Yes, height is an advantage (still, can be countered) but not as significant as the wide disparity in age.
He's really too impatient smashing against LCW too early in the rally. After he does that, he cannot keep up physically @Mark A , I mentioned this tactic before in the other subforum
What I would see is LCW playing a few more drop shots for G3. Depends on his touch from this end of the court.
Fascinating battle.... 1st set Till 8-1 slow badminton without much variation from lcw Then lcw increases pace for next few points and gets back....later tries his variations and uses the frontcourt more...but deficit is too huge 2nd set Just brilliant...uses variations ...not speed
It was a valiant effort to take it to a respectable 3 games...but that's a pretty deep hole to climb out of.
