With the team at the MLB level deep in a rebuild and years away from competing, prospect development is of the utmost importance to the White Sox moving forward. The organization boasts one of MLB's best farm systems, headlined by top prospects Noah Schultz, Hagen Smith, Kyle Teel, and Braden Montgomery. And while many are familiar with the top prospects, several lesser-known minor leaguers in the White Sox system are also off to strong starts.
William Bergolla, Shortstop, Double-A Birmingham Barons
Acquired in last year's Tanner Banks trade with the Philadelphia Phillies, William Bergolla has done nothing but impress since joining the White Sox organization. The 20-year-old left-handed hitting infielder opened eyes in spring training and has continued that positive momentum into the season with the Double-A Birmingham Barons.
Bergolla enters the day hitting .313 with a .389 on-base percentage, .764 OPS, and a 131 wRC+. He has also stolen 11 bases while striking out at just a 12% clip. Bergolla stands small in stature at just 5'9 and 165 pounds and hasn't shown much power yet. However, his walk rate is nearly 10% and he plays a premium defensive position at shortstop. At just 20 years old and almost four years younger than the average Double-A player, Bergolla is already holding his own against much older competition. He is currently the #15 prospect in the White Sox organization but figures to keep climbing the rankings because of his strong start.
Andrew Dalquist, Pitcher, Double-A Birmingham Barons
As the team's former third-round pick in 2019, Andrew Dalquist has been in the White Sox organization for a long time. After struggling as a starting pitcher in his first few professional seasons, he moved to the bullpen before the 2024 season and has improved immensely since then.
After putting up a strong 3.06 ERA and 10.0 K/9 in 38 relief appearances with the Barons last season, the 24-year-old, 6'1, 195-pound right-hander has elevated his game even more so far in 2025. He has yet to allow a run in seven appearances at the Double-A level, putting up a 0.57 WHIP, 2.40 FIP, and striking out 11 batters in 12.1 innings. He has also significantly reduced his walk rate and allowed three hits all season. The White Sox could use all the bullpen help they can get at the MLB level, and we could see Dalquist in Chicago sooner rather than later at the rate he's going.
Sam Antonacci, Infielder, High-A Winston-Salem Dash
The White Sox have recently targeted hitters with high on-base skills, and Sam Antonacci is a prime example. The team's fifth-round pick last year, the 22-year-old left-handed hitting infielder has a ridiculous .469 on-base percentage in 20 games with the High-A Winston-Salem Dash. The White Sox #29 prospect can also put the bat on the ball, as he is hitting .275 with a .860 OPS and a 158 wRC+ while playing both second and third base this season.
The 6'0, 193-pound Antonacci is similar to Bergolla in that he has lacked power up to this point. Still, it is hard to argue with a walk rate of nearly 17%. Antonacci has a solid feel for the strike zone, and his ability to play multiple infield positions makes him an intriguing prospect to keep an eye on.
Ryan Galanie, First Baseman, High-A Winston-Salem Dash
Ryan Galanie has no issue with supplying power. The White Sox 13th round selection in 2023, the 24-year-old, 6'2, 215-pound first baseman already has seven doubles, two triples, and four home runs with the Dash in just 21 games, along with a .315 batting average, .565 slugging percentage .922 OPS, and 153 wRC+.
It is worth noting that Galanie is significantly older than the average High-A player, but he was promoted to Double-A Birmingham just yesterday to reward his excellent start to the season. If he continues to hit against tougher competition in a historically pitcher-friendly ballpark, he could put himself on the map and become a viable prospect.
Lucas Gordon, Pitcher, High-A Winston-Salem Dash
Noah Schultz and Hagen Smith aren't the only notable left-handed pitching prospects in the White Sox organization. Lucas Gordon is quickly cementing himself as a name to watch as well. The White Sox sixth-round pick in 2023, the 22-year-old Gordon put up a 2.23 ERA and 1.16 WHIP over 113 innings across 23 starts in Low-A and High-A last year.
Gordon has continued pitching well this year, striking out 21 hitters in 18.2 innings with the Dash and walking just five. He also has a 2.89 ERA and 0.91 WHIP. The 6'1, 193-pound Gordon does not have overwhelming stuff and is currently not among the team's top 30 prospects, but he remains an intriguing pitching prospect at the lower levels.
Clete Hartzog, Pitcher, High-A Winston-Salem Dash
Clete Hartzog wasn't even drafted, but overcoming the odds hasn't been difficult for the 23-year-old, 6'1, 183-pound right-hander. He has put up a sparkling 1.08 ERA, 0.84 WHIP, and 9.7 K/9 in seven appearances with the Dash. Hartzog is another player older than the average High-A player, but he has performed well so far and could be a future bullpen arm in Chicago.
Lyle Miller-Green, First Baseman, Low-A Kannapolis Cannon Ballers
Tim Elko has been a leading storyline in the White Sox organization recently, and they may have found another version of him. Lyle Miller-Green carries many similarities. Miller-Green was drafted in the 17th round last year and signed a meager signing bonus, but that hasn't stopped him from mashing.
The 6'5, 237-pound right-handed hitting Miller-Green has played primarily first base and left field this season and has mashed with the Low-A Kannapolis Cannon Ballers. In 15 games, he has a .278 batting average, a .519 slugging percentage, and a .919 OPS. He will have to prove himself against better pitching, but his professional career is off to a strong start. If he keeps hitting, he could defy the odds like Elko has.
Javier Mogollon, Infielder, Low-A Kannapolis Cannon Ballers
Javier Mogollon has gotten off to a strong start with the Cannon Ballers despite being over a year and a half younger than the average Low-A player. The 19-year-old, 5'8, 160-pound right-handed hitting infielder was an international signing in 2023 and has a .410 on-base percentage and .887 OPS in 84 plate appearances over 19 games. He also has five doubles, two triples, two home runs, and seven stolen bases while playing second and shortstop. He currently ranks as the White Sox #24 prospect and will undoubtedly move up the list soon.
Caleb Bonemer, Infielder, Low-A Kannapolis Cannon Ballers
Arguably the highest-upside player of anyone in this group, Caleb Bonemer was the White Sox second-round pick last year and has gotten off to a scorching hot start in professional baseball. The 6'1, 195-pound, right-handed hitting infielder is hitting an impressive .313 with a .446 on-base percentage and .961 OPS in 18 games. Bonemer already has six doubles, two triples, a home run, seven stolen bases, and 12 walks in 83 plate appearances while playing shortstop and third base with the Cannon Ballers.
Bonemer, the White Sox #11 prospect, could soon become a top 100 prospect in MLB because of his strong start. His upside is immense, and he is a player worth keeping an eye on as the White Sox look to rebuild their position player talent in the minors.
White Sox Future Is Coming
Unlike the last rebuild, which was very top-heavy and had minimal reinforcements after the big-name prospects, the White Sox organization has more talent throughout the minor leagues than it has had in a long time. There are interesting players at every level, and more are soon coming with the draft this July. It will take a long time for the big league club to become relevant again, but developing talent throughout the organization is a big piece of the puzzle. They seem to be on the right track.
