Samsung's contest with KT turns on the early pitching handover and the traffic created before the closing relievers. In Tosu, matching formations put the emphasis on escaping a marker and collecting the next ball. Both matches have useful attacking alternatives beyond the opening personnel.
Samsung can get its contact hitters aboard for Koo, Choi Hyeong-woo and Diaz, then make KT cover more outs before Park. Jang's planned short outing makes the relief entries central, and Bae has had two dates without a game appearance. Koo and Kang played the previous game with reported limitations; KT's hand, chest and ankle concerns remain conditional rather than confirmed exclusions.
I expect Samsung to challenge Allen's efficiency and keep an attacking response available into the bridge innings. That's why I'm siding with Samsung Lions to stay within a narrow margin.
Toyama's Tanimoto and Takenaka have already supplied inside receivers together, including against a matching formation. Kunitake's cross to Takahashi and the Matsuoka–Tsuboi option extend that supply after changes. Chong's absence predates the latest wins, while Sakamoto's return for Tosu is supported by two complete league matches.
Tosu should begin with width and pressure, with Toyama seeking central connections and arrivals from the opposite flank. The old cup result involved a different Toyama defensive group. That's why I'm siding with Toyama to avoid defeat.
