Sam Antonacci Fantasy Stats

Chicago White Sox ninth overall-ranked prospect Sam Antonacci has been very consistent throughout his first 87 plate appearances at the MLB level, slashing .268/.376/.394 with two stolen bases, six walks, nine RBI, one home run, two triples, and 12 runs scored. More impressively, his plate discipline has been rock solid, striking out only 10.8 percent of the time (95th percentile), whiffing 17.1 percent of the time (85th percentile), and chasing 23.7 percent of the time (82nd percentile). His xBA is also .322, which showcases that even after the impressive start, he could be in line for additional positive regression. Additionally, Antonacci hit .291 in the minors last year and has hit at nearly every stop of his career, showcasing an overall track record of success that should give fantasy managers confidence he will provide value in most categories. Due to his lack of power, Antonacci remains a better points player than a categories player, but is still useful in all formats and should be rostered across all types of leagues.

After getting called up to the big leagues on April 15, Chicago White Sox outfielder Sam Antonacci recorded just one hit over his first 19 plate appearances. However, the 23-year-old has started to heat up of late, as he's six for his last 18 and now owns a slash line of .233/.351/.433 with one home run, four RBI, and three runs scored across 37 plate appearances. While Antonacci does not profile as a power bat, he's struck out just twice in the big leagues. He also should eventually emerge as a high-end speed threat, as he swiped 48 bags across 116 minor league games in 2025. Antonacci's slow start and unorthodox profile at the plate may lead to him being overlooked in most fantasy formats, but he could be a valuable waiver wire pickup for deeper-league managers.

Chicago White Sox rookie outfielder Sam Antonacci hit his first career home run on Tuesday in the team's 11-5 blowout win over the Arizona Diamondbacks, but it wasn't a traditional home run. Antonacci went 2-for-5 at the plate with an inside-the-park homer, a triple, and three RBI in just his sixth major-league game. It was nice to see the 23-year-old speedster have a good game, as he had struggled at the plate in his first five games with the White Sox. Antonacci, who is considered the team's No. 9 prospect per MLB Pipeline, is now hitting .190 (4-for-21) with three RBI, two runs scored, two walks, and a strikeout in his first six games in the big leagues. There's not going to be a lot of extra-base power from Antonacci in his first year in the majors, but fantasy managers in deeper leagues may want to consider him if they need speed. Antonacci is only rostered right now in 6% of Yahoo leagues, so he's widely available.

Chicago White Sox outfielder/second baseman Sam Antonacci was called up for his MLB debut on Wednesday after posting a .979 OPS across his first 67 plate appearances at Triple-A. However, the 23-year-old has struggled out of the gates in the big leagues with just one hit and one run scored across his first 19 plate appearances. Antonacci is also a speed threat who stole 48 bases in 116 minor league games in 2025, but he's yet to record his first major league steal. On the plus side, Antonacci has drawn two walks and struck out just once. His ability to control the strike zone was one of the biggest reasons for his effectiveness in the minors, as he posted a 13.3% walk rate in 2025. If he continues to make contact and draw walks, Antonacci should pull out of his current skid. He's still a worthy waiver-wire gamble for fantasy managers in need of speed.

The Chicago White Sox officially have recalled outfield/infield prospect Sam Antonacci from Triple-A Charlotte on Wednesday, according to Bruce Levine of 670 The Score. Antonacci will receive his first big-league call-up after going 15-for-48 (.313) with two home runs, seven RBI, five stolen bases, and six runs scored in 14 games at Charlotte. The 23-year-old is ranked as Chicago's No. 9 prospect, per MLB Pipeline, and he could see regular playing time against right-handed pitching in the majors at various positions. Antonacci has mostly played left field in the minors in 2026, but he also has experience at all four infield spots down on the farm. He has a compact swing from the left side of the plate and plenty of plate discipline for a young prospect. There's not a ton of power with Antonacci, but he's worth considering off the waiver wire in deeper leagues for his potential speed contributions. In the long term, second base might be his best path to regular playing time. UPDATE: Antonacci is starting at second base and is batting fifth in his MLB debut on Wednesday against the Tampa Bay Rays.

