On Friday, Spencer Jones entered American Family Field, spotted his No. 78 Yankees jersey hanging in his locker, and couldn't help but smile. "Best day ever," he said to manager Aaron Boone before getting ready to take on Brewers pitcher Jacob Misiorowski in his Major League debut.
Although Misiorowski’s 100-plus mph fastballs welcomed Jones to the Major Leagues in dramatic fashion, he held his own, going 0-for-2 with a walk in a 6-0 loss to the Brewers.
“A little nervous, a lot of adrenaline, but having my family there was really special,” Jones said about stepping into the batter’s box for the first time. “It was a moment I’ll never forget.”
While the debut ended in a tough loss, what caught fans’ attention was his No. 78 jersey — a number that had never before been worn by a player in Yankees history.
“What this feels like, it’s really special. All the gratitude and being out there, it’s a kid’s game. It was really cool. I think I’ll hold on to how this feels for the rest of my life,” Jones said of his debut.
Selected 25th overall in the 2022 MLB Draft out of Vanderbilt University, the Yankees’ No 6 prospect quickly caught the attention of the front office. The 6”7, 240-pound slugger was a force of nature, hitting back-to-back homers throughout his Triple-A outing.
This season, Jones slashed .258/.366/.592 with 11 home runs and a Minor League-leading 41 RBIs in just 33 games. Across his minor league career, he has posted a .270/.351/.497 slash line with 292 runs, 436 hits, 95 doubles, 11 triples, 83 home runs, 277 RBIs, and 116 stolen bases in 413 games.
Aaron Boone gives a word of advice to Spencer Jones
Despite such amazing numbers, what keeps Spencer Jones on his back foot is his 33.7% strikeout rate. His biggest concern remains his swings and strikeout rate, raising doubts about whether his power can outweigh the swing-and-miss issues.
“Just with his power and his size, there’s going to be swing and miss in his game, that’s part of it,” Boone said. “There’s great players around the league that have that. But I think he’s made real adjustments over the last couple years from an approach, from a swing standpoint. I feel like I saw some of those take hold, especially seeing him on an everyday basis in spring training.”
Still, he showed slight improvement at Triple-A this season, reducing his strikeout percentage from 35.4 to 32.4 after posting 36.8 in 2024.
