Negative lift on golf ball simulation

I am attempting to simulate a spinning golf ball traveling through air at a certain speed. I tried employing the Moving Reference Frame (MRF) method, which involves two domains: an outer domain and an inner domain (the rotating domain). However, after calculation, the lift for the golf ball was determined to be negative, opposite to what was expected. I am unsure where I went wrong. Please provide guidance on resolving this issue. The flow speed is 18.46 m/s, and the golf ball is spinning at 1000 rpm. The mesh and solution setup are depicted in the picture below
