Playing with guys is completely
different than when you hit with girls – more topspin, deeper more powerful shots and ESPECIALLY more of the topspin-looper type shots that force you to hit w/open stance. Lots of girls hit flatter and tend to put the ball more in the "strike zone" so to speak (somewhere between base/service line) and it's harder to practice hitting off balance, off your wrong foot, etc. etc. – so I really hope she can have a consistent hitting partner.
Serena has a guy hitting partner right? Which has probably helped Serena greatly w/control, power, and reaction time as well since a lot of guys have longer reach/better athleticism.
Playing with guys always scares me
I'm just like WHAT? HOW TOPSPIN??
Guys' overheads/serves are always really powerful as well. So I can't lob them at the net and if I do by accident I just back up and try not to get hit.
