NL Central rival cuts ties with brother of former Brewers' ace after just four days

Milwaukee Brewers fans know the story of Freddy Peralta quite well by now. Originally signed internationally by the Seattle Mariners, Peralta arrived in Milwaukee as part of the trade involving former Brewers' first baseman Adam Lind.

Peralta burst onto the scene with a historic MLB debut at Coors Field against the Colorado Rockies, spent his early years bouncing between the rotation and bullpen, and eventually developed into a reliable full-time starter and 2x All-Star. A team-friendly five-year extension kept him in a Brewers uniform for a total of eight seasons before he was traded this winter to the New York Mets, prior to reaching free agency.

However, one part of Peralta's story that Brewers fans might not be as familiar with is the fact that his younger brother, Luis, is a big-leaguer as well, and for a brief moment, it appeared as if he was going to factor into this year's NL Central race.

On Monday of this past week, after Luis was designated for assignment by the Rockies, he was claimed by the St. Louis Cardinals and optioned to their Triple-A affiliate, the Memphis Redbirds. However, before he could make his first appearance in the Cardinals' organization, Luis was designated for assignment once again.

Luis, who is four years younger than Freddy, has had an inconsistent run in professional baseball. Earlier in his career, he was a starter, but in 2024, he was moved to the bullpen, where the results were remarkable. That year, in the minor leagues, he posted a 0.94 ERA over 32 relief appearances, where he covered 47.2 innings and struck out 75, good enough for a 14.2 K:9 ratio. His success continued at the major league level, where he allowed just one earned run over 15 games out of the Rockies' bullpen.

Unfortunately, 2025 told a much different story, as ERA marks north of 9.00 at both the major and minor league levels raised serious concerns about his development. Luis opened this season still on the Rockies' 40-man, but was designated for assignment by the NL West club on April 26 without making an appearance in the big leagues this year.

The world of roster moves can be a convoluted one, which leads to situations like the one Luis experienced in the Cardinals' organization this week. It's likely that the Cardinals were interested in Luis as an addition to their organization, but didn't necessarily want him on their 40-man roster. Hence, they claimed him, DFAd him, and are hoping he slips through waivers, which would allow him to remain in St. Louis' organization without taking up a 40-man roster spot. However, since Luis can be claimed by any other team in the coming days, which would land him in his third organization in the last week, such a strategy doesn't seem fair to the player.
