Hall of Famer Jim Palmer will throw out the ceremonial first pitch at Ed Smith Stadium before Tuesday's game against the Tampa Bay Rays.
Palmer also will sign autographs from 11:30 a.m. to 12:30 p.m. for the first 200 fans in line. Gates open at 11 a.m.
Manager Dave Trembley was asked why the Orioles brought Ryan Adams here instead of another middle infielder.
"He was down here early. He's been down here for a while working out in Sarasota," Trembley said.
"He gives us some depth at second base. I would expect (Justin) Turner to be ready to play maybe in another day. I'm not quite sure. He's a lot better."
Trembley said he hasn't settled on a definite lineup for the regular season, but he's getting close. However, two through six can vary depending on matchups, the opposing pitcher and bullpen, etc.
"That's why I'll probably start moving some guys around maybe this week in the lineup from what you've seen the first few games," he said.
Trembley also repeated that Luke Scott could play some first base, but not in a platoon with Garrett Atkins, who will get the majority of the starts.
One day after throwing two hitless innings for the San Francisco Giants, pitcher Steve Johnson struck out as a pinch-hitter yesterday in the third inning of a split-squad game.
A pinch-hitter? In the third inning?
Apparently, he took some impressive cuts while batting in Friday's game.
