CINCINNATI (Reuters) - Serena Williams will try to fill one of the few holes in her resume this week but will need to up her game after labouring to a 4-6 6-2 6-2 win over Eugenie Bouchard at the Western and Southern Open on Wednesday.

In a career that has generated 54 singles titles, including 16 grand slams, Williams has won just about everything there is to win in her sport but Cincinnati, one of the WTA Tour's most prestigious tournaments, is not on that very long list.
