DUBAI: Angelique Kerber dominated Monica Puig 6-2, 6-3 in barely an hour at the Dubai Tennis Championships on Wednesday to move a step closer to returning to the number one ranking.
The top-seeded German who held the top WTA spot in 2016 before Serena Williams took it back in September, could regain the number one ranking were she to win the Gulf event on Saturday.
Kerber's victory also provided revenge against Puerto Rican Puig, who beat the 29-year-old for the Rio Olympic gold medal in August.
Kerber improved to 3-1 in the series with her comfortable win over the number 42 seed at the Aviation club.

"I was just thinking about my game, about my rhythm, and not thinking too much about my opponent tonight."
The German will next line up against Ana Konjuh, who eliminated eighth seed Elena Vesnina 3-6, 6-4, 7-6 (7/4).
