Despite a promising and competitive start to proceedings, the first set raced away from Raducanu when Swiatek turned up her power game to register two breaks and a 5-1 lead, serving the set out for a comprehensive success in the end.
Swiatek broke Raducanu early into the second set, but the Briton missed the chance to hit straight back by failing to take three break-point chances after a couple of Swiatek double faults.
Instead, Swiatek registered a nervy hold after the longest game in the match, and kicked on from there to break Raducanu once more and serve out the match.
