Carew hockey team began the new season with a bang as James Mason bagged his first goal within 15 seconds of the start of the game, having 'walked' through the whole of the Swansea team from the push-back.
This set the standard for the first half, with goals coming from a fine move down the left wing, utilising the speed of Clemence, who crossed for Smith to put his first away.
Williams got on the score sheet with a fine run down the right, placing the ball past the Swansea 'keeper, and Smith got his second from a well-worked short corner routine.
Further goals should have resulted from the amount of possession the Rooks had, but the finishing touches simply were not there.
The Carew defence of Moseley, Bowles, Johnson and Ferguson was seldom troubled, with central defender Head marking the Swansea captain and centre forward out of the game and goalkeeper Thomas, who was only called on once, making a terrific save from the only short corner that Swansea had in the first half.
Leading 4-0 at half-time, Carew made some changes of personnel, while Swansea came out for the second half with far more sense of urgency, taking the game to the Rooks.
With Wheeler out with a head injury, captain Steve Kendrick and Mason ran and dominated the midfield, creating several scoring chances with moves through the middle and down the flanks, but it was Swansea who got the only goal of the half from a short corner strike.
Thomas made an important save from a penalty stroke to give the Rooks their first league win of the season.
