2. Jeferson Quero - C
When he was added to the 40-man roster last offseason, many Brewers fans hoped they'd get to see another rookie debut in 2024 in the form of catcher Jeferson Quero. Unfortunately, just like for so many other Milwaukee players, the injury bug had a different plan.
Quero suffered a shoulder injury on the basepaths in his very first career game for the Triple-A Nashville Sounds this season. The result was season-ending surgery, meaning fans will have to wait until at least 2025 for his MLB debut.
3. Tyler Black - 1B/3B
Though he didn't win a spot on the MLB roster out of spring training, most felt it would only be a matter of time before corner infielder Tyler Black would be added to the Brewers roster. Those people would have been right.
Black was added to the Milwaukee roster on April 30th and made his debut that same day, going 2-for-4 with a double. He would play in six more games and tally three more hits, ultimately giving himself a .227/.261/.318 slash line before heading back down to the minors.
The 23-year-old already has little left to prove in the minors. After making his way to Triple-A in 2023, he's excelling there again in 2024 with a .284/.384/.497 slash line with four doubles, four triples, and nine homers. He'll almost certainly get another crack at the majors this year and at some point will end up sticking for good.
4. Robert Gasser - LHP
Another prospect who didn't make the team out of camp but was expected to contribute quickly, pitcher Robert Gasser was called upon to help a battered starting rotation in early May. He was an instant success, starting five games and pitching to the tune of a 2.57 ERA and 1.04 WHIP.
In what has been the story of the Brewers season so far, Gasser felt off after his most recent start and had his pitching arm looked at. While he is still in the process of seeking a third medical opinion, things aren't looking good, to the point that Milwaukee manager Pat Murphy fears the southpaw may be lost for the rest of the year.
