Edmonds, who has been on the DL since May 18 with a left oblique strain, did some soft toss and took some swings in the batting cage before Thursday's game. Macha also noted Edmonds will be out for early batting practice on Friday.
Edmonds' return will likely mean the departure of a member of the bullpen, but Macha was not ready to speculate about the move just yet.
"We'll wait for that when it gets there," Macha said.
The news of Edmonds' progress was particularly good for the Brewers considering the uncertainty regarding his return just a few days ago.
When asked about Edmonds during the Minnesota series over the past weekend, Macha said he thought there may be a chance Edmonds would not be back when he was eligible to return on May 31.
"That's encouraging," said Macha, referring to Edmonds' progress. "He's feeling optimistic, so I trust Jimmy because he let me know at the beginning of the year. He said, 'I'll be ready.'"
