Playing only the first three quarters, Manning completed 15 of 27 passes for 271 yards. He suffered one interception, but the turnover did little to slow the Grizzlies, who led 27-14 at halftime and put the game away with 19 straight points late in the third quarter.
Logan improved to 3-1 this season, while Judge slipped to 2-2.
Asked about the play of Manning, a rangy senior, Logan coach Mike Favero said, "It's a team deal, you know? He played well, but our receivers also played well and our O-line blocked well. Football is the ultimate team sport and it requires everybody doing the thing right. If they do, then you've got a chance to be successful."
In a game played at Juan Diego because of problems with Judge's home field, Logan started quickly.
On its first possession, the Grizzlies marched 65 yards in only six plays and grabbed a 7-0 lead when Manning hit Josh Thompson with an 11-yard touchdown. Manning went 4-for-4 for 34 yards on the drive.
After a Judge punt, the Grizzlies got a break when a penalty on Thompson's missed 37-yard field goal gave him another chance, which he converted from 32 yards out to make it 10-0.
The Bulldogs tried to stay close on Mitch Wood's 72-yard touchdown run up the middle, but Logan quickly countered when Manning hit Thompson on a 65-yard catch-and-run that restored Logan's 10-point lead.
Late in the first quarter, Judge started playing give-away.
Quarterback Chris Pell fumbled - the first of three straight possessions to end with a turnover - Thompson followed with another 32-yard field goal.
Manning ended up throwing for 225 yards in the first half, but Logan managed only a 27-14 lead.
Judge was still in the game midway through the third quarter when Pell threw another interception, setting up Manning's one-yard touchdown run. The Grizzlies ended up scoring 19 points in a six-minute span to bury the Bulldogs who, with standout linebacker Zack McKown again hobbling on an injured ankle, have now allowed 93 points in their last two games.
