The Baltimore Orioles have agreed in principle with first-round pick Brandon Snyder on a deal believed to be worth $1.6 million. The deal will become official Monday when Snyder, who starred at Westfield High School in Chantilly, takes a physical and is introduced at a news conference at Oriole Park at Camden Yards.

Snyder, 18, likely will begin the season in either short-season Class A Aberdeen or rookie league Bluefield. Snyder, a catcher, hit .574 with three home runs for Westfield this spring.

Back in Action

Outfielder Luis Matos, who fractured his right ring finger on May 10, will begin his rehabilitation assignment Monday with AA Bowie when the Baysox begin a series in Trenton, N.J. . . .

Outfielder Larry Bigbie, placed on the disabled list with a strained left hamstring on May 28, is expected to be activated Monday. Bigbie has been on a minor league rehabilitation assignment since Thursday. He had a home run and double on Saturday.

The 500 Club

Home runs by Baltimore's Sammy Sosa and Cincinnati's Ken Griffey Jr. on Sunday made it only the fourth time in major league history two players with 500 or more career home runs homered in the same game. It last happened when Rafael Palmeiro and Barry Bonds homered on June 12, 2004. Willie Mays and Ernie Banks homered on June 17, 1970. Hank Aaron and Mays homered on May 8, 1970. . . .

Relief pitcher James Baldwin, who pitched a scoreless inning of relief on Sunday, has not allowed an earned run in the 71/3 innings he's pitched for the Orioles.

"I like his experience," Manager Lee Mazzilli said. "He doesn't give in to hitters. He has an idea what he's doing out there."
