Before the first pitch of the O's home opener (Updated)

For their 57th season and 19th year at Oriole Park at Camden Yards (yep, 19 years have already flown by since the Yard opened in 1992), the Orioles have a full schedule of Opening Day activities planned. First, to give fans plenty of time to enjoy the ballpark before the O's take on the Toronto Blue Jays, the stadium will open at noon on Friday, and you'll be greeted with a free 2010 schedule and car magnet upon entering the gates. And before pre-game ceremonies even begin, fans will be able to enjoy roving musical groups on Eutaw Street and the main concourses and the Orioles All-Access Pre-Game Show with Tom Davis and Dave Johnson in the Bud Light Warehouse Bar from 2:00 to 3:00 p.m. However, fans are encouraged to be in their seats by 2:30 p.m. so they won't miss the start of pre-game festivities hosted by MASN's Jim Hunter. In honor of tradition, Dave Trembley and his O's will come out through the center field gate and make their way up the orange carpet - which will be lined with 100 members of the Baltimore Challenger League, courtesy of OriolesREACH - to take their places between first and second base. Also in honor of a 17-year tradition, one fan will be chosen to represent Birdland as the team's "10th man". Now, we can finally make our way to the first pitch. As part of a celebration of the 40th anniversary of the O's 1970 World Series championship over the Reds, all-time O's Brooks Robinson and Boog Powell will throw out ceremonial first pitches before the start of the game. Additional events to honor the O's second World Series will follow throughout the season. Following the ceremonial first pitch, American tenor Richard Troxell will perform the Canadian and US National Anthems, marking the seventh time the Maryland native has performed the Star Spangled Banner on Orioles Opening Day. Troxell will also sing God Bless America during the seventh inning stretch of the game. Meanwhile during the anthem, a 30-foot by 42-foot replica of the American flag that flew over Fort McHenry when Francis Scott Key wrote the National Anthem will be unfurled over the batter's eye wall in center field. Update: The colors will also be presented by Color Guards from both the United States and Canada prior to the game. The Canadian Forces Colour Guard is composed entirely of sailors from Her Magesty's Canadian Ship Toronto in honor of the Navy's 100th Anniversary. U.S. colors will be presented by the Armed Forces Color Guard. And finally, the National Anthem will culminate with a flyover by the 175th Wing Guard. And all before the official first pitch... So there promises to be plenty to keep you busy before the start of the home opener on Friday, but stayed tuned for more news from the Yard, including new additions to Oriole Park in 2010.
