T1 continued its winning streak on the 1st by securing a comfortable victory in Game 1 against TLAW during the 4th round of the '2026 LoL Mid-Season Invitational (MSI)' Play-In stage, held at the Daejeon Convention Center Exhibition Hall 2.

T1 applied heavy pressure to the bottom lane and attempted a dive, securing a kill on CoreJJ's Rell, but Quid's Ryze quickly rotated down to take out Oner's Xin Zhao. Meanwhile, in the top lane, Doran's Ambessa solo-killed Morgan's Gnar, and T1 continued to target Gnar to gain a significant advantage.

Team Liquid also focused their efforts on the bottom lane, with Ryze picking up additional kills, while Faker's Taliyah gained a lead in the mid lane. Team Liquid managed to catch both Keria's Bard and Ambessa in the bottom lane, and after picking off Peyz's Ezreal, they won the ensuing teamfight, significantly closing the gold gap and securing the Rift Herald.

However, Team Liquid made a mistake in utilizing the Rift Herald, leading to Jarvan's premature death, which allowed T1 to gain a massive advantage in the mid lane. Team Liquid suffered a crushing defeat in the subsequent teamfight, widening the gap. Firmly in the driver's seat, T1 took the Baron, won the ensuing teamfight, and secured the objective. By the 26-minute mark, the global gold lead had ballooned to over 10,000, leading T1 to victory in Game 1.
