Svitolina wins Malaysian Open Second-seeded Elina Svitolina came back to beat Canada's Eugenie Bouchard 6-7 (5), 6-4, 7-5 in the rain interrupted Malaysian Open final Sunday. The match finished at midnight local time as rain interrupted play for well over three hours before the 21-year-old won out. Bouchard and Svitolina were on court for 2 hours 53 minutes between the three rain interruptions before the Ukrainian got a crucial break late in the decisive set to clinch the title. Svitolina lost the first set in a tight tie-breaker and Bouchard couldn't capitalize on early breaks in the second set. Despite breaking Svitolina's serve twice early in the second, Bouchard couldn't hold her serve in the eighth and 10th games to lose 6-4 before the final was stretched to midnight due to two long rain interruptions.
