The Brewers optioned Topa to Triple-A Nashville on Sunday.
Topa will cede his spot on the active roster to pitcher Eric Lauer, who was reinstated from the COVID-19 injured list ahead of his scheduled start Sunday against the Pirates. After being activated from the 60-day injured list Wednesday, Topa made two appearances out of the Milwaukee bullpen, giving up five earned runs on five hits across 1.2 innings.
