Vaughn Grissom’s big league debut was like something out of a dream. Playing the Red Sox at Fenway Park in August of 2022, the then-Atlanta Braves rookie stepped to the plate in the bottom of the seventh and hit a towering home run over the Green Monster to effectively seal the win.

Two years later, Grissom will now call Fenway Park home as his big league career truly begins.

“I’m really excited, it’s pretty funny how full circle (it is),” Grissom said. “It’s really fun, the stadium was obviously the first one I’d played in and seen, and I was in a dream state. I have a pretty good recollection of what everything looks like and feels like from second base, so that was pretty cool to obviously get the call and to get the call from a team like that where everything started for me.”

Acquired last week in exchange for veteran left-hander Chris Sale, Grissom was officially introduced as the Red Sox newest infielder on Friday. After two years scrapping for playing time amid Atlanta’s All-Star laden infield, the 23-year-old is now expected to immediately slot in as Boston’s starting second baseman.

“Just to get a shot like that is out of this world,” Grissom said, who celebrated his birthday Friday. “If you’d told me when I was a child that I was going to get a shot with the Boston Red Sox by the time I was 23 I would flip out. It’s an amazing honor.”

Grissom comes to Boston with an impressive track record, having dominated the upper minors while posting solid numbers in his limited big league opportunities. In 64 MLB games he’s batted .287 with a .746 OPS, and last year in 102 games at Triple-A he batted .330 with a huge .921 OPS, plus 13 stolen bases and nearly as many walks (56) as strikeouts (66).

He’s also spent a lot of time playing at Boston’s minor league facilities in Greenville and Fort Myers, both of which feature similar dimensions as Fenway Park, and feels his game will translate well to the historic ballpark.

“I’ve enjoyed hitting with the big wall in left,” Grissom said. “I’ve enjoyed hitting in Greenville and I’ve played at JetBlue quite a lot growing up in Florida. It’s pretty cool and I’m in the right hands with the Red Sox.”

Though Grissom doesn’t have established relationships with many members of the Red Sox organization, he noted that he used to play against Triston Casas when they both played high school ball in Florida and have kept in touch throughout their professional careers.

“We’ve followed each other and we’d send each other a text every now and then,” he said. “Then I got traded over and he was one of the first people who reached out.”

Grissom also once had dinner with fellow newcomer Lucas Giolito, with whom he shares an agency, and said his grandmother recently met Alex Cora in Puerto Rico.

As for the rest of his new teammates, Grissom said he’s excited to get to know everyone and plans on taking part in Trevor Story’s upcoming infield defense boot camp.

“He’s one of the guys I was fortunate enough to watch growing up, and now it’s kind of surreal I’ll be playing next to him hopefully,” Grissom said. “I’m going to ask him a ton of questions and feel things and I’m just excited to get to know the boys.”

Then, once spring training comes, he hopes to make the most of the opportunity that now awaits.

“I’m 23, in my Jordan year, so it’s exciting,” Grissom said. “I’m as big and strong — I’ve got a good base going on right now, so I’m feeling grown a little more, the power is coming through. I’m excited to just go out and play man. We’ll let it all play out there but I’m feeling prepared and I hope the Red Sox do too.”
