Quarterback Dan Marino and split end Julius Dawkins combined for four touchdown passes and three school records to lead top-ranked and undefeated Pittsburgh to its 16th straight victory, a 48-0 win at home over Army yesterday.

The victory assured Pitt (9-0) of the No. 1 ranking for the third week in a row, the longest any team has been there this season.

Pitt's winning streak is also the longest in college football.

Pitt Coach Jackie Sherrill was cautious, however. "We are hoping we'll be there (No. 1) at the end of the year. Right now it doesn't make any difference," he said.

Marino completed 19 of 29 passes for 282 yards against an Army team that fell to 3-7.

Marino raised his season total to 158 completions, breaking the old Pitt record of 144 set by Ken Lucas in 1965.

The junior quarterback also boosted his season total to 2,099 passing yards, surpassing the old Panther record of 1,921 set by Lucas in 1966.

Marino's 28 touchdown passes add to the school record he set earlier this year. He already is Pitt's all-time career leader in passing yards and completions.

Dawkins, also a junior, raised his season total to 14 touchdown receptions, breaking the Pitt record of 10 set last season by Dwight Collins.

Dawkins finished the day with seven catches for 84 yards, including touchdown receptions of 13, 14, 6 and 10 yards.

It was the second shutout of the season for Pitt, whose defense is ranked No. 1 in the nation. Pitt held Army's top rusher, Gerald Walker, who was averaging 111 yards per game, to just 19 yards. Pitt also sacked Army's three quarterbacks three times for losses of 32 yards. Army managed just 11 first downs, compared to 34 for Pitt.

Army finished with 174 net offensive yards, 110 passing and 64 rushing. Pitt compiled 566 net yards, 276 passing and 290 rushing.

Pitt took a 14-0 lead in the game, scoring on its first two possessions.
