Alexandra always keeps at least seven rackets available, including a brand-new one. She uses Jay's Custom Stringing for her stringing needs. Her dealings with the New York company, owned by Jay Schweid, date back nearly three years (to her competition in juniors). Alexandra's racket manufacturer sends her rackets to Schweid and he customizes them so they all feel exactly the same. At various tournaments, there are stringers on-site to do this work, but Alexandra will often hold on to several rackets and send them to Schweid at one time.

Penn is the ball that Alexandra trains with at the Bollettieri Sports Academy.
