LAS VEGAS -- The Orioles made a minor splash at the Rule 5 Draft on Thursday, when they selected catcher Lou Palmisano from Milwaukee's organization and then traded him to Houston for undisclosed cash considerations. Palmisano was selected with the fifth pick in the Draft and traded shortly afterwards, making his Baltimore tenure exceedingly brief.

Palmisano missed much of the 2008 season after knee surgery, but proved himself healthy in the Arizona Fall League, and the Astros and Orioles reached an agreement before the Draft to select him and send him to his new team. The backstop, who was selected fifth overall, batted .256 with 11 home runs at Double-A Huntsville in his previous full season.

Baltimore made a few picks in the Minor League phase of the Rule 5 Draft, selecting a shortstop and two right-handed pitchers. The Orioles chose shortstop Robert Valido from the White Sox in the Triple-A portion of the Draft. Valido batted .222 with a .267 on-base percentage for Double-A Birmingham last year and went 1-for-24 in a brief stint at Triple-A Charlotte.

With its second selection in the Triple-A phase, Baltimore selected Josh Perrault from Washington's organization. Perrault went 4-2 with a 4.48 ERA at Double-A Harrisburg last season, allowing 74 hits in 66 1/3 innings of work. Perrault also made three appearances at Triple-A, and he'll likely slot in for either Double-A Bowie or Triple-A Norfolk in 2009.

The Orioles made one final selection in the Draft, choosing right-handed pitcher Andrew Barb from Seattle in the Double-A phase. Barb, who was dealt to the Mariners in the 2006 trade for Jamie Moyer, was placed on the restricted list last spring and retired due to personal reasons. Baltimore drafted him with the hope that he may reconsider and resume a once-promising career.

The Orioles also lost reliever Rocky Cherry on a Rule 5 claim by the Mets. If Cherry doesn't make New York's active roster, he'll have to clear waivers and be offered back to Baltimore.
