SEATTLE — DeMarco Murray picked a good time to break off a history-matching run Sunday afternoon.

The Dallas running back’s 15-yard touchdown run with 3:16 remaining gave him 100 yards for the game and stood up as the game-winning score in the Cowboys’ 30-23 victory over the Seattle Seahawks.

Murray ended the game with 115 rushing yards on 29 carries to become the second running back in NFL history to open a season with six consecutive 100-yard games. He matched a feat accomplished by Jim Brown in 1958.

The Cowboys (5-1) earned their fifth consecutive victory despite setting up 17 Seattle points with a blocked punt returned for a touchdown, a muffed punt that led to a touchdown and a lost fumble that set up a field goal. Considering the venue and the opponent, this was Dallas’ most impressive win of the streak.

Dallas quarterback Tony Romo completed 21 of 32 passes for 250 yards and two touchdowns.

The Cowboys, who trailed 10-0 eight minutes into the game, rallied behind 162 team rushing yards, three Dan Bailey field goals and a defense that held Seattle to 206 yards of total offense.

Murray scored the go-ahead touchdown with 3:16 remaining for a 27-23 lead. Bailey added his third field goal with 1:05 remaining after the Seahawks failed on a fourth-down conversion from their own 23-yard line.

Bailey also connected from 56 yards out, tying the score 20-20 with 1:04 remaining in the third quarter.

Dallas punt returner Dwayne Harris mishandled a punt midway through the third quarter. Two plays later, Russell Wilson ran for a 9-yard touchdown that knotted the score 17-17.

Less than two minutes later, Romo had a low snap bounce off his knee for another turnover. That led to kicker Steven Hauschka’s second field goal of the game, which gave Seattle a 20-17 lead.

The Cowboys escaped their early hole and took a 17-10 halftime lead after tight end Jason Witten caught a 3-yard pass from Romo with 16 seconds left in the first half.

A field goal and a linebacker Mike Morgan’s return of a blocked punt gave the Seattle a 10-0 advantage.

Dallas pulled within 10-7 on a Romo touchdown pass to tight end Gavin Escobar with 2:34 left in the first quarter. The Cowboys tied the score when kicker Dan Bailey capped off a 15-play, 71-yard drive with a 42-yard field goal with 5:15 remaining in the first half.

Dallas went on another long drive — 80 yards over 10 plays — to end the half, culminating in Romo’s 3-yard pass to Witten on third-and-goal. The Cowboys scored on their final three drives of the first half, piling up 231 of their 234 first-half yards on the way.

Seattle finished with just 83 total yards over the opening 30 minutes. The Cowboys ended up with 401 total yards to the Seahawks’ 206.
