T1 closed out the series. On September 6, T1 defeated Dplus KIA 3-1 in Round 3 of the Lower Bracket at the 2026 LCK Playoffs, held at CHZZK LoL Park. Although falling behind early in Game 4, T1 turned the match around by winning consecutive late-game teamfights.

T1 drafted a Kalista and Renata Glasc combination in the bottom lane, aiming to apply pressure right from the laning phase. Things did not go according to plan. The first misstep came as they conceded laning kills to the duo of Smash (Shin Geum-jae) and Career (Oh Hyeong-seok). As Dplus KIA's bottom lane ramped up the pressure, T1 responded with a lane swap.

Leveraging their bottom lane priority, Dplus KIA took down the outer turret first. T1 sought to gain advantages during the lane swap as they had in previous games, but scoring proved difficult this time. In a skirmish in front of the Rift Herald, T1 succeeded in picking off Jax first, but immediately suffered losses from a swift counterattack. In subsequent engagements, Dplus KIA gradually pulled ahead, solidifying their control.

Dplus KIA attempted to bait T1 into fights around objectives. T1 refused to take the bait. Waiting for the right moment while buying scaling time for their carry lineup, the opportunity for a counteroffensive was created by the Kalista-Renata duo of Peyz (Kim Su-hwan) and Keria (Ryu Min-seok). Turning the tables on the pursuing enemies, they eliminated the carry line first, winning the teamfight decisively and securing Baron.

With their dive composition gaining momentum, T1 forced teamfights more aggressively. At the 27-minute mark in front of the Dragon pit, they baited out key enemy abilities before initiating a fight and coming out victorious. This battle expanded the gold lead to 7,000, and T1 pushed ahead to destroy the Nexus.

With this victory, T1 secured the #3 seed for the 2026 World Championship and will continue their playoff run at the KSPO DOME. Dplus KIA finished 4th overall in the LCK, locking in the #4 seed.
