Rain was the central concern around the June 20, 2026 Jamsil KBO Derby between the LG Twins and Doosan Bears, with the game scheduled at Jamsil Baseball Stadium while wet conditions made normal play a question. The available source material does not confirm a cancellation; it shows that the matchup was scheduled, rain was being monitored, and KBO decisions depend on on-site weather and field conditions.
Jamsil Derby Rain Cancellation Status

For fans planning around the Doosan-LG game, the key point is timing: the June 20 matchup was listed as the second game of the Jamsil derby series, following LG’s 3-2 win over Doosan on June 19. OSEN reported that the June 20 game was the season’s eighth meeting between the clubs at Jamsil Baseball Stadium, with attention focused on whether the game could proceed normally in the rain.1
The Doosan Bears official schedule also listed the June 20 game at 5:00 p.m. at Jamsil as pre-game, and showed the next game in the same series set for June 21 at 5:00 p.m. at Jamsil.2 That official schedule context is important because it confirms the planned game time, venue, and series placement, but it does not by itself establish that the June 20 game was canceled.
A day earlier, weather had already disrupted preparations around KBO games. EToday reported that the June 19 Jamsil Doosan-LG game was among KBO matchups facing possible rain cancellation, with sudden rain at Jamsil Baseball Stadium and ground crews placing a tarp over the field. The same report stated that, at 6:00 p.m., the rain probability at Jamsil was 50%.3

What Fans Should Check Before Going to Jamsil
The practical rule is simple: do not treat rain in the forecast as an automatic cancellation. EToday reported that KBO makes rain-cancellation decisions by comprehensively reviewing weather conditions at the ballpark and the condition of the field before the game.3 In other words, a forecast, a shower, or tarp installation can signal risk, but the final decision depends on the stadium situation.
For ticket holders and spectators, the most useful checks are the official team schedule, stadium status updates, and any KBO or club notices before leaving for Jamsil. The Doosan Bears schedule is particularly relevant because it lists the Jamsil series dates and game status.2 If a game remains listed as pre-game, fans should understand that the source material supports only a scheduled status, not a confirmed cancellation.
The June 20 game also mattered competitively. bntnews reported that LG stood in first place at 43 wins and 26 losses through 69 games, while Doosan was in fifth place. The same coverage noted that cancellations or interruptions caused by rain or showers could affect the standings picture and starting-pitcher plans.4
The previous day’s result added to that context. Mania Times reported that LG beat Doosan 3-2 on June 19, ending a two-game losing streak and maintaining first place. Song Chan-ui started as the leadoff right fielder and went 4-for-4 with 2 RBIs and 2 runs, including a go-ahead two-run home run in the fifth inning against Doosan starter Wes Benjamin.5
That means the June 20 Jamsil KBO Derby was not just a weather story. It was also the middle game of a meaningful rivalry series, with LG trying to hold first place and Doosan positioned in the top half of the standings race. Still, from a fan-service perspective, the weather decision was the first thing to verify before making the trip.
Rain Rules, Refunds, and Schedule Planning
bntnews covered rain cancellation and suspension criteria along with refund rules, but the provided source summary does not include detailed refund steps, ticket-platform procedures, or deadline language.4 Based on the available facts, readers should rely on the official ticket seller or club notice for the exact refund method once a cancellation is formally announced.
If the June 20 game is canceled, fans should also watch how the pitching schedule changes. bntnews specifically noted that rain cancellations or interruptions can influence starting-pitcher operations.4 That matters because derby-series planning often changes quickly after a postponed game, especially when teams are balancing rotation order and standings pressure.
