Jeferson Quero

Organization Prospect Rankings

• Ranked Milwaukee Brewers #3 prospect in 2024
  BA Grade: 55/High
  
  Track Record: When the Brewers signed Quero out of Venezuela for $200,000 in 2019, they quickly realized he was one of the best international catching prospects in the class. As a 20-year-old in 2023, he was one of the youngest players in the Double-A Southern League. He threw out 35% of basestealers and allowed 1.05 attempts per game, both rates among the best by minor league catchers with at least 50 games caught.
  
  Scouting Report: Quero is one of the best defensive catchers in the minors. Pitchers love throwing to Quero, who is an energetic leader with a high baseball IQ with polished catch-and-throw skills. He’s a good receiver and an agile defender with a knack for blocking breaking balls in the dirt. With his plus arm and quick release, Quero controls the running game well with pop times often under 1.9 seconds on throws to second base. Quero shines with the glove, but his offensive game took a leap forward in 2023 as well to solidify his status as one of the game’s best catching prospects. With a slightly open setup, he has a simple lower half load with a small toe tap, quiet hands and is a good fastball hitter who doesn’t swing and miss often at pitches in the strike zone. He is an aggressive hitter who will need to develop more selectivity, particularly against offspeed stuff, but he has good bat control and added more power to his game in 2023, with exit velocities up to 111 mph and a chance to be a 20-25 home run hitter.
  
  The Future: Ticketed to open 2024 in Triple-A nashville, Quero will likely spend most of the year there, though he could make his major league debut by the end of the season, when he will still be just 21 years old. If he can continue to refine his swing decisions, he has the upside to develop into a plus regular behind the plate.

  Ranked Milwaukee Brewers #6 prospect in 2023
  BA Grade/Risk: 50/High
  
  Track Record: Signed out of Venezuela for $200,000 in 2019, Quero quickly proved to be one of the top international catchers any team signed that year. The pandemic prevented him from playing in 2020, but he had a strong pro debut in the Rookie-level Arizona Complex League in 2021, though he separated his left shoulder and had surgery after the season. In 2022 he took another step forward, reaching High-A Wisconsin as a 19-year-old at the end of the season. Quero was one of just six teenage catchers to bat at least 300 times in full-season ball and was then one of the youngest players in the Arizona Fall League.
  
  Scouting Report: Quero earns glowing reviews for his defense. He has soft hands, receives the ball well and is adept at blocking with his quick, athletic and agile movements. He has a plus arm and a quick release, recording occasional pop times under 1.9 seconds on throws to second base to erase 29% of basestealers during the regular season and 11 of 24 (46%) in the AFL. Quero has the high baseball IQ, attention to detail and energetic leadership style that managers and pitchers appreciate. He projects to be a plus defender, but he's not an empty bat either. Quero has good bat control and contact skills when he's swinging at pitches in the strike zone, though he will need to develop a more selective hitting approach. He has average bat speed with an aggressive, slasher approach geared for line drives. But he has a chance for average power, though it might play below that level because of his approach.
  
  The Future: Quero stands out in an organization otherwise thin on catching. He has the potential to be a league-average regular behind the plate, with a chance for more depending on his offensive growth. He's likely to return to High-A Wisconsin to open 2023.

  Ranked Milwaukee Brewers #7 prospect in 2022
  Track Record: Quero signed for $200,000 out of Venezuela in 2019 and quickly emerged as one of the Brewers’ best players in their class as well as one of the best catchers in Latin America for his year. Quero impressed mightily in his pro debut in the Arizona Complex League in 2021. He demonstrated advanced ability behind the plate, in the batter’s box and an overall maturity beyond his years, but the year ended on a sour note when he had surgery to repair a separated left shoulder after the season.
  
  Scouting Report: Quero earns high marks for his defensive skills. He’s an athletic catcher who is quick and agile, blocks balls well with the soft hands and has the advanced receiving skills to comfortably handle high-octane stuff and steal strikes. He has a plus arm, too, that often records pop times into the low 1.9-second range in games. Quero is a smart player and has a vocal, high-energy style that endears him to managers. He has the attributes to become a plus defender, but he’s not just a glove-only catcher. Quero has a solid grasp of the strike zone, good bat control and advanced contact skills with the ability to use the whole field. His average bat speed is a question mark, but he flashes average raw power when he connects.
  
  The Future: Quero has similarities to Nationals catcher Keibert Ruiz at the same age. Teenage catchers carry plenty of risk, but Quero could be on the verge of a breakout at Low-A Carolina in 2022.

  Ranked Milwaukee Brewers #10 prospect in 2021
  Hitting: 50. Power: 55. Running: 40. Fielding: 60. Arm: 60.
  
  TRACK RECORD: Quero played for Venezuela in the 2015 Little League World Series and emerged as one of the top players in the 2019 international class. He signed with the Brewers for $200,000 and immediately delivered a strong showing in the Tricky League—an unofficial league for July 2 signees—and Dominican instructional league. He reported stateside for instructional league in 2020 and impressed on both sides of the ball.
  
  SCOUTING REPORT: Quero has the tools to develop into a plus defensive catcher. He’s quick and athletic behind the plate with advanced blocking and receiving skills for his age. His plus arm helps him record pop times as low as 1.9 seconds on throws to second base. He also draws praise for his intelligence and vocal, high-energy leadership on the field. Quero has hit well so far in unofficial games, even against more advanced competition. He has a sound approach for his age with a knack for making hard contact and driving the ball well to the opposite field. He has solid-average raw power and good bat-to-ball skills.
  
  THE FUTURE: Quero has yet to make his official pro debut, but he has been an arrow-up player since signing. He’s one of the Brewers’ top breakout candidates heading into 2021.

  Ranked Milwaukee Brewers #19 prospect in 2020
  TRACK RECORD: Quero played for Venezuela in the 2015 Little League World Series, then four years later was one of the top catchers in the country when the Brewers signed him at 16 on July 2, 2019.
  
  SCOUTING REPORT: Quero has a strong, durable frame and a chance to be a plus defender. His blocking and receiving technique are advanced for his age, with quick, athletic movements behind the plate. He also has a plus arm and a fast exchange, which produces pop times into the low 1.9s in games. Quero also draws praise for his leadership and intelligence that should help him as a catcher. Quero combines impressive defense with a promising bat that produced a low swing-and-miss rate as an amateur and hard contact when he connects. He has a good offensive approach for his age and drives the ball the other way well, with the ability to hit balls out from right-center over to his pull side already, so he could grow into plus power.
  
  THE FUTURE: Before signing, Quero didn't have as high of a profile as some of the other catchers in his class, but he has trended up significantly. He has more breakout potential heading into his pro debut.
