These inner-city courts at the crossroads of Allapattah, Wynwood, and Liberty City once were parched and cracked. Thanks to donations from the Ericsson Open tennis tournament, the neglected center recently has come back to life with a million-dollar facelift. New nets and repaved and painted courts currently open only till noon, but with plans to extend hours to seven o'clock each night, promise great matches without a wait. Bring the kids for affordable tennis clinics. After a couple of sets, relax in the clubhouse, also part of the renovation, or watch others play from the comfortable stadium seats.
