MIAMI — Even in the early innings, Henderson Alvarez knew he had a no-hitter going. The score, however, left him confused.

When Alvarez struck out Matt Tuiasosopo to end the top of the ninth, he thought he had completed a no-hitter for a 1-0 Miami Marlins victory over Detroit. Alvarez raised a fist and then both arms in celebration.

Oops. The score was 0-0.

That changed a short time later, when Giancarlo Stanton scored on a bases-loaded, two-out wild pitch. The Marlins had a 1-0 win, and Alvarez had his no-hitter on the final day of the regular season Sunday.

“I knew I was pitching a no-hitter early in the game, that it was a gem,” Alvarez said. “I really wanted to finish it.”

He celebrated in the on-deck circle, where he was standing when Stanton crossed the plate because he was due to hit next. After being mobbed by teammates, the 23-year-old Venezuelan went into the stands to hug his pregnant wife and kiss her belly.

Of the 282 no-hitters in history, it was the only one to end on a wild pitch, STATS said. And it was the first walk-off complete-game no-hitter since Virgil Trucks of the Tigers threw one on May 15, 1952, against Washington.

“That’s the beauty of baseball,” Marlins manager Mike Redmond said. “You never know what you’re going to see. On the last day of the season, what a treat.”

Alvarez (5-6) struck out four, walked one and hit a batter. The Tigers played with a patchwork lineup.
