The Baltimore Orioles will be raising single-game ticket prices in 2011, even though the team is coming off its 13th consecutive losing season.

The increase is between $1 and $8 per seat, with an average of $3. The increase is the first for the team since 2007 — for games not involving the New York Yankees or Boston Red Sox.

Tickets purchased before the day of a game will cost between $9 and $60. On game day, those prices will increase.

Games involving the Yankees and Red Sox will cost between $11 and $99.

Season-ticket prices are unchanged from 2010.
