Sam Antonacci Fantasy Stats

Chicago White Sox outfielder Sam Antonacci has played his way into the top waiver mix for managers needing speed, average, and runs. The 23-year-old is hitting .289 with five home runs, 46 runs, 25 RBI, and 12 steals over 253 at-bats. The profile is not built around big power, but it is not empty speed either. Antonacci owns a .380 OBP, has struck out just 15.3% of the time, and brings useful 2B/3B/OF eligibility. That makes him easier to fit than a lot of speed-first waiver options. His 7.5% barrel rate and .370 xwOBA give the bat enough support to keep him in lineups, even if fantasy managers should not expect a major home run jump. With a 47% Yahoo roster rate, Antonacci should be added in most competitive leagues. RotoBaller's latest waiver rankings back him as an add in 10-team formats.

Chicago White Sox rookie infielder/outfielder Sam Antonacci has made an immediate impact in fantasy baseball in his first year in the big leagues in multiple categories, and he should be rostered in more than 53% of Yahoo leagues. Through his first 67 games and 271 plate appearances, Antonacci is slashing .299/.394/.433 with an .827 OPS, five home runs, 12 doubles, two triples, 24 RBI, 11 stolen bases, and 45 runs scored for Chicago. The 23-year-old former fifth-rounder in 2024 out of Coastal Carolina University is one of many reasons the Pale Hose have had a huge turnaround in 2026. Since the start of June, Antonacci has been heating up, too, going 31-for-93 (.333) with four home runs, seven doubles, 11 RBI, 22 runs scored, and three stolen bases in 25 games across 109 plate appearances. His underlying metrics support his strong start in his first year in the big leagues, too, as he currently has an xBA of .301 and an xwOBA of .372 (wOBA of .370). Antonacci can help make your fantasy team better in a variety of ways, and he's eligible at second base, third base, and the outfield in Yahoo leagues.

Chicago White Sox outfielder Sam Antonacci has become a fixture at the top of the exciting young lineup on the South Side. Antonacci is hitting .307 with five doubles, three homers, nine walks, and four stolen bases. He has a .386 wOBA and a .466 SLG, showing he has some very solid power to go with his speed. Antonacci is up to four homers and 11 stolen bases on the season and has scored 37 runs as well. Especially against righties, Antonacci can be a solid source of run creation with the potential to pick up power numbers and add solid stolen base production. He still has multi-positional eligibility in many formats and can be a versatile way to fill in your roster with the potential to contribute across the board, while not hurting your roster in any category.

Across 235 plate appearances in 2026, Chicago White Sox outfielder Sam Antonacci has hit .291/.391/.422 with four home runs, 22 RBI, 37 runs scored, and 11 stolen bases. The 23-year-old does not project to provide fantasy managers with much power, as he owns a 36.4% hard-hit rate and slugged just five home runs across 519 minor league plate appearances in 2025. Still, Antonacci has established himself as the near-everyday leadoff hitter in an underrated White Sox lineup. He's also struck out in just 15.7% of his plate appearances. Between his ability to hit for average and steal bases, Antonacci has a clear use case for deeper league fantasy managers. In leagues where he remains available, Antonacci profiles as a potential breakout candidate to target on the waiver wire.

Chicago White Sox infielder/outfielder Sam Antonacci is becoming a useful waiver-wire option for fantasy managers looking for speed and run production. On the season, the 23-year-old is hitting .278 with two home runs, 17 RBI, 32 runs, nine stolen bases, and a .760 OPS over 208 plate appearances. Antonacci has also taken a step forward over his last 15 games, batting .293 with 12 runs, one homer, seven RBI, and two steals. The power ceiling is limited, so Antonacci is not the optimal target for managers chasing home runs. However, his batting average, on-base skills, speed, and multi-position eligibility in some formats give him practical value in category leagues. His 23% Yahoo roster rate still leaves him available in plenty of formats, making him worth a look for fantasy managers who need runs, steals, a boost in batting average, and flexible positional eligibility.

White Sox rookie outfielder Sam Antonacci has put together an excellent start to his first MLB season, slashing .286/.386/.379 and working his way into everyday lineups. He is hitting .348 in June and appears to be continuing his upward trend with three multi-hit games in his last six outings. He has also added eight stolen bases in 48 games and profiles as a contact-first hitter from the left side. Fantasy managers should take advantage of the opportunity to add him as he looks to build on his early success. His playing time has become more stable as he continues to earn trust within the White Sox lineup.

Across 162 plate appearances since being promoted to the big leagues in mid-April, Chicago White Sox outfielder Sam Antonacci is hitting .275/.369/.362 with one home run, 13 RBI, 23 runs scored, and eight stolen bases. The 23-year-old hit just five home runs across 519 minor league plate appearances in 2025, so he appears unlikely to provide fantasy managers with much power any time soon. However, Antonacci has consistently shown an ability to put the ball in play and has spent considerable time in the leadoff spot for Chicago since making his MLB debut. Antonacci stole 48 bases in the minors in 2025, so he may just be scratching the surface of his speed potential in the big leagues. As long as he can continue to get on base at a solid clip, Antonacci should rack up runs and stolen bases for fantasy managers and is worth a look on the waiver wire.

Chicago White Sox rookie outfielder Sam Antonacci has cooled off a bit recently at the plate, but fantasy managers targeting speed should still be considering acquiring him off the waiver wire. The 23-year-old left-handed-hitting outfielder has hit .233 (7-for-30) with an RBI, two stolen bases, six runs scored, three walks, and seven strikeouts in nine games since May 15, but he still holds a strong .300/.395/.357 slash line with a .752 OPS, four doubles, four RBI, five stolen bases, and 15 runs scored in 21 contests in May. Antonacci, a former fifth-round selection in 2024 out of Coastal Carolina, has only one home run and won't provide much pop for fantasy managers, but he has held his own in his first 35 big-league games in 2026. He's hitting .273 (30-for-110) with a homer, five doubles, two triples, 10 RBI, five steals, and 20 runs scored across his 132 plate appearances. Making him even more attractive in deeper leagues is the fact that he's eligible at second and third base, in addition to the outfield. He's also widely available in Yahoo leagues, as he's currently rostered in just 16% of leagues.

Since making his MLB debut on April 15, Chicago White Sox outfielder Sam Antonacci has proven he's ready for the big leagues. Across 106 plate appearances entering play on Sunday, the 23-year-old was hitting .284/.385/.420 with one home run, nine RBI, 16 runs scored, and three stolen bases. Antonacci's plate skills were one of his calling cards as a prospect, and he's struck out in just 12.3% of his MLB plate appearances so far. While he's just three for his first six as a base stealer with the White Sox, Antonacci swiped 48 bags in the minors in 2025 and should get to more speed in the big leagues over the course of the year. His 10.3% barrel rate also hints at some untapped power upside, although fantasy managers shouldn't expect more than 10 to 15 long balls at the most. Even still, Antonacci offers a well-rounded skill set and has emerged as the everyday leadoff hitter for an improving White Sox lineup. In fantasy leagues where he's not already rostered, Antonacci is worth targeting on the waiver wire.

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.
