Matt Capps returned to the disabled list Tuesday after irritating his right rotator cuff during Monday's game against the Orioles.
General Manager Terry Ryan said the Twins will announce a corresponding roster move soon.
Capps was on the DL from June 24 through last Friday with right shoulder inflammation. He made two appearances after returning, but his velocity was down.
The team has shown it can get by with Jared Burton and Glen Perkins handling the ninth-inning, but this news lessens the chances that the Twins will be able to trade Capps this season.
Tonight's game
After scoring a season-high 19 runs Monday, the Twins are going with the same lineup for Tuesday night's game against the Orioles.
If it's not broken...
Jim Thome is back in the lineup for the Orioles, batting third. This is a big game for Baltimore after falling out of the lead for the second wild-card spot on Monday.
