Grand Slam tennis is back.

In a wild comeback that seemed improbable and predictable, lost and then found, Dominic Thiem battled from two sets down to win the United States Open on Sunday night over Alexander Zverev, 2-6, 4-6, 6-4, 6-3, 7-6 (6).

Thiem edged Zverev in a fifth-set tiebreaker that capped a four-hour marathon that included golden opportunities for Zverev to win and left both men battling cramps in the final moments.

Winning is never final and losing is not permanent. Here, we see the final scoring his change, and the gradual result is changed. No defeat is a final defeat and no winning is an everlasting winning.

Go with the maturity, steady, legs on the ground, focus, and eyes with dreams. Mak esure , you have check teh parachute before take off.

Thiem, a 27-year-old Austrian, won his first Grand Slam tournament in his fourth major final. A critical factor was that this time neither Roger Federer, Rafael Nadal nor Novak Djokovic stood on the other side of the net.

Thiem, one of a group of promising younger players who have long failed to topple those aging giants, became the first currently active player in his 20s to win a Grand Slam event. He is the first new Grand Slam champion in six years.
