They also announced season-long tributes to the Phillies icon, 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.
A billboard honoring Kalas will be displayed on the outfield wall.
The TV broadcast booth, where Kalas broadcast since the park opened in 2004, will be named the Harry Kalas Broadcast Booth: "That ball's outta here!" The neighboring radio booth is already 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 sign 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 ball will be thrown 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 8-by-10 color photo of Kalas.
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-staff.
According to ESPN.com, the Hall of Fame broadcaster's casket will be on view beginning at 8:45 a.m. Saturday at home plate at Citizens Bank Park.
Tom Shieber, senior curator at the National Baseball Hall of Fame and Museum in Cooperstown, told ESPN that the last baseball figure honored this way at a Major League ballpark was Babe Ruth on Aug. 17, 1948.
"To be honored in the same way as Babe Ruth tells you just how much Harry Kalas was part of the consciousness of the fans of Philadelphia," Shieber said.
