PHILADELPHIA — Army recovered two fumbles in the fourth quarter, Kelvin Hopkins Jr. had two rushing touchdowns and Army beat Navy 17-10 to win its third straight game in the series Saturday.

Army (10-2) retained the Commander-In-Chief Trophy – awarded to the team with the best record in games among the three service academies – after winning it for the first time in 22 years last season and snuffed a late Navy (3-10) rally to retain possession of the prize,

With Navy down 10-7, quarterback Zach Abey lost a fumble on fourth-and-12 deep in its territory. Hopkins scored on a 1-yard run to make it 17-7 and give Army the cushion it needed to win in front of 66,729 fans at Lincoln Financial Field.

Army hopped and waved hands in celebration during a replay timeout and got the cadets in the stands to bounce along. They had good reason to celebrate: Army regained its grip in a series that had gotten out of hand. Navy had a series-best 14-game winning streak from 2002-2015 and leads the series, 60-52-7.

Kell Walker ran 51 yards to the 10 on the fourth play from scrimmage and Hopkins dashed in for the TD on the next play for a 7-0 lead.
