Andrew Vaughn’s arrival in Milwaukee has marked a season-changing chapter in both his career and in the Brewers' season.

Traded from the Chicago White Sox on June 13 in exchange for starting pitcher Aaron Civale, Vaughn arrived in Milwaukee with a career slash line of .248/.303/.407 with 77 home runs in 610 games. Prior to the trade, Vaughn was struggling in 2025, slashing just .189/.218/.314 with five home runs and 19 RBI in 48 games.

In his 15th game as a Brewer, Vaughn delivered his most dominant performance of the season Tuesday night against the Cubs. He went 3-for-4 with a career-high six RBI, highlighted by a towering 409-foot grand slam that broke the game wide open and extended Milwaukee’s lead.

Vaughn's six RBI set a career high and tied for the second-most by a Brewer in a single game this season. Through his first 15 games in Milwaukee, Vaughn is slashing .375/.439/.771 with five home runs and 21 RBI. Since July 7, his 21 RBI rank third-most in MLB, trailing only the Athletics' Nick Kurtz and the Phillies' Kyle Schwarber.

Milwaukee’s 9–3 victory sealed its third straight win against the Cubs, putting it two games ahead of Chicago atop the NL Central.
