Coco Gauff & Jessica Pegula are OUT of the US Open women’s doubles tournament in the first round

In what may be the biggest upset of the US Open so far, Coco Gauff and Jessica Pegula have been eliminated from the women’s doubles competition in the first round.

The pair lost to Canadian and last year’s women’s singles runner up Leylah Fernandez and her playing partner Australian Daria Saville 3-6, 7-5, 6-7 losing 10-5 in the final set tiebreak.

Gauff is the no. 1 ranked doubles player in the world and when paired with Pegula is the second best women’s doubles team worldwide.

The American pair began the match trading serves back and forth, surviving a break point to take the fifth game.

In the sixth game, Gauff and Pegula broke the other pair’s serve to go up 4-2 and never looked back, winning the set 6-3.

They struggled in the following set, going down 1-4 at one point before battling back to make things even at 4-4.

Following that win, they lost three of the next four games, including a 20 point ninth game, to lose the set 5-7.

After trading games back and forth throughout the the third set, the teams went down to a ten point tiebreak where a controversial ‘let’ call by chair umpire Christian Rask disrupted the Americans’ momentum.

At 7-5 in the tiebreak, a piece of debris floated down onto the court in the middle of the point being played. Saville raised her arm, shouting for a let. As Gauff was in the middle of hitting what would have been a point winning shot, Rask called a let and the point was scrubbed away.
