Antonacci

Antonacci took Tanner Bibee deep in the first inning. The 23-year-old was outstanding in the Arizona Fall League as well, and his plate skills give him a chance of making a debut with the White Sox in 2026. It’s hard to see fantasy-relevancy in 2026, however.

A fifth-round pick in 2024, Antonacci hit .378/.505/.541 with eight extra-base hits and 11 steals in the AFL. The White Sox’s 11th-ranked prospect worked his way up to Double-A in 2025 and could start there in 2026 as well. There is little power in his bat, but he has shown plus contact ability and good speed, and the ability to play multiple positions on the infield.

Antonacci was a fifth-round pick in the 2024 draft and had a solid season in the minors, hitting .291/.433/.409 with five home runs and 48 steals in 116 games split between High-A and Double-A. He’s also gone 6-for-23 in the AFL with seven RBI and three steals in five games. Speed is obviously his calling card here, but if he can continue to hit for a solid batting average as well, he could emerge as an interesting fantasy player.
