Played owners son and won first set 6-0 and lost second 7-6. Think the primary issue is that my legs got tired and I stand to upright. Need to get lower. Try to have legs twice shoulder width apart even. Need to practice that. Along with continuing to use a super heavy practice racquet (17 ounces at the moment while just using 12.5 in matches). And double continental grip. Tried the topspin forehand a lot last night and just too many unforced errors. Think flattening it out with double continental is probably better for me. Although maybe with better footwork that wouldn't be the case, who knows.
Also want to eventually add in ankle weights when practicing with ball machine. And the wall may not be as fun but in some ways it's better than a ball machine.
