Revisiting the Brewers’ Andrew Vaughn trade with White Sox one year after his Milwaukee debut

It's been one year since Andrew Vaughn made his fateful debut for the Milwaukee Brewers, which included a three-run homer off of Yoshinobu Yamamoto, though we're coming up on 13 months since the day he was acquired (June 13, 2025) from the Chicago White Sox. Most will remember the Aaron Civale saga that served as the precursor to his arrival; the right-handed pitcher had demanded a trade after being bumped from the rotation due to underperformance and the arrival of über prospect Jacob Misiorowski.

In a move that reeked of karmic retribution, the Brewers honored his request, sending him to the hapless White Sox in exchange for a post-hype, high-upside play with Vaughn. The former third overall pick in the 2019 draft simply couldn't break through in Chicago, though his potential has never been in question (he skipped Double-A and has a .784 OPS in Triple-A).

Now a fixture in Pat Murphy's lineup, just how much of a win can we call this deal?

Andrew Vaughn has become the poster boy for Brewers' wily trade acquisitions

For what it's worth, Civale is back in a rotation, starting on a regular basis for the Athletics. However, he's been bad with them this season (5.10 ERA, 5.49 FIP) and was arguably worse with the White Sox (5.37 ERA, 4.30 FIP). He did experience a very brief run of success with the Chicago Cubs between those tenures -- which included 4.1 scoreless innings against the Brewers in Game 1 of the NLDS -- but it matters not.

At the end of the day, Milwaukee traded Civale's expiring contract in exchange for a 27-year-old Vaughn who is under team control through 2027. That alone made the deal worthwhile; the first baseman's sterling success in the year since debuting only solidifies the Brewers' status as the winner of the trade.

Thanks to a variety of swing changes after joining the organization, including a more aggressive leg kick and a much shorter swing, Vaughn has become a force at the plate in the big leagues. He's hitting a robust .315/.391/.499 with the Crew, which dwarfs his .248/.303/.407 line with the Pale Hose. After submitting below-replacement-level production with his former team (-0.6 bWAR in 610 games), he's been a near-star-level contributor (2.4 bWAR in 112 games) in his new home.

This year has featured an even more promising effort than Vaughn's narrative-shifting debut in 2025, as he's upped his wRC+ (155 from 142) and is walking more than he's struck out. Sure, it's maybe not ideal when a first baseman only has two home runs through his first 47 games, but you'll take that sacrifice of power when it means that he's getting on base at a near-42% clip.

The Brewers have made a living atop the NL Central by winning these kinds of low-risk, high-upside trades, though their swap of Civale for Vaughn will be hard to top going forward.
