Query: Build Quality

Got this ball last night. The grip felt very good. Took a couple of dribbles on the hardwood floor down in the basement, to my surprises, one of the panels started to tear, showing yellowish color from the edge. It's quite a disappointment given I'd been waiting for this ball for almost a week and was ready to get some play time with it this saturday. I am returning it now and going to my local store to find a wilson ball now... btw, I am not sure if it is an issue with spalding quality control. The spalding official street ball I bought more than 10 years ago still shows no sign of any tear.
