Gaithersburg 35,

Old Mill 13

Brian Porter finished nine yards shy of his own school record but still churned out plenty of yards to lead Gaithersburg past visiting Old Mill, 35-13, in a Maryland 4A quarterfinal last night.

The senior running back rushed for 311 yards -- nine yards shy of a school record he set last year against Damascus -- and scored four touchdowns before leaving the game with roughly six minutes remaining in the fourth quarter.

The seventh-ranked Trojans (9-1) will host No. 15 Sherwood in a semifinal next Friday at 7 p.m. Sherwood defeated Woodlawn in a quarterfinal last night.

"I would have loved to get the record, but I already hold it, so I would've just been breaking my own record," said Porter, who has rushed for more than 700 yards in the Trojans' past three games.

Simply stepping on the field in the playoffs was motivation for Porter.

Porter rushed for more than 1,000 yards last season but missed the playoffs after suffering a sprained ankle in the second to last game of the regular season.

"I was eager to play," Porter said. "After missing the playoffs last year, I was going to work real hard once we got in this year."

Porter's eagerness showed on the second play of the game when he broke through Old Mill's defensive line and out-sprinted everyone into the right corner of the end zone for a 88-yard touchdown run.

Gaithersburg failed to put Old Mill away in the first half -- the Trojans advanced inside Old Mill's 10-yard line twice without a touchdown. The Patriots evened the score at 7 when senior Brashaad Mayweather (136 yards) capped a 6 minute 28 second drive with a one-yard touchdown run with 1 minute 21 seconds left in the second quarter.

However, Gaithersburg took control in the third quarter. Senior Chris Malinowski recovered a fumble on the opening kickoff at Old Mill's 29-yard and Porter capped a nine-play drive -- in which he rushed the ball five times -- with a 12-yard touchdown run.

On the first play of Gaithersburg's next possession, Porter rushed down the middle of the field 67 yards to increase the lead to 21-13 with 4:20 left in third. He completed his day with a 19-yard run with 7:49 left in the fourth.

The Trojans limited the Patriots to 53 second-half rushing yards and forced six Old Mill turnovers. Old Mill is seeking its first postseason victory. The Patriots are 0-6 in the playoffs and have lost in the first round each of the past four years.
