What happened between this Great Ball and Pyroar?

Apr. 19, 2018

After some time, I threw a Great Ball and it made a whistling sound, took one big spin, and clicked. Does this mean Pyroar is more friendly or is it just a rare occasion?

I caught Necrozma in a Quick Ball so I still have my Master Ball. (IDK why I put this here)

Since Generation V, when a Poké Ball is thrown, a special type of capture that is much more likely to catch a Pokémon, called a critical capture (Japanese: 捕獲クリティカル critical capture), may occur. When a critical capture occurs, the Poké Ball will make a high-pitched whistling sound as it is thrown, then pause in mid-air, and shudder before it drops down to the ground, shaking only once on the ground before the Pokémon escapes or is caught.

SourceMaybe it was a critical capture.
