was bowling league tonight using my Enriched Uranium had it now approx 2 weeks

in about the 5th frame noticed what looked like a long scratch , which I thought it was at first two frames later ther where 2 more going almost halfway around the ball both cross above the fingers making an x I put the ball away not wanting to make it worse.
a teammate says they are just scratches but one has a sharp zig zag pattern to it very unusual for just a scratch the third goes from the left of the fingers towards the center of the grip  they are very noticeable on the ball

has anyone have this happen and how can I tell for sure if the ball is cracked

thanks
