Russian Ekaterina Alexandrova registered a 7-6(4) 6-0 victory against top seed Jelena Ostapenko, who suffered a foot injury during the match, in the final of the Korea Open on Sunday to clinch her third WTA title.It was the second title of the season for the 27-year-old Alexandrova, who is ranked 24th in the world and was seeded second in the WTA 250 event in Seoul.Alexandrova was forced to play catch-up for most of the opening set against the aggressive play from the former French Open champion.But with superior court coverage and better control on unforced errors, the Russian rallied from a break down three times and also saved a set point to force a tiebreaker which she edged to take the opening set.Ostapenko, who won the Korea Open title and her maiden Grand Slam trophy at Roland Garros in 2017, suffered a right foot injury during the second set and needed a medical timeout to receive treatment on court.The Latvian could not muster much of a fight after the injury as Alexandrova breezed through the set and sealed the match with a backhand return winner, her 27th of the match.
