Rhys Marchant and Jamie Sheldon both took 3-24 and Ryan Wiltshire claimed 2-28 as Mumbles dismissed Port Talbot for 120, before an unbeaten 75 from opener Tony Dowrick helped them race to their target in just 20.3 overs.
Victory gave league leaders Mumbles a two-point cushion at the top of the table, while second-placed Sketty Church thrashed Pontarddulais by eight wickets.

Six of Pontarddulais's batsmen were dismissed for ducks, while captain and No. 11 Ben Roberts was the only player to reach double figures with 12 not out.
Sketty Church's run-chase was a comfortable one, with Rob Jones (16no) and Jagadish Singh (20no) seeing them home in 7.4 overs.
Tata Steel's title hopes took a major hit as they were deducted 26 points for canceling their game against Ynysygerwn.

Gareth McNeil struck an unbeaten 88 and Liam Thomas hit 47 as Skewen posted 259-8 from 45 overs.
