Two additional thoughts watching Isner/Murray at 4-4 in the fourth.
Isner can afford to go after breaks because he gets to sit down for a minute because he has to get up and serve. Otherwise, long points that Murray has to use to hold serve would be pretty good strategy for the Scot. They will take their toll, but Isner gets to sit down before he has to serve.
Problem: If he wins the tie-breaker, he won’t have that advantage in the fifth.
And finally, the magic drug, adrenalin can always do wonders, but for how long
