No. 21 TCU Grounds Air Force 48-10

AIR FORCE ACADEMY, Colo. (AP) -- Jeff Ballard threw for 302 yards and two scores Saturday to help No. 21 TCU remain the only undefeated team in the Mountain West Conference with a 48-10 win over Air Force.<br> <br> Ballard went 20-for-28 to lift the Horned Frogs (7-1, 5-0) to their sixth straight victory and remain alone in first place in their first season in the Mountain West.<br> <br> Air Force (3-5, 2-4), which snapped a four-game losing streak last week, used its triple option to hold the ball for nearly 35 minutes, but mistakes hurt the Falcons. They had a punt blocked, committed 90 yards in penalties, missed two field goals and Shaun Carney threw an interception in the TCU end zone.<br> <br> TCU took the lead with a 74-yard drive on the game&#39;s opening possession, capped by a 1-yard touchdown by William Jackson. <br> <br> Trailing by 11, the Falcons pulled within 14-10 when Carney scored from 3 yards out midway through the second quarter. But Ballard answered by leading the Frogs on a 69-yard drive, capping it with a 15-yard touchdown pass to Brent Hecht, and the rout was on from there.<br> <br> TCU receiver Cory Rodgers caught six passes for 128 yards and a score.<br> <br> Carney finished 11-for-18 for 148 yards, but threw two interceptions, including one that Drew Coleman picked off in the end zone to end Air Force&#39;s opening drive.<br> <br> Tempers flared midway through the second quarter when TCU lost Coleman after a questionable downfield block by Air Force third-string wide receiver Victor Thompson. <br> <br> Thompson cut Coleman&#39;s lower legs in the back corner of the end zone as Air Force ran a dive up the middle at the 15-yard line. Thompson was flagged for an illegal block and as Coleman left the game with a right leg injury, TCU coach Gary Patterson was mad enough to yell at the officials and the Air Force bench.<br> <br> © 2005 The Associated Press.
