Tony Dorsett and Ron Springs each ran for a touchdown and Rafael Spetien kicked two field goals, including one of a career-longest 52 yards, in leading the Dallas Cowboys to a 19-13 victory over the Oakland Raiders today and into a tie for first place in the NFC East.

The Cowboys (11-3) clinched a playoff berth for the 14th time in the last 15 years with the victory, which was assured when cornerback Aaron Mitchell made an end zone interception of a pass by Oakland's Jim Plunkett with 1:44 remaining. Dallas plays Philadelphia, which lost to Atlanta Sunday, in the final game of the season Dec. 21.

The victory tied Dallas with the Eagles for the division lead with two games remaining. The Raiders (9-5) remained tied with San Diego for first in the AFC West.

Spring's touchdown, a two-yard run after Doug Cosbie recovered a fumble at the Dallas 46, and Septien's second field goal, a 34-yarder after a fumble recovery by Ed Jones, gave the Cowboys the points they needed.

Chris Bahr, who missed four of five field-goal attempts on Monday, failed on a field goal try from 41 yards but made good on kicks of 22 and 38 yards. Plunkett connected on a six-yard pass to Raymond Chester for the other Raider points.

The Cowboys dominated the first half when they piled up 177 yards in total offense for a 16-10 lead at the intermission.
