The KBO League (Korean: KBO 리그) is the highest level professional baseball league in South Korea, consisting of ten teams. The KBO League was founded with six franchises in 1982 and is the most popular sports league in South Korea. The Kia Tigers are the most successful team, having won 12 of the 44 championships.
In comparison with American Major League Baseball, ESPN reports that the KBO level of play "appears to be somewhere between Double-A and Triple-A, on average, though the best players are more likely to be MLB-quality than your typical Double-A league." Historically, the KBO is known for its vocal and exuberant fan base, as well as the widespread practice of bat flips (ppa-dun (Korean: 빠던), a portmanteau of the "first syllables of the words for 'bat' and 'throw'") by hitters after striking what they think will be a home run. In the KBO, the bat flipping tradition dates to the 1990s.
