Home fans at Daegu Samsung Lions Park, which drew a full house of 24,000 spectators for two consecutive days, fell into shock and silence.
Doosan Bears defeated Samsung Lions 8-7 in an away game in Daegu on the 30th, hitting another walk-off grand slam to come from behind. Samsung failed to hold its leads of six and five runs over the two days, suffering painful back-to-back losses.
Doosan, which had taken a comeback victory the previous day (29th) with six runs including Kang Seung-ho's walk-off grand slam in the bottom of the ninth, again overturned the game by scoring six runs in the bottom of the sixth while trailing 1-6.

With a walk by leading batter Yang Eui-ji, a double to left-center by Kang Seung-ho, and a hit-by-pitch by Yoon Jun-ho, Doosan created a bases-loaded opportunity with no outs. Substitute batter Im Jong-seong then drove in a run with a single to left field. Although Samsung replaced starter Oracle with Baek Jeong-hyun, Doosan's Park Chan-ho drew a bases-loaded walk in the continued bases-loaded situation to close the gap to 3-6.
Jung Soobin, who had hit a go-ahead solo home run in the bottom of the ninth the previous day, stepped up to the plate. He connected with Baek Jeong-hyun's first pitch, a 138 km/h fastball, launching a 120-meter fly ball to deep left-center field. This was Jung Soobin's second career walk-off grand slam, his first since August 19, 2014, against Incheon SK. Doosan added another run in the top of the eighth on Kim Min-seok's RBI single.
On the mound, Lee Byung-hun, Kim Jeong-woo, and Lee Young-ha pitched in succession from the bottom of the sixth to secure the victory. Lee Young-ha allowed one run in the bottom of the ninth over one inning but recorded his second consecutive save and the sixth of the season.

For much of the game today, Samsung controlled the pace. Diaz, who had been batting seventh due to recent offensive struggles, hit a go-ahead solo home run off starter Choi Seung-yong in the bottom of the third while trailing 0-1, followed by a deep left-center field home run in the bottom of the fourth while leading 4-1. This was his first home run in six games (his eighth of the season) and his third career back-to-back home run series.
Park Seung-gyu, who entered as a defensive replacement for left fielder Koo Ja-wook in the top of the fourth, hit his seventh home run of the season, a solo shot over the left-field fence, off reliever Yang Jae-hoon in the bottom of the fifth. This set a new single-season personal record (previously six in 2025). Samsung narrowed the gap to one run in the bottom of the ninth on Kim Seong-yoon's RBI single, but Choi Hyung-woo struck out with two outs and runners on second and third.
