Dunlop has become the Silver Partner of the ATP as they also sponsor the year-end tournament Nitto ATP Finals, besides the other prestigious tournaments on tour. As a result of the thinner air, and the pressure difference between the inside of the ball and the air surrounding it, balls generally fly much faster and bounce higher.If you’re looking for one of the best all-round tennis balls, for hard courts in particular, this one is up there. In numerous events, the ATP men use tennis balls which have extra-duty felt ball while the WTA players use a regular-duty felt ball, which means the ATP balls have more felt than the balls used in the WTA domain.

However, players such as Petra Kvitova and Madison Keys , who tend to hit hard, flat strikes that will gather more pace off a lighter ball, have said they like the regular duty ones.The US Open is the only major where men and women use different balls and, in the build-up to this year's tournament, a number of players have echoed Swiatek's comments. The WTA’s decision to use the Wilson Extra Duty tennis ball was made months in advance of the US Open and is a decision based on careful consideration by all parties. It’s a popular choice for lots of players because it’s long-lasting and plays consistently well across different court surfaces and play styles.

Some women have issues with their arm playing with the heavier ball in the mixed doubles so it will be interesting to see how it works out now that everyone is using it in all competitions.In football coaches can shout, even though there's 11 grown men on the field and they should know what to do. Any decision to change or update what has been used in the past is made with the utmost thought and deliberation, after considering the recommendations of the tours and their player councils. I feel like the first couple weeks there are a lot of double faults, because the balls are just kind of flying a bit more,” the world No 8 said.
