Tickets are now available so please visit the link in my profile to get yours. The event will have a very exciting format with friends of mine on the ATP Tour participating. Stay tuned as I announce more players as they’re confirmed. Whether you’re local in Dallas or coming from out of town, we would sincerely appreciate your attendance and support as this will all be going to fantastic cause.」3月7日 7時54分
