The Samsung Lions won the regular season and Korean series.

[2] On 19 July, the best players in the KBO participated in the Korean All-Star game at Pohang Baseball Stadium.

The franchises participating were divided into two regions: Eastern League (Samsung Lions, Doosan Bears, Lotte Giants, SK Wyverns) and Western League (Kia Tigers, Hanwha Eagles, LG Twins, Nexen Heroes, NC Dinos).

The titles 'Eastern' and 'Western' do not directly correspond to the geographical regions of the franchises involved, as both SK and Doosan, being from Incheon and Seoul respectively, are based in the Western region of Korea, despite representing the Eastern League.

The 2013 Korean All-Star Game was won by the Eastern League, 4–2.
