2026 Fantasy Outlook
After excellent runs at Double-A and in the Arizona Fall League, Antonacci looks like a future big leaguer, but he'll face stiff competition for playing time in the majors in 2026. Antonacci was selected by the White Sox in the fifth round in 2024 and received a $572,500 bonus out of Coastal Carolina. Despite the fact Antonacci has hit five home runs in 139 career games, he has been at least 50 percent better than the average hitter in every league he has played in, thanks to superb swing decisions and bat-to-ball ability. He had a 5.2 percent swinging-strike rate last year as an age-appropriate hitter at Double-A and his contact rates have always been elite. He predictably excelled in the hitter-friendly AFL, slashing .378/.505/.541 with three home runs, 11 steals and more walks (15) than strikeouts (11) in 19 games. Antonacci had 48 steals in 116 games last year, although his prolific base stealing is more the product of good reads and a lot of opportunities rather than plus speed. He figures to spend most of 2026 at Triple-A, with a big-league debut not out of the question. Read Past Outlooks
Signed a one-year contract with the White Sox in April of 2026.
On base twice in debut
Antonacci went 1-for-3 with a walk and a run scored Wednesday against the Rays.
Analysis
Antonacci had his contract selected Wednesday and hit fifth in the White Sox's order while playing second base. He led off the second inning with a single to record his first big-league hit, and he similarly began the ninth inning with a walk to begin a rally. Antonacci should remain a consistent presence in lineup, though he'll primarily play in left field.

Latest Fantasy Rumors
Set to earn promotion?
Antonacci could get promoted to the White Sox's big-league roster in the near future, according to Ken Rosenthal of The Athletic.
Analysis
The White Sox traded Lenyn Sosa to the Blue Jays on Monday, and they needed depth in the infield. A promotion for Antonacci makes too much sense, especially since Chase Meidroth and Munetaka Murakami are playing almost every day on the right side of the infield. Antonacci is out to a quick start to the season with Triple-A Charlotte and could be rewarded with a move to the big-league roster in the near future.
