Brandon Snyder won't graduate from Westfield High School for more than a week, but he's already had his official indoctrination as a professional baseball player.

Snyder, the Orioles' first-round draft pick, agreed to terms Sunday on a deal believed to be worth $1.6 million and then took batting practice at Oriole Park at Camden Yards before Monday night's game. With more than 60 friends and family members cheering wildly, Snyder, a catcher, hit three home runs.

"I was pretty nervous, but it went really well," said Snyder, who will leave later this summer to play for rookie league Bluefield. "The first thing I did was rub elbows with Sammy Sosa, so that's a pretty good start."

Orioles Manager Lee Mazzilli watched Snyder -- the 13th overall selection -- take batting practice and walked away impressed.

"The kid swings the bat. He's got a little juice," Mazzilli said. "He's going to go get some games under his belt. You can't rush a kid like that who has a pretty promising career ahead of him."

Retooling the Roster

The Orioles shuffled five players on their roster Monday. Outfielder Larry Bigbie, who had been at Class AAA Ottawa on a rehabilitation assignment, came off the disabled list and started in left field. To make room for him, outfielder Ramon Nivar was optioned to Ottawa.

As expected, the Orioles optioned reliever John Parrish to AA Bowie to make space for right-hander Chris Ray, previously the closer at Bowie. To make room for Ray on the 40-man roster, the Orioles designated outfielder Napoleon Calzado for assignment.
