Bought a Yonex Ezone Xi Rally for my wife last November. She is a 2.5-3.0 player. Since owning this racquet, she has played only once a week with it for about 1 - 1.5 hrs per session. She has taken excellent care of this racquet as well. This weekend, I noticed some paint had chipped off the racquet in the throat area. Upon closer inspection, it was a crack. I plan on sending it in to TW to have them review and forward to Yonex for a warranty claim. Can someone look at a couple photos and let me know if I am on the right track, or if it is actually just a cosmetic paint crack. Looks like a frame crack to me, but would like opinions of experienced eyes. Thanks in advance for any and all opinions offered.
