The shooting took place just before 8pm on Friday at the Francis Myers Recreation Center on 58th Street and Kingsessing Avenue.
Investigators were seen looking across the basketball court for evidence.
Police said the 17-year-old boy had been shot in the chest once.
The teenager, whose identity remains unknown, was transported by police to Penn Presbyterian Medical Center, where he was pronounced dead a short time later.
No weapon has been recovered from the crime scene, officials said.
No arrests have been made.
Not far from that scene, on 55th and Christian Street, patrols around another recreation center, the Christy Recreation Center, were ramped up after 16-year-old Kahree Simmons was shot and killed on the basketball court on Thursday.

Police said that in that case, four men exited a small SUV and started shooting, hitting Simmons and two other teenagers who were playing.
Action News spoke to his family earlier on Friday.
“Kahree was loved. He didn’t deserve this, he didn’t do anything. He just left the house and played basketball with his friends. That was it,” said Kahree’s brother Stephen Simmons.
They beg for help for an arrest.
“I beg anyone who hears me now to think about it if it was your child. We were just like you, see it on the news and never thought it would be our situation, but today it is our situation,” said Stephen Simmons.
Also on Thursday, the security video captured the sounds and part of a quadruple shooting at block 1400 of N. 76th Street in Overbrook Park.
Another 16-year-old was killed, as well as a 24-year-old man.
Speaking at a press conference on the rec enter on 55th and Christian, Mayor Jim Kenney said the city will begin weekly updates on the gun violence epidemic.
“The briefings will be open to members of the media and publicly streamed on the City of Philadelphia Facebook page,” said Kenney.
While police were investigating Kingsessing’s murder, a fire broke out across the street.
The fire started just before 9pm when smoke was seen from a two story duplex.
Crews brought the fire under control within 15 minutes.
There were no injuries in the fire.
