Barbora Krejcikova advances in rain-soaked Seoul

Barbora Krejcikova of the Czech Republic cruised to a 6-1, 6-2 win against Russian qualifier Tatiana Prozorova during a rain-filled Tuesday session at the Korea Open in Seoul.

After a two-hour weather delay, the two-time major champion won 80 percent of the points on her first serve and saved both break points she faced in the 76-minute victory.

Krejcikova's second-round opponent will be the winner between No. 8 seed Emma Raducanu of Great Britain and Romania's Jaqueline Cristian, whose clash was one of five first-round matches postponed to Wednesday.

In Tuesday's only other action, No. 5 seed Diana Shnaider of Russia is tied 2-6, 6-2 through two sets against American qualifier Caty McNally.
