Re: Allez Mandy Minella!
Altitude is only one factor, there is also tempeture, humidity, court setup, balls, strings and tension.
Long Island is at sea level and Mandy usually does well at the US Open.
I only remember Mandy playing Jessica Pegula once, losing in Vancouver last year.
Jessica Pegula might be the WTA equivalent to Ernests Gulbis as her dad is extremely wealthy, including owning the NHL Buffalo Sabres.
If you have ever seen Mandy playing on low bouncing grass courts you would know that choosing Eastbourne or Den Bosch makes no difference whatsoever. But England is a nice place to visit.
