allowed to run the baseline??

[Josh Ovens]

i had a game last night. As A1 puts up a jumpshot, my partner call a foul on A2 for fouling B2 after the ball is released and in the air. the shot was good, ball went through the basket.
CALL: my partner reported the foul on A2. he nullified the basket. the coach was ranting and raving, so my partner asked me if the ball was released before he blew the whistle. and i told him," the ball went in, it was released before the foul/ whistle blew." we went ahead and scored the basket and gave the ball to Team B on the baseline. I let him run the baseline, even though the foul was called, the basket was scored. If it was a close game, and a team wanted a foul after a basket to prevent them from running the baseline to put the ball at the spot throw in. it puts them at a disadvantage. so thats what i went with. me and other officials looked it up in the rule/ case book, but couldnt find the senario. can someone help me out to find it?
