Sam Antonacci Is Part of the Future Core for the White Sox
The versatile infielder blends early aggressiveness with balanced patience at the dish. It shouldn't be long before he's showing off those skills in Chicago.

Various types of players can emerge from being minimal-attention prospects to become key players on an MLB roster, and Sam Antonacci is certainly one of them.
This is a guy that I have been high on as a prospect since he was selected in the fifth round of the 2024 MLB Draft, but has now seen his stock rise rapidly over the past nine months or so.
It’s easy to understand why when you see Antonacci’s .433 OBP and 156 wRC+ across 116 MiLB games last season, but his potential impact goes beyond that.
Antonacci has had a rare and impressive path to knocking on the door of his MLB arrival. Following two seasons at Heartland Community College, where he dominated, he spent one season at Coastal Carolina and led Division I Baseball with a .367 batting average.
That standout season led to him becoming a valued draft pick by the White Sox organization, but his true breakout came last year during his first professional season. It continued into the Arizona Fall League and now this spring.
A standout hit tool is the calling card for Antonacci, whose blend of early aggressiveness and balanced patience at the dish leads to consistently strong at-bats. Pair that with nearly 50 stolen bases last season and the versatility to play the entire infield, and you’ve got an enticing piece.
The biggest question mark, particularly when it comes to his ceiling as a player, has been power upside, given Antonacci’s relatively small frame and low power output to this point.
White Sox director of hitting Ryan Fuller is encouraged by the results of Antonacci’s offseason work as it pertains to adding more impact.
“He crushed the weight room, added weight, and utilized our bat speed program…that added strength is going to lend itself to being a more productive hitter,” said Fuller.
Adding strength and bat speed has been a big goal for him over the past year, which was on display in the very first game of spring training when Antonacci crushed the hardest hit home run of his career off the bat at 109.5 mph, topping his previous high by over 3 mph.
Oh, and he unleashed an epic bat flip.
That type of fire has been on display across the past year, but has caught the attention of many leaders within the organization, with multiple noting the value of the juice he brings to the table between the lines.
Antonacci showed that type of fire again by forcing an interference call when given the opportunity to in Wednesday’s game against the Reds.
“Not quite like that. He’s special in that regard,” answered manager Will Venable, when asked by James Fegan if he’s dealt with guys who don’t have an off switch, like Antonacci. “We love to see it. When we think about the identity we’re trying to create, he does those things naturally.”
A rather mild-mannered and humble player off the field, Antonacci brings energy on the field that any team could use.
Although he continues to add impact and strength at the plate, Antonacci’s fit on the roster is complicated by the White Sox having significantly more depth in the infield than in the outfield.
He started to take some reps in the outfield this offseason, with the possibility of more playing time opening up for him if he looked capable out there, but he also could just push the agenda enough to earn time at second over Chase Meidroth.
With his performance between High-A, Double-A, and the AFL at the end of last season, it’s hard to see Antonacci spending much time in Triple-A Charlotte, where he’s expected to open the year.
The White Sox roster is filled with young talents, and despite coming in with much less pedigree than his peers, Antonacci can be a key piece.
Seemingly without another clear leadoff option on the roster beyond Meidroth, Antonacci’s patient approach and bat-to-ball prowess could help him play his way into that role, at least against right-handed pitchers.
He has been somewhat of a hidden gem within the system since being drafted a year and a half ago, but is now simply a clear-cut top-10 prospect in the organization with a shot to make a big impact this year and beyond.
Whether it be in an everyday role at second base, as a rotating backup infielder, or as a true super-utility player, Sam Antonacci is set to bring his play to Chicago this season.
