A day of firsts saw Swansea City score their first ever Premier League goal and secure their first victory since promotion last season in a 3-0 win over West Bromwich Albion on Saturday.
The honour of scoring the Swans' first goal of the campaign fell to Scott Sinclair, star of May's Championship play-off final victory over Reading, with further goals from Leroy Lita and Nathan Dyer completing the success.
Having started the match bottom of the table, Swansea finished the day in 13th place, with West Brom slipping four places into the relegation zone.
A sombre start to proceedings at the Liberty Stadium saw both sides respect a minute's silence in memory of the four miners who died at the nearby Gleision Colliery this week and the late father of Swansea coach Brendan Rodgers.
Swansea were dealt a blow shortly before kick-off when record signing Danny Graham was ruled out due to a back injury, with Lita taking his place up front.
Sinclair fluffed an early chance when the ball landed at his feet at the back post, but he made amends with a 14th-minute penalty after Paul Scharner had been penalised for going through Joe Allen from behind.
It was the first ever Premier League goal scored outside England and made Sinclair the first top-flight goalscorer for Swansea since Bob Latchford found the target in a 2-1 defeat at Manchester United in May 1983.
Neil Taylor almost gifted the visitors an equaliser in the 22nd minute when his errant back-pass inadvertently set Shane Long free on the edge of the Swansea box, but the Irishman blazed his shot over the crossbar.
Long's profligacy assumed new significance barely two minutes later, as Lita doubled the Swans' advantage with a close-range header from Sinclair's flick-on before tearing off his shirt in jubilant celebration.
A brilliant finger-tip save from Swansea goalkeeper Michel Vorm prevented Long pulling a goal back just after the half hour.
Dyer put the game to bed three minutes into the second half, cantering onto Lita's flick-on and drilling the ball between the legs of Ben Foster.
Vorm continued to thwart the Baggies, athletically denying Graham Dorrans, Peter Odemwingie and Long to preserve Swansea's defensive inviolability at home this season.
The only negative for Swansea was a troubling collision between Odemwingie and Taylor that saw the former booked and the latter stretchered off after being given oxygen on the pitch, prompting nine minutes of injury time.
