Things that jumped out or confirmed to me:
- Solid, high percentage/location first serve is key. Many think they need the big 130 mph single serve but it's counter productive.
- Other successful ways to play than the traditional two up, serve and volley; even at this level.
- Teamwork. Obvious but Lopez and Gronollier really mix it up.
- Pay attention to opponents; recognize and go after guy tightening up. (Stepanek crumbled in quarters tie-break.)
