Last night I was playing a league match against a junk-baller. Nothing but slices and dinking spinners. No angles, no pace. I handle him easily through the first set to go up 5-0. Then the wheels fall off. I couldn't serve out the set. Double faults kick in. I barely win the set, but my serve goes to hell. Every shot I hit either goes into the net or lands two feet off the baseline. I went on to lose the whole match. I haven't had this happen in a long time. The turtle went into its shell. Does this happen to anyone else? Is there a support group for this?