Chicago White Sox infield/outfield prospect Sam Antonacci holds high-end stash upside among hitting prospects. Reports last weekend suggested that the White Sox were set to call up Antonacci to the big leagues, but since this transaction has yet to occur, the team may feel he needs additional development in Triple-A. Entering the season, Antonacci was not on the stash radar in most formats as he sat as the No. 9-ranked prospect in the system on MLB.com. However, he has performed at an elite level at Triple-A and is beginning to tap into his power upside. Through 14 games with Charlotte, Antonacci has gone deep twice, swiped five bags while holding a .313/.500/.479 line. Last summer, Antonacci hit just five home runs in the lower levels while stealing 48 bases over 116 games. If Antonacci can continue this power trajectory, he could hold 10/30 upside once he reaches the South Side. Given Chicago's current lineup, Antonacci is a top hitter prospect to stash in standard category leagues, given his speed potential.

The Chicago White Sox have not yet decided to promote utility prospect Sam Antonacci from the minors, according to Bruce Levine of 670 The Score. This update conflicts with a previous report from Elijah Evans of Just Baseball, who said that Antonacci would be called up on Tuesday. There has been plenty of confusion about the timeline for his debut, though it does seem like he'll be called up eventually. The 23-year-old game is slashing .317/.509/.488 with two homers, six RBI, four steals, a 24.1% walk rate, a 10.3% strikeout rate, and 171 wRC+ through 12 games at Triple-A so far this season. He also offers defensive versatility with experience playing all four infield spots, plus left field. Antonacci ranks #86 among prospects in Eric Cross' latest dynasty fantasy baseball rankings for RotoBaller.

Chicago White Sox infield prospect Sam Antonacci has yet to make his MLB debut. However, the team is expected to promote him from Triple-A for the start of their three-game set on Tuesday against the Tampa Bay Rays. Antonacci has gotten off to a hot start this season in the minors, hitting .317/.509/.488 with two home runs, six RBI, six runs scored, and four stolen bases across 58 plate appearances. Across 519 minor league plate appearances in 2025, Antonacci got on base at a .433 clip and stole 48 bags. He also hit just five home runs, so fantasy managers should not expect Antonacci to provide much in the power categories. Still, Antonacci should be able to carve out a regular role with the White Sox with even modest production at the plate and could be a valuable source of speed for fantasy managers to target on the waiver wire.

Chicago White Sox infield/outfield prospect Sam Antonacci is slated to be promoted to the MLB roster ahead of their contest on Tuesday, according to Elijah Evans of Just Baseball Media. Antonacci is currently ranked as the No. 9 overall prospect in the team's system on MLB.com. In the 2025 campaign, Antonacci spent his time at both High-A and Double-A, logging 116 total games. During this stint, Antonacci held an overall .291/.433/.409 slash line with 21 doubles, five home runs, and an impressive 48 stolen bases. Through the opening part of the 2026 campaign, Antonacci has moved up to Triple-A, where he has looked quite comfortable, carrying an elite .317/.509/.488 line with two home runs and four stolen bases. While his power upside may be low, he possesses elite speed, which makes him worth adding in all standard 12-team leagues ahead of his upcoming MLB debut.

Chicago White Sox infield prospect Sam Antonacci is a prospect to keep an eye on in deeper season-long fantasy leagues, as the 23-year-old has been riding a hot bat ever since he broke into professional baseball. After being drafted in 2024, he hit .333 and walked (17) more than he struck out (13) in 23 games at Single-A. The former fourth-rounder proceeded to hit well at High-A in 2025, earning a promotion to Double-A, where the same contact skills and patient approach were on display, putting together a .292/.435/.381 slash line there with a 28:32 BB:K in 49 games, with 48 steals between the two levels to boot. Chicago's ninth-ranked prospect went on to collect the most hits in the 2025 Arizona Fall League (28) and has not slowed down one bit in 2026. The left-handed slugger hit .368 in the Cactus League with a pair of home runs, and has hit the ground running at Triple-A, going 7-for-20 (.350) with two home runs, three steals, and a 6:1 BB:K in his first five games. There's a good shot he's called up by midseason, and with eligibility at both 2B and 3B on Yahoo!, his fantasy appeal is even more robust. The Coastal Carolina product is quickly becoming one of the top stash candidates this season.
