It seems a decision made by coach Craig Tyzzer could have contributed to Ash Barty’s early departure from the US Open last week, although fatigue was also a factor after the Aussie won the title in Cincinnati ahead of Flushing Meadows.
We put full poly in her racket for her third-round match in the hope that she could just get a little bit more feel. It took a bit of weight off her serve, which is not ideal for her, just to give her that confidence in being able to hit off the ground and play. Craig Tyzzer
The different conditions between the two events also played a role, but Tyzzer has since revealed he made a tactical and technical change that impacted the World No 1’s serving before her shock 3rd-round loss, although he stressed the change-up had not cost his charge the match against an inspired Shelby Rogers, adding there were no excuses from Team Barty.
With both Barty and Tyzzer finding the conditions at Flushing Meadows vastly different to where the top seed won her 5th title of the season in Cincinnati, the coach opted to change the top seed’s racket strings before playing Rogers.
“Look, it was super different conditions,” Tyzzer told AAP. “The men use a different ball to the women at the US Open, and the women’s ball is really light and it gets faster.
“All the stats show that most of the girls, when the ball got older, their actual shots got faster.
“It was super tough to control the ball and to keep it in the court and I actually, for her third-round match, took the [natural] gut out of her racket because she was struggling in the first two rounds to keep the ball in court.
“I mean, she did a great job getting through. She literally could not get the ball up and down with any sort of spin.
“So we put full poly in her racket for her third-round match in the hope that she could just get a little bit more feel.
“It took a bit of weight off her serve, which is not ideal for her, just to give her that confidence in being able to hit off the ground and play.”
With Barty making a raft of unforced errors in dropping the opening set 6-2 to Rogers, the tinkering may have affected the title favourite’s rhythm, but while he took full responsibility, Tyzzer said neither he or Barty blamed the change for her defeat.
“The conditions suited players who are counter-punchers and stay up on the baseline and hit flat because the courts are dead, but the ball is pretty lively, and flies through the court,” Tyzzer said from quarantine in Melbourne.
“But, in the end, it wasn’t down to that. She was just physically and mentally exhausted; completely done.
“She just didn’t have anything left in the tank, unfortunately.”
Asked if Barty was cranky at all with him, Tyzzer said: “Look, she probably could be but it was more that I just wanted to ease her mind about having feel and playing with the conditions.
“It wasn’t her decision – it was my decision.
“In the end, I don’t think it cost her the match because she’d basically gone 6-1, 5-1 [up in the second and third sets] playing the right way, and just ran out of steam.
“I think the decision was right with the string because she was able to do more of the things that she wanted to do, other than, probably, serve better.”
