MADRID — The first battle of starting quarterbacks from Saint Louis School went to Tua Tagovailoa.

Tagovailoa and the Miami Dolphins edged Marcus Mariota and the Washington Commanders 16-13 in overtime on Sunday, in what was also the first NFL regular-season game in Spain.

“I got a chance to speak to him after the game,” Tagovailoa said of his friend from Oahu. “After I told him great job, great seeing him. (It was) more of things that he wanted to share with me that I really appreciated.”

Jack Jones intercepted Mariota on the first offensive play of overtime and Riley Patterson kicked a 29-yard field goal to give the Dolphins the victory at Real Madrid’s Santiago Bernabeu Stadium.

“They covered our first couple options well,” Mariota said. “I tried to get backside to Zach (Ertz), a guy undercut it and made a play. Unfortunate there, and give credit to him. He made a good play.”

The Commanders (3-8) had a chance to win with 15 seconds left in regulation, but Matt Gay’s 56-yard field goal attempt sailed wide right.

The Dolphins (4-7) were twice stopped on fourth-and-goal, including inside the final two minutes after recovering the ball on an earlier muffed punt return by the Commanders. The muff came after the Commanders were stopped on fourth-and-goal the other way.

It was the seventh — and final — international game this season, the most in one year for the NFL as it continues to expand globally.

“I think we’re very grateful to have played the first game out here in Spain,” said Tagovailoa, who improved to 1-1 against fellow quarterbacks from Hawaii this season. Miami lost 31-6 to Dillon Gabriel and the Cleveland Browns on Oct. 19.

The game in Madrid saw Puerto Rican superstar Daddy Yankee and Argentine producer Bizarrap perform at halftime in front of a crowd of 78,610 at the Bernabeu.

Mariota had to temporarily leave near the end of the third quarter to be evaluated for a concussion. He went down awkwardly while throwing the ball away in his own end zone. He eventually cleared concussion protocol and was able to return.

The Commanders, still without injured quarterback Jayden Daniels, have lost six straight, including 44-22 to the Detroit Lions at home last week, while the Dolphins were coming off a commanding 30-13 victory over the Bills.

“It’s a great team victory,” Tagovailoa said. “All wins are good and we are going to carry this momentum along through our bye week and hopefuly take it to our next game.”

Tagovailoa went 14-for-20 for 171 yards passing without any touchdowns or interceptions.

Mariota went 20-for-30 for 213 yards with a touchdown and the interception in overtime. He also had 49 yards rushing, including 44 on a run not long after he was taken to the blue tent to be evaluated for a concussion. He said afterward it was a stinger on his right side.

Chris Rodríguez rushed for 49 yards for the Commanders, and Deebo Samuel had 74 yards receiving.

De’Von Achane had another big game for the Dolphins with 120 yards on 21 carries, plus 45 yards on five receptions.

After both teams exchanged a pair of field goals in the first half, the Commanders put together a strong drive to begin the third quarter. Washington scored the first touchdown of the game on a 20-yard reception by Samuel, who took advantage of some good blocking up front after a screen pass by Mariota.

The Dolphins tried to respond quickly and drove to the Commanders 2-yard line, but failed to score after an incomplete pass by Tagovailoa to Jaylen Waddle on fourth down.

After the Commanders were held on the drive in which Mariota got injured, Miami put together another strong possession and Ollie Gordon scored on a 1-yard run.

Mariota led the Commanders to the 1 after clearing the concussion protocol, helped by a 44-yard run on which he sped through the right side with seven Dolphins trying to catch him. But the Commanders quarterback couldn’t close out the drive with a score, throwing an incomplete pass after tight end Ertz tripped near the end of his route on fourth-and-goal.

The Dolphins were held on the next drive, but Mike Sainristil muffed the punt and Ethan Bonner recovered for Miami at the Commanders 42 with about four minutes left. After Achane couldn’t get in from the 1 on third down, coach Mike McDaniel went for it on fourth down but the Commanders made another big stop as Gordon also failed to get in.

Achane was injured on the third-down play, but walked off the field on his own.

Washington took over with 1:41 left in the game at the 3 and Mariota led the team into field goal range, but Gay couldn’t convert what would have likely been a game-winner.

Mariota dropped to 1-4 as a starter this season.

“At the end of the day, all these trials and tribulations that we’re going through is ultimately going to build us better,” Mariota said. “We just kind of have to take it on the chin. It is what it is. We’re not where we want to be but the only way we can dig ourselves out of it is learning from these mistakes, learning from these games, and I think we will.”
