Korea defeated reigning Olympic champion Cuba to advance to the baseball semifinals of the Beijing Games as the top ranked country of the eight-nation preliminary.

At Wukesong Baseball Field in Beijing, Korea came from behind to beat Cuba 7 to 4. Korea scored five runs, all while having two outs in the bottom of the ninth inning, to secure the win.

Starting pitcher Song Seung-joon allowed just three in six innings.

The nation has now posted six straight wins in Olympic competition and will face the Netherlands on Wednesday. But Korea has secured a spot in the semifinals regardless of the result of the match against the European country.

The win marked Korea's first victory over Cuba since 1999.
