CHARLOTTESVILLE, Va. — Ryan Williams ran for 182 yards and four touchdowns and No. 14 Virginia Tech beat Virginia 42-13 Saturday in what was likely Al Groh's last game as Virginia's coach.

The Hokies (9-3, 6-2 Atlantic Coast Conference) won their sixth straight in the series and for the 10th time 11 meetings with the Cavaliers (3-9, 2-6). It was their eighth victory in nine games against Groh, and ended Virginia's worst season since it finished 2-9 in 1982.

Groh, who has a contract clause requiring that the school inform him by Nov. 30 if it plans to add a year, is expected to instead be fired. Virginia has had three losing seasons in the last four and its average attendance has fallen by nearly 14,000 in two years.

The Hokies, conversely, can reach 10 victories for the sixth year in a row if they win their bowl game. Only Texas and Southern California have also won 10 the last five years.

Williams had a lot to do with it on Saturday. He had scoring runs of 5, 20, 4 and 2 yards. He added a 51-yard burst in the fourth quarter that ended when he was stripped of the ball at the 10, but the ball squirted into the end zone and Hokies wide receiver Jarrett Boykin recovered for the touchdown, making it 35-13 with 10:21 to play.

The play also sent Cavaliers fans heading for the exits, turning the largest crowd of the season at Scott Stadium — 58,555 — into a vitual Hokies home game at its rival's stadium.

The touchdowns also allowed Williams to set a new ACC record for touchdowns by a freshman with 20. He started the day two behind T.A. McClendon of N.C. State, who did it in 2002.

Much of what the Hokies were able to do on offense, though, was set up by the passing game. Tyrod Taylor completed on 8 of 15 passes for 185 yards, with completions of 41, 36 and 38 yards in the first half, all against cornerback Ras-I Dowling, an All-ACC candidate.

Danny Coale did much of the damage, and finished with six catches for 135 yards.

The Hokies led 14-13 at halftime, but forced a turnover deep in Virginia territory to set up a 10-yard scoring drive in the third quarter, and essentially finished the home team off with a 62-yard march to Williams' final scoring run with 12:50 left in the game.

The turnover by Virginia came two plays after Chris Cook intercepted Taylor in the end zone, stopping a drive and giving Cavaliers fans short-lived hope for a comeback.

On the Cavaliers second play, Jameel Sewell ran an option to the left, attempted to flip the ball to Mikell Simpson. But his toss was behind Simpson, who couldn't catch it. Instead, Hokies safety Kam Chancellor scooped up the losse ball and returned it to the 10.

Sewell finished with a career-best 103 rushing yards, but that was the bulk of Virginia's 118th-ranked offense as they were outgained 489-292 and turned the ball over twice.

The Cavaliers got the opening kickoff and drove straight down the field almost exclusively by running the ball. Sewell had runs of 28 and 15 yards, the last for a TD.

The Hokies answered, driving 84 yards in seven plays. Taylor hit Coale for 41 yards early in the drive, and then converted a third-and-17 by hitting Coale again, for 36 yards.

Williams finished the tying drive with a 5-yard run, and gave the Hokies a 14-10 lead in the second quarter, taking an option pitch from Taylor and bolting 20 yards.

The Cavaliers pulled to 14-13 on Robert Randolph's second field goal of the first half, a 41-yarder with 39 seconds left. The kicks made him 17 for 19 on field-goal attempts this year.
