Zverev Disillusioned After Loss to Fils: "I Lose Too Many Matches When I'm in a Position to Win"

Alexander Zverev continues to struggle with doubts. Since his semifinal victory over Novak Djokovic at the Australian Open in late January, the world No. 2 has won only six of his last twelve matches and has not reached a single semifinal during this period.
During the South American tour, he fell in the quarterfinals in Buenos Aires and Rio de Janeiro, before exiting in the second round in Acapulco and Indian Wells, losing to Learner Tien in Mexico and Tallon Griekspoor in California, respectively.
Against Arthur Fils in the round of 16 at the Miami Masters 1000, the top seed in Florida had a break advantage in the third set and led 3-1, only to lose shortly after (3-6, 6-3, 6-4).
In the press conference, Zverev reflected on his recent weeks of competition and acknowledged a bitter reality that he hopes to correct quickly to regain confidence.
"I think I played better here than in the last few weeks, but today, I had a break lead in the third set—there’s no reason I shouldn’t have won this match.
At one point, I lost four games in a row, or something like that. In Indian Wells, I served for the match, and in Rio, I was up 4-1 in the third set (against Comesaña).
In Buenos Aires, I was up a set and a break (against Cerundolo). I lose too many matches when I'm in a position to win. I need to change that.
Arthur (Fils) is a very powerful player, he can accelerate the ball from anywhere on the court, but right now, I mainly need to focus on myself," he told reporters shortly after his elimination.
