The Milwaukee Brewers finally traded Jonathan Lucroy at the deadline and got back Lewis Brinson and Luis Ortiz from the Texas Rangers. They dealt Will Smith to the San Francisco Giants and got Andrew Susac to replace Lucroy and Phil Bickford. All four of those prospects jump into the organizations top 6, according to MLB Pipeline. One thing that did not change was Orlando Arcia being their top prospect and he will make his MLB debut today.
Jonathan Villar has played 100 games at SS for Milwaukee, and will move to 3B, moving Hernan Perez to the OF. Perez has hit .362 since the All-Star break and I would imagine he will take over RF while Kirk Nieuwenhuis and Keon Broxton split time in CF.
Arcia is hitting just .267 at AAA-Colorado but hit .307 at AA-Biloxi last year with 37 doubles.
If you are looking for a SS to replace Aledmys Diaz, Arcia isn't the worst option but maybe Brad Miller or J.J. Hardy is available and a better fit for your specific needs.
