ANNAPOLIS, Md. -- Halfway to their first 10-win season in 23 years, Southern Miss made Navy pay for its early inability to score, then poured it on for its fourth straight victory.
With a bye week ahead before a stretch of six Conference USA games, the Golden Eagles will have plenty of time to savor a most satisfying triumph.
Austin Davis passed for 283 yards and three touchdowns, and Southern Miss beat Navy 63-35 on Saturday.
"Since I've been there, I think this is as good as we've executed from the start to the finish," said Davis, who engineered nine touchdown drives in 13 attempts. "I thought we didn't let up in the second half. We played just as well in the second half as we did in the first."
Though Southern Miss couldn't completely corral Navy's vaunted running attack, the Golden Eagles didn't let the Midshipmen grind out so much yardage that they were playing from behind early on.
"I knew they could score," Southern Miss coach Larry Fedora said. "But I thought we could make them snap it and score and eat some clock. They were getting too many big plays and when they are doing that offensively, you have to answer."
Navy (2-3) rallied for 28-second half points but lost a third consecutive game for the first time in four seasons under coach Ken Niumatalolo, surrendering a season high in points.
"It's been a long time since we got our butts whipped like that," Niumatalolo said. "And that starts with me. It was a thorough beating."
The Midshipmen played without fullback Alexander Teich, their leading rusher, who was held out for disciplinary reasons.
"Any time you lose one of your star players, it affects the team," Navy quarterback Kriss Proctor said. "But this was a team loss, not a one-player loss."
Navy's Delvin Diggs ran for two touchdowns, and Proctor added 123 rushing yards.
It was the most points allowed by Navy since a 65-19 home loss to N.C. State on Sept. 7, 2002. Southern Miss, meanwhile, topped 50 points for the second time in four games and is averaging 48 points a game during their winning streak.
The Midshipmen amassed 416 rushing yards, but paid for squandering early scoring opportunities.
Navy drove to the Golden Eagles' 7-yard line on the game's opening drive, but Southern Mississippi's Khyri Thornton blocked Jon Teague's 29-yard field goal try and Marquese Wheaton scooped up the loose ball, returning it 79 yards for a touchdown.
The Midshipmen moved to the Southern Miss 1 on the ensuing drive, but failed on three tries to punch the ball across for a score. Tim Green stuffed Proctor's fourth-down keeper attempt.
"That was basically just a bend-but-don't-break attitude that we had given up some big plays on those first two drives," Southern Miss linebacker Ronnie Thornton said. "We decided to buckle down down there in the deep end."
The Southern Miss offense didn't touch the ball until 3:59 remained in the opening quarter, and Davis directed a 99-yard scoring drive capped by Hester's 3-yard scamper up the middle for a 14-0 lead.
Lampley's 4-yard scoring run put the Golden Eagles up 21-0 with 11:18 remaining in the first half.
Davis found Ryan Hanks uncovered in the end zone for a 5-yard scoring pass and a 28-8 lead 7:32 before halftime.
Davis finished the first half 13 for 14 for 191 yards.
Proctor needed only 57 seconds to move Navy 74 yards early in the second half, leading Brandon Turner over the middle for a 43-yard touchdown pass to trim the deficit to 35-14.
But Davis threw his third scoring pass of the afternoon, a 10-yard strike to Kelvin Bolden in the back of the end zone, for a 42-14 Southern Miss lead.
Diggs scored on a 1-yard run, but Southern Miss used a trick play -- an 18-yard pass from Quentin Pierce to Collin Jarbo -- to increase its lead to 49-21. Proctor then threw a 27-yard TD to Gee Gee Green with 40 seconds left in the third quarter.
Lampley's second touchdown run made it 56-28 early in the final quarter. Diggs then scored from 7 yards out for Navy.
Davis' 1-yard run with 5:18 left concluded the scoring.
