The 28-year-old Perez lost his 40-man spot earlier in the year after serving as a fixture in recent campaigns. He was hitting just .235/.277/.383 at the time, the third-straight season in which he has fallen shy of a .300 OBP (after barely topping that mark in 2016). Perez has performed better against Triple-A pitching (.290/.372/.523).
Smith, 29, was knocked around in his brief MLB time with the Brewers. He has generated better results at Triple-A, turning in a 2.33 ERA with 9.9 K/9 and 4.3 BB/9 through 77 1/3 innings across 15 starts. Clearly, though, the Milwaukee organization wasn’t convinced that he’d be a significant contributor in the majors down the stretch.
The Brewers still aren’t giving up on Shaw. He has endured a miserable campaign both before and after his earlier demotion, with a cumulative .162/.276/.279 batting line over 228 plate appearances. It’s certainly possible he’ll end up back in the majors, once roster expand if not sooner, but it seems he’s on a trajectory for an offseason non-tender at this point.
