ARLINGTON, Texas — Dak Prescott threw two touchdown passes to Amari Cooper before running for another score, and the Dallas Cowboys pulled out of a first-half funk as huge favorites in a 31-6 victory over the Miami Dolphins on Sunday.

  • Josh Rosen made his first start for the Miami Dolphins, throwing for 200 yards with no touchdowns and no interceptions
  • The Dallas Cowboys improved to 2-1 on the season
  • Miami is 0-3 for the first time since 2011

One of Prescott’s TD tosses to Cooper came before halftime, but the Dolphins had a great chance to lead at the break as 22-point underdogs when Kenyan Drake fumbled on first down from the Dallas 7-yard line in the final minute of the second quarter. DeMarcus Lawrence recovered to preserve a 10-6 lead.

Josh Rosen was 18 of 29 for 200 yards without a touchdown or interception in his first start for Miami, which went with him over Ryan Fitzpatrick after getting outscored 102-10. No team since 1961 had a worse point differential through two games.

The rebuilding Dolphins are 0-3 for the first time since losing their first seven in 2011. They have been outscored 133-16, the largest point differential through three games in the league history since 1950.

Prescott fueled the first Dallas team in 41 years to win its first two games while rolling up at least 400 yards and at least 30 points each time. And while the Cowboys reached 3-0 for the first time since 2008, it took them awhile to find that offensive form.

The second touchdown to Cooper was a 19-yarder that capped a 75-yard drive to open the second half, and came after a 74-yard TD toss to Randall Cobb was nullified by offsetting penalties.

Prescott ran 8 yards to cap the second straight TD drive to open the second half, pulling him within one of Roger Staubach’s career club record of 20 rushing touchdowns in just his fourth season. Prescott was 19 of 32 for 246 yards with an interception, and Cooper had six catches for 88 yards.

Ezekiel Elliott had his second straight 100-yard game after missing the entire preseason holding out for the $90 million extension he signed the day of the first full workout before the regular season.

Rookie Tony Pollard, who became the top option behind Elliott while the two-time rushing champion was gone, had his first 100-yard day (103), clinching it on a 16-yard run for his first touchdown.

The Dolphins outgained the Cowboys in the first half (216-204), but still have just one touchdown in three games after settling for two field goals from Jason Sanders in four trips inside the Dallas 30 before halftime.

Just before Drake’s fumble, DeVante Parker dropped a throw that he easily could have turned into a touchdown. Parker earlier had a one-handed grab on a drive that ended in a 47-yard miss by Sanders.
