PHILADELPHIA - Navy's decade of dominance over Army was 14 yards away from sinking.
Then the Black Knights botched a handoff with an overdue victory in sight and the Midshipmen pounced on the fumbled ball.
Keenan Reynolds helped Navy top Army for the 11th consecutive time, scoring the winning touchdown late in a 17-13 victory in the 113th rivalry game Saturday.
"It's hard to do," said Navy coach Ken Niumatalolo, a Radford?High School and University of Hawaii alumnus. "It's hard to beat anybody in a rivalry game, but to do it that long just speaks volumes about the guys in the white jerseys."
Navy (8-4) captured the Commander-in-Chief's Trophy awarded to the team with the best record in games among the three service academies.
"It means everything," Niumatalolo said. "That's our No. 1 goal, to get the Commander-in-Chief's Trophy. I'm just so happy for these guys."
Army (2-10) hasn't hoisted the CIC trophy since 1996.
The Black Knights were in this one until their final 70-yard drive. Army had driven to the 14 before quarterback Trent Steelman and fullback Larry Dixon fumbled on an exchange.
"We expected to win from the beginning to the end," said Army coach Rich Ellerson, a former UH player and assistant coach.
Reynolds scored the go-ahead touchdown for the Midshipmen on an 8-yard run with 4:41 remaining.
The game was played in front of 69,607 fans, including Vice President Joe Biden, at Lincoln Financial Field.
Navy's 27-21 win last season had been the tightest margin since the winning streak started. The Midshipmen now lead the series 57-49-7.
