Ostapenko claimed her second title by winning the final of the Korean Open in Seoul 6-7, 6-1, 6-4 in a little over two hours, over coming Brazil's Beatriz Haddad Maia in a hard-fought match.
Proof of Ostapenko's burgeoning star power came in the fact that the tournament recorded its first ever sell-out for the final with Ostapenko a clear favorite among the 9,000 spectators.
"I'm really happy to win my second title here and in my career. I enjoyed playing here, and to also see so many Latvian flags is amazing," she told the crowd in the post-match interview.
Ostapenko is currently ranked number 10 in the world, but her latest victory is likely to see that ranking improve further.
