A 145m Grand Slam, a 23-Year Wait Ends: Kim Do-yeong's Jamsil Farewell Moment

The ball disappeared into deep left-centre; a 145m figure stayed on the record sheet. One swing sent KIA forward and left LG with a difficult last playoff memory at Jamsil.

In Game 3 of the KBO semi-playoffs at Jamsil on October 20, KIA led LG 3–0 in the second inning when Kim Do-yeong faced reliever Jon Kennedy with one out and the bases loaded. He drove a fastball out for a grand slam, extending the lead to 7–0. KIA went on to win 13–1.

This became more than a game highlight because it entered KBO history. The league's recorded distance, 145m, is the longest semi-playoff homer since such records began in 2000, and ties Tyron Woods's 2001 homer for the longest recorded across the postseason. LG's separate TrackMan estimate was 145.8m; these are different measurement systems.

A public r/baseball highlight discussion showed amazement at the distance and the stadium's approaching replacement. One commenter said a bar in Korea erupted when the hit happened. These are observations of individual comments, not a poll of Korean baseball fans.

Na Sung-bum also hit two home runs and Han Jun-su added another; all KIA starters scored and recorded hits. LG's season ended at Jamsil, due to be replaced. The attached Reddit embed is a public repost or discussion of the play, NOT an official KBO or broadcaster video post.

Verified figures: KBO official distance 145m, LG TrackMan distance 145.8m and 179.3km/h exit velocity. The second-inning pitcher was Jon Kennedy. The final was KIA 13, LG 1 and KIA completed a 3–0 series sweep. The Tigers advance to their first playoff round since 2003, with Game 1 against Samsung scheduled for October 25 in Daegu.

KIA next meet Samsung in Daegu on October 25. Remember the distinction between the semi-playoff distance record and the tied overall postseason record.
