The Swans maintained their 100% home record with victory over Coventry at the Liberty.
Darren Pratley nodded the home side in front midway through the first-half and they could have gone further in front during a dominant first 45 minutes.
The second goal did come right at the start of the second-half when Scott Sinclair capitalised on a defensive mistake to make it 2-0, but Ben Turner halved the deficit before the hour.
Coventry pressed for a leveller but the Swans held on to make it three wins out of three at home in the Championship.

Following on from the disappointment at Leeds both management and players were targeting maximum points from this week's games, starting with a win in the first midweek fixture against Coventry.
But after a stuttering start at Elland Road the Swans were quickest out of the blocks in this fixture as Stephen Dobbie, goalscorer at the weekend, went close with the first effort on the night just three minutes in.
The Scottish striker completed a sweeping move from the back which, with the aid of Scott Sinclair's pace, saw him fire wide of Keiren Westwood's goal.
Coventry fought back, however, with Dorus de Vries forced into saving from Lucas Jutkiewicz, but flashbacks from Saturday came flooding back for the Dutchman as striker Clive Platt went sliding into him in attempt to catch the loose ball.
Unfortunately for Dorus, Platt pulled his boot right across his face but emerged from the challenge unscathed. Platt, meanwhile, picked up the first yellow card of the night before turning provider on the quarter-hour mark, crossing for Jutkiewicz to bundle his attempt across goal and wide.
But barely two minutes had passed before two moments of trickery from Nathan Dyer - striding past Jordan Clarke - and then Joe Allen opening his body and turning Sammy Clingan and firing inches off target.
This game certainly had goals in it, compared to the last two Liberty meetings against the Sky Blues which ended goalless, and with 20 minutes on the clock the deadlock was in fact broken.
Sinclair's pace and persistence down the left forced Clarke into conceding a corner, Gower returned the delivery and Darren Pratley was ideally placed to direct his header into the bottom corner.
Every time the Swans went forward they looked dangerous, even the likes of Ashley Williams and Garry Monk were getting themselves into good positions as they made their way into the Coventry half.
But goalscorer Pratley came closest to doubling the lead on the half-hour when he sent another header goalwards, this time from Alan Tate's cross, but failed to hit the target.
He was also inces away as the half came to a close, Dyer pulling the ball back for him to curl across the face of Westwood and whisk past the upright.
Half-Time: Swans 1 Coventry 0
The home side burst out of the blocks at the start of the second-half and doubled their advantage with just over a minute played.
Coventry had just sent Martin Cranie on as a replacement and his first job was to send a weak back pass towards Westwood, Pratley got to it first and helped the ball onto the post but Scott Sinclair, who had acres of space, was able to help home the loose ball to send the Liberty faithful into raptures.
But the visitors weren't giving up hope of a comeback - former Everton frontman Lucas Jutkiewicz twice came close as he forced a save from de Vries and had a shot cleared off the line by Garry Monk, but with 11 minutes gone of the second-half they did halve the deficit when Ben Turner fired home as the defence failed to clear a corner.
Mark Gower saw a low drive immediately saved but Brendan Rodgers' side found themselves under increased pressure for large periods of time as Coventry went seeking a leveller, with the defence having to stay strong to keep out a rejuvenated Sky Blues.
The Swans were struggling to repeat their impressive form from the first 45 minutes in a bid to make the game safe, but Cedric van der Gun, on for Stephen Dobbie, did fire a shot straight at Westwood as the game drifted towards its end.
But Nathan Dyer could have sealed it two minutes from the end as he connected with a low cross from Tate, firing goalwards only to be denied by a fine Westwood save down to his left.
And the pacy widemen turned provider at the start of injury-time, of which there were four minutes, to find Scott Sinclair inside the area. He struck over but the Swans held on to continue their unbeaten home record despite a nervy second period.
