves they are good enough to be with us they will and Baily has proved that this pre-season. He has been excellent.
“The biggest compliment I can pay him so far is that he looks like he should be part of our squad. He hasn’t looked out of place in one training session.
“He is very composed on the ball, he is technically very good and he reads the game well for such a young player. I think he has a bright future ahead of him, providing he continues to keep the attitude he has shown.”
Asked whether another loan spell could be on the horizon for Cargill, Howe replied: “He is not going anywhere at the moment because our fit centre-halves are Steve Cook and Tommy Elphick and, as we speak, Baily is next in line.
“Hopefully, Elliott Ward will regain his fitness soon and we will have four very good centre-halves. In terms of loan periods for Baily, it is not high on my agenda to see him go out at this moment in time.”
Goalkeeper Lee Camp could be handed his first taste of match action against Dorchester after being given the all-clear to resume training earlier this week having missed the first two friendlies due to a minor thigh injury.
New signings Junior Stanislas and Callum Wilson could also feature after sitting out Monday’s victory at Eastleigh as a precaution.
Meanwhile, Cherries are unlikely to pursue their interest in striker Rakish Bingham who joined the club during the training camp in Austria and lined up in the friendly against FC Copenhagen.
