The Orioles committed an error yesterday before they took the field for warm-ups.

The lineup card posted outside the coaches office listed Jay Payton and Scott Moore at first base, with no right fielder. Payton was supposed to have the number 9 beside his name instead of a 3. He hasn't played first since his Triple-A days, when he spent half a season there while recovering from his second "Tommy John" surgery.

Payton had a little fun with the miscue, asking utility man Mike Costanzo if he had an extra first baseman's mitt. "Yeah, you can have mine," Costanzo said, smiling.

Payton also joked that yesterday's opponent, the Florida Marlins, didn't have anyone on the team who could hit the ball to right field. They could shoot grounders to the right side - hence the need for two first basemen - but they couldn't hit fly balls.

"Now that's good scouting," he said.
