Air Force hands Boise State worst loss since joining Mountain West

AIR FORCE ACADEMY, Colo. — Safety Weston Steelhammer had three interceptions, and Air Force handed Boise State its worst loss since joining the Mountain West Conference in 2011, beating the Broncos 28-14 Saturday night behind seven takeaways.

Quarterback Kale Pearson rushed for a career-best 127 yards and a TD and threw a touchdown pass as the Falcons (3-1, 1-1) beat Boise State for the first time in three tries.

Steelhammer had two of the four interceptions thrown by Grant Hedrick before he was yanked late in the third quarter. Conference scoring leader Jay Ajayi fumbled twice.

The last time Air Force forced seven turnovers was in 1992 against Wyoming.

Boise State (3-2, 1-1) had lost just four league games — by a combined seven points — since joining the Mountain West. Its biggest loss before this was by three points — 34-31 on an overtime field goal against San Diego State last season.

Redshirt freshman Ryan Finley replaced Hedrick late in the third quarter after linebacker Jordan Pierce’s 56-yard interception return set up Will Conant’s short field goal that made it 20-0.

Pierce also blocked a field-goal attempt.

■ Colorado State 24, Boston College 21 — At Boston, Garrett Grayson threw a 12-yard touchdown pass to Charles Lovett on a fourth-down play with 1:02 left, lifting the Rams (3-1) past the Eagles (3-2).
