Andrew Henke scored 21 points in Air Force's 57-36 win over TCU Wednesday.
The win gives Air Force (15-13, 7-8 Mountain West) sole possession of sixth place in the conference, while TCU (14-14, 6-9) drops to seventh.
Air Force led 24-17 at the break and took charge early in the second half despite the 3-point shooting of Keion Mitchem, who finished with 16 points to lead TCU scoring.
The Falcons lead by 17 at 49-32 in the second half and TCU could get no closer than 11 points as Air Force coasted to the win.
The win completes a season-series sweep for the Falcons, who won the earlier meeting 56-46 in Fort Worth.
Air Force finishes regular-season play on Saturday, hosting San Diego State.
