Corey Seager took the stage to thunderous chants of "M-V-P!, M-V-P!" as the Texas Rangers celebrated the franchise's first World Series championship.

"Really this was truly special, we appreciate all of your support," Seager, the second-time World Series MVP, said during Friday's ceremony following a two-hour parade along a 3.2km-route near the team's ballpark.

Arlington fire officials estimated 400,000 to 700,000 fans attended the celebration.

While normally pretty stoic, though he had a couple of emphatic shows of emotion during the playoffs, Seager took a swipe at the Houston Astros, the team that took the AL West title from Texas on the final day of the regular season.

That made the Rangers a wild-card team, and they then set an MLB record by winning all 11 of their post-season road games.

"You know, everybody was wondering what would happen if the Rangers didn't win the World Series. I guess we'll never know," Seager said, a clear retort to what Astros third baseman Alex Bregman said to start their champagne celebration when they clinched the division title.

Texas beat the Astros in the AL Championship Series, with the Rangers winning all four ALCS games played in Houston, including the Game 7 clincher.

Fans were stacked dozens deep at some spots during the parade, which came two days after the Rangers wrapped up the World Series title with a 5-0 win on the road in Game 5 against the Arizona Diamondbacks.

It came a week after Texas won the series opener at home on an 11th-inning homer by Adolis Garcia after Seager hit a two-run homer in the ninth inning to tie the game.

"Years from now, I'm going to think about this moment, and I'm going to cherish the time that I had to spend with (these players)," manager Bruce Bochy told the crowd. "We talked about it at spring training. We're going to do something special. Well, fellas, we did something special here together. Thank you."

The Rangers won their first championship in their 63rd season as a franchise, which began as the expansion Washington Senators in 1961 before the team moved to Texas in 1972.

AL Championship Series MVP Garcia, Seager and all of the Rangers players were in the parade through the entertainment district of Arlington.

Seager was also the World Series MVP in 2020 when playing for the Dodgers, who won that title in a neutral-site MLB postseason played during the COVID-19 pandemic at Globe Life Field, the Rangers' retractable-roof stadium that opened that season. There was no celebration parade in Los Angeles that year.

This is Bochy's fourth World Series title. He won three with the San Francisco Giants, the first in 2010 with a Game 5 clincher in Texas. Bochy was named the Rangers' manager a year ago, when the team was coming off its sixth consecutive losing season.

"I've been asked: Hey, does this ever get old. It doesn't get old, trust me," Bochy said.
