They also announced season-long tributes to the Phillies legend, who died Monday at 73 from heart disease.
Some of the notable season-long tributes:
Throughout the season, Kalas' renowned "Outta here!" home run call will be played over the PA system after every Phillies home run at Citizens Bank Park; players, coaches and manager Charlie Manuel will wear an HK patch on their uniforms; and a billboard honoring Kalas will be displayed on the outfield wall.
The TV broadcast booth, where Kalas broadcast since the Bank opened in 2004, will be named the Harry Kalas Broadcast Booth: "That ball's outta here!" The neighboring radio booth already is named the Richie "Whitey" Ashburn Broadcast Booth: "This game's easy, Harry."
In the first half-inning of Friday's broadcast on Comcast Network Philadelphia, there will be no commentary.
During the seventh-inning stretch Friday, a video of Kalas singing "High Hopes" will be shown on PhanaVision. Fans will be encouraged to sing along.
Fans are encouraged to arrive early before Friday's 7:05 p.m. ET game against the San Diego Padres for pregame tributes. The ceremonial first balls will be thrown out by Harry's sons Todd, Brad and Kane. There will be a moment of silence before Kane sings the national anthem. A video of Harry's career will be aired on PhanaVision.
Fans will receive an 8x10 color photo of Kalas.
Beginning at 8 a.m. Saturday, on a first come, first served basis, fans will have the opportunity to pay their respects on the field as they pass by Kalas' casket behind home plate.
Fans will walk by the casket until approximately 12:45 p.m., when everybody will be directed to seats. Beginning at approximately 1 p.m., current and former players, broadcasters, front-office employees, friends and family members will pay their final respects before the on-field tribute begins at 1:30 p.m.
Fans are asked to enter Citizens Bank Park through the Third Base Gate at Pattison Avenue and Citizens Bank Way. They are asked to leave through the First Base Gate.
Fans bringing flowers or mementos should leave them in the area of the Mike Schmidt statue outside the ballpark.
Parking is free, and fans are encouraged to park in the lots west of the ballpark.
Fans in attendance Saturday will receive a commemorative program, an 8x10 photograph of Kalas and a poem written by him in 2002 as a fan tribute.
Kalas' signature will be displayed on the field during the seven-game homestand, beginning Friday. A black drape will appear in front of the Phillies' radio and TV booths. The Phillies flag in Ashburn Alley will be hung at half-mast.
