Saturday was a long day, and due to rain we moved the singles Quarterfinal matches indoors. It was against a player I practice with frequently, and though I usually do not have much trouble, he serves and hits huge and can be fairly dangerous at times. The indoor surface at the facility is the most unique I have encountered. It is the slowest and grittiest I have ever seen, and I was having a difficult time adjusting. I was way ahead and early on several shots and making a lot of bad errors. That, combined with my opponent playing better than usual, I ended up going to a tiebreak and was really frustrated and in disbelief. To top it off, I hurt my knee on a slide, and with 2 net cord winners from him in the tiebreak, I found myself down a set.
