context_page_description: The Baltimore Orioles are a Major League Baseball franchise based in Baltimore, Maryland. They play in the American League East division. The Orioles started playing in Baltimore in 1954, after moving from St. Louis, where they were known as the St. Louis Browns. The first game of the new baseball season for a team is played on Opening Day, and being named the Opening Day starter is an honor, which is often given to the player who is expected to lead the pitching staff that season, though there are various strategic reasons why a team's best pitcher might not start on Opening Day. The Orioles have used 33 different Opening Day starting pitchers in their 60 seasons since moving to Baltimore. The 33 starters have a combined Opening Day record of 22 wins, 18 losses and 17 no decisions. No decisions are only awarded to the starting pitcher if the game is won or lost after the starting pitcher has left the game.
  The first Opening Day for the Orioles was played in Detroit against the Detroit Tigers on April 13, 1954. Don Larsen was the Orioles' Opening Day starting pitcher that day, in a game the Orioles lost 3–0.
