White Sox Designate Dustin Harris For Assignment

The White Sox announced that they have selected the contract of infielder/outfielder Sam Antonacci and recalled left-hander Tyler Gilbert. In corresponding moves, they have optioned left-hander Brandon Eisert and designated outfielder Dustin Harris for assignment. It had been reported earlier this week that Antonacci was likely going to be promoted.

The Sox added Harris to the roster a week ago when Austin Hays landed on the injured list. He got into six games and was sent to the plate 16 times. He drew four walks and recorded three hits, including one double. It’s possible the Sox just viewed Harris as a placeholder while they gave Antonacci more time to get outfield reps in the minors. Antonacci played all four infield positions last year but not the outfield. So far this year, the Sox have used him primarily in left field, with 11 starts at that position.

Harris is out of options and can’t be easily sent back to the minors. He was once a prospect of note with the Rangers but his production in the upper levels was middling. From 2023 to 2025, he was on the Texas roster but mostly kept in the minors, exhausting his three option years. He got into just 21 big league games, producing a .217/.280/.435 line in those. For that same span, he had a .271/.368/.418 line in the minors, which translated to a 103 wRC+. He was outrighted at the end of last year and elected free agency, which led to a minor league deal with the White Sox.

He’ll now head into DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Sox could take as long as five days to field trade interest. Since he has been outrighted before, he would have the right to elect free agency if he clears outright waivers again.

The Sox will see how Antonacci’s bat plays in the majors. He has great plate discipline but not a lot of power. In 688 minor league plate appearances, he has seven home runs, but his 14.7% walk rate and 13.7% strikeout rate are both much better than average. That strong approach has helped him produce a combined slash of .299/.445/.419 for a 159 wRC+.

Antonnaci can play some infield but the Sox have Munetaka Murakami, Chase Meidroth, Colson Montgomery and Miguel Vargas from right to left. Since Antonacci has been playing left field this year, he will presumably jump into the outfield mix alongside Andrew Benintendi, Luisangel Acuña, Tristan Peters, Everson Pereira and Derek Hill. The designated hitter spot can also be used to spread some at-bats around. Lenyn Sosa was getting a decent amount of the DH time but he was traded to the Blue Jays this week.
