Brewers Call Up Quero From Nashville, Vaughn Lands on Injured List

Jeferson Quero, the 23-year-old Venezuelan ranked as Milwaukee's No. 8 prospect by MLB Pipeline, made his long-awaited Major League debut after being recalled from Triple-A Nashville on Saturday, prompted by first baseman Andrew Vaughn fracturing the hamate bone in his left hand on Opening Day and landing on the 10-day injured list.

Vaughn will undergo surgery Monday in Milwaukee, performed by Dr. Tony LoGiudice, and is expected to miss four to six weeks. The injury crept up on him overnight. "I think it happened in my first at-bat," Vaughn said. "I went home that night and felt kind of fine. My hand was a little sore. I woke up in the middle of the night and it was barking. It was like, 'Something's not right.'"

Summoning Quero gives the Brewers a right-handed bat and the flexibility to slide veteran Gary Sánchez from behind the plate to first base when needed. Sánchez, signed to a major league deal late this offseason, carries just 16.2 career innings at first base, including 12.2 with the Brewers in 2024. The arrangement could also open a designated hitter slot on days the lineup allows, for either Sánchez or Quero.

The call-up caps a comeback that manager Pat Murphy described with unusual candor. Quero appeared set to debut in 2024 as Nashville's Opening Day catcher, but suffered a major shoulder injury diving back into first base in the very first game of that season and missed the rest of the year. A hamstring strain further delayed his 2025 season. "It's a great story," Murphy said. "That surgery is way more serious than maybe any surgery you can have for a baseball player. For him to respond to the point where he can be as good as he is today is remarkable. He was an elite thrower before the surgery. He's not an elite thrower now, but he's made due. It's an incredible journey."

Over six minor league seasons, Quero is a career .275 hitter with 39 home runs and 171 RBIs in 279 games. Last season in Triple-A Nashville he posted a .271/.361/.478 line with 11 home runs, 17 doubles, 32 walks and 40 strikeouts across 69 games, a recovery season strong enough to reestablish him as a prospect with everyday potential and All-Star upside behind the plate.

The promotion came just one Triple-A game into 2026. Friday night in Nashville, Quero was behind the plate as Robert Gasser struck out 11 batters over 5 2/3 innings in a rain-shortened 6-4 loss. Less than 24 hours later, Quero was headed to Milwaukee instead. "It was a long road to get here, but everything that happened makes this moment more exciting," he said.

Nashville loses its Opening Day catcher after a single game, a reminder of how thin Milwaukee's catching depth runs below the major league roster. The Brewers allowed Danny Jansen to walk in free agency this offseason and entered the year with William Contreras and Sánchez as their big-league catching tandem. With Quero now in Milwaukee, there is no experienced veteran between the major league club and Triple-A at the position.

In his first week, the metrics worth tracking are whether Murphy pairs him with Contreras in a shared workload or uses him sparingly as a backup, how his bat translates against major league pitching after posting strong Triple-A numbers in a hamstring-shortened season, how reliably Sánchez handles the transition to first base in an emergency role, and whether the surgically repaired shoulder invites opposing baserunners to test his arm from the start.
