With Alfredo Simon expected to be placed on the restricted list, the Orioles will also call up an additional arm in right-hander Mark Worrell, as well as third baseman Josh Bell. Worrell is not on the 40-man roster and would have to be added, with the most logical corresponding move being transferring second baseman Brian Roberts to the 60-day disabled list.
Worrell will join a bullpen that also added Troy Patton on Sunday in anticipation of what could be a short roster. It's not official, but it's likely Orioles closer Kevin Gregg will start serving a lesser suspension during the Red Sox series, with Gregg -- along with Red Sox designated hitter David Ortiz -- believed to have an agreement that would knock down their four-game suspensions to three. Both teams expect to get official word from the league on Monday.
Worrell's stay could be a short one with Simon only expected to be in the Dominican Republic, to appear in court, for a day. Bell's status --and that of outfielder Matt Angle -- depends on Luke Scott, who was scheduled to begin a rehab assignment with Double-A Bowie Sunday night and could be activated as early as Tuesday.
The 25-year-old Atkins made three starts for the Orioles and pitched to an 8.44 ERA, going just three innings in Sunday's game.
