(CNN) - He missed Opening Day while traveling in Europe, but President Obama gets his first moment on the mound Tuesday night.
The president will throw out the ceremonial first pitch at the Major League Baseball All-Star Game in St. Louis. The White House said he is taking part to highlight his United We Serve program, with community service the center of the pre-game festivities.
Major League Baseball will honor five community volunteers as part of their "All-Stars Among Us" program. Obama and all living former presidents will appear in a community service video before the game.
After the video is shown, Obama will take the field at Busch Stadium and greet the six St. Louis Cardinal Hall of Fame players. He then will throw the first pitch to Cardinals' All-Star first baseman Albert Pujols.
MLB said the president will wear a specially made glove for his appearance, with a script Obama 44 and an American flag on it. The glove will then be sent to the Baseball Hall of Fame in Cooperstown, New York.
The president will travel to St. Louis after making remarks on the economy in the Detroit suburb of Warren, Michigan earlier in the day.
Obama will become the fifth president to throw out the first pitch at an All-Star Game, but the first in 33 years.
UPDATE: At a photo opportunity with Dutch Prime Minister Balkenende Tuesday morning, Obama was asked if had been practicing for the nationally-televised pitch. "I think it's fair to say I wanted to loosen up my arm," he said. "I just want to keep (the pitch) high."
While this will be Obama's first trip to the mound as president, he has previous pitching experience. He threw out the first pitch at a Chicago White Sox game in 2005, joking at the time that the pitch may not have topped 30 miles an hour, but it did clear the plate.
