Jil Teichmann’s remarkable run in Cincinnati was ended by a clinical Ashleigh Barty 6-3 6-1 in the women’s singles final.
But the world number one took her fifth tournament win of the season in an hour and 13 minutes.
Barty broke for 5-3 and served out for the first set, while the Swiss lost all four service games in the second set.
In the men’s singles final, Olympic gold medallist Alexander Zverev needed just an hour to take the 17th title of his career at the Western and Southern Open.
The German drew first blood in the final against Andrey Rublev, breaking the Russian’s service for a 1-0 and 3-0 lead in the first set.
Zverev, who battled to a three-set win over Stefanos Tsitsipas in the semis, polished off the first set inside 28 minutes, serving out for 6-2.
The second set started in a similar vein to the first, Zverev breaking Rublev’s serve in the first game, and the German broke again for a 4-1 lead.
Rublev got a break back for 5-3 in the second, but lost his serve for the third time in the set as he went down 6-3.
Meanwhile, Andy Murray is through to the next round of the Winston-Salem Open after defeating lucky loser Noah Rubin 6-2 6-0.

American Rubin stepped in but the Brit was too strong and will now face Frances Tiafoe in the next round.
There were also wins for Gilles Simon, Marcos Giron, Mikael Ymer, Soonwoo Kwon and Thiago Monteiro.
