KIA player Kim Doyoung is challenging the KBO league's youngest 40 home run record, but there has been an issue raised regarding the registration of players' birthdates, which are mixed between the Gregorian and lunar calendars. Former manager Lee Seung-yeop registered his birthday according to the lunar calendar, so his age based on the Gregorian calendar is different. This means Kim Doyoung's challenge for the youngest 40 home runs is likely to be unsuccessful. Choi Hyung-woo has also registered his birthday according to the lunar calendar, and there are growing calls within the KBO for a reexamination of record standards. Although the KBO has worked hard to correct past records, this issue goes beyond simple record errors and highlights the importance of potentially changing the age criteria for players.
