Newly minted Oriole Manny Machado is expected to arrive in Baltimore tonight and will undergo a physical on Thursday and Friday, but will not be introduced to the crowd at Camden Yards for another two weeks.

Machado, a Miami prep shortstop who signed a $5.25 million deal Monday night as the third overall pick in the 2010 draft, will likely be introduced at Camden Yards during the Orioles-Tampa Bay Rays series on either Sept. 3 or Sept. 4.

That’s when he’ll have his official news conference, though Machado will likely speak to the local media via conference call Friday or Saturday, once his contract is signed.

The delay in his introduction and news conference is because he wants his mother, who recently had surgery and cannot fly, to be part of the festivities.

“He wants her to be present, as she should be, and that’s the delay,“ said Orioles amateur scouting director Joe Jordan. “That’s all it is and we are just accommodating that.”

Because Machado, 18, is under age 21, Major League Baseball requires parental consent for the signing of a contract. Therefore, Machado won’t officially sign the dotted line until he arrives home in Miami either Friday night or Saturday. An Orioles scout will be on hand for the signing.

Machado will then report Sunday to the club’s minor league complex in Sarasota, Fla. He will join the Gulf Coast League Orioles and work out with the team, but there is no timetable as to whether he will play this season.

“We are just getting him in uniform, getting him on the field, getting him to work out, seeing what kind of condition he is in,” Jordan said. “They all think they are in great shape, but like any player, we are going to work him out, and see how his body responds, see if there is any soreness, and that will dictate if and when he will play in a game. We are really in no hurry whatsoever.”
