Kansas State allowed three unanswered runs, including the decisive one on a squeeze play in the seventh, to fall to No. 11 TCU, 3-2, on Thursday at Lupton Stadium.
The Wildcats (26-27, 8-14 Big 12) dropped their ninth one-run game of the season, including six in conference action, despite taking a 2-0 lead after the top of the fourth.
Two-out RBI singles by Tyler Wolfe and Brooks Zimmerman off TCU starting pitcher Brian Howard staked the Wildcats to their two-run advantage, but a two-out, two-run single by Dane Steinhagen in the fourth evened the score.
In the seventh, two batters after the Horned Frogs (36-14, 13-9 Big 12) chased K-State starting pitcher Parker Rigler from the game, Mason Hesse laid down a squeeze bunt off Nick Jones to allow the game-winning run to score.
