MILWAUKEE -- The slumping Cincinnati Reds are piling up losses on and off the field.
The Reds removed outfielders Tyler Naquin and Nick Senzel from the starting lineup ahead of Wednesday's 18-4 loss at Milwaukee and placed both on the injured list. They were added without injury designations, an indication that both are sidelined with COVID-19-related issues.
Star first baseman Joey Votto was added to the IL for COVID-19 on Tuesday, although manager David Bell said Votto hadn't tested positive at that point. Bell said Wednesday that Votto would likely be out for "more than a couple of days."
The Reds selected outfielders Albert Almora and Ronnie Dawson from Triple-A Louisville as substitute players to fill the open roster spots.
The last-place Reds had lost seven straight and 18 of 19 heading into Wednesday's game, and now are 3-21.
There was one bit of good news for the Reds.
Right-hander Luis Castillo struck out seven and allowed three hits over 4 1/3 shutout innings for Triple-A Louisville on Wednesday in his third rehabilitation appearance as he recovers from a shoulder strain. Bell said Castillo is expected to make his major league season debut Monday.
