I feel like this too, stupid decision by León. Ward doesn't stand a chance against Isner or Querrey, Dan might have in my opinion. All going to come down to the doubles rubber, and for us we have to beat the greatest doubles team of all time!! (Although they are in decline since US Open)
A lot of the talk suggests that Edmund will play singles anyway. Ward is in terrible form and withdrew from the Doubles in Maui with a shoulder injury.
In the circumstances I don't think Smith had much of a choice about Evans.
