Ben McDonald, who threw for 12 minutes Monday and felt no pain in his right elbow, will throw 20 to 25 pitches in a simulated game before tonight's Orioles-Royals game.
"It's like he's beginning spring training again," Orioles manager John Oates said.
* Third baseman Craig Worthington (hamstring pull) is reporting to Triple A Rochester today to begin a rehabilitation assignment. His successor at third, Leo Gomez, is 6-for-17 in five games since being recalled from Rochester.
* Oates wants to rest 39-year-old Dwight Evans as much as possible until his strained Achilles' tendon heals. The manager reasons that whenever the Orioles face a tough righthanded pitcher like Mark Gubicza, who mesmerized them last night, it's a good time to give Evans a night off.
