NEW HAVEN, Conn. (AP) - Two ATP Tour officials will inspect the Connecticut Tennis Center next week to make sure the newly resurfaced courts are ready for the Volvo International tournament, which begins Aug. 16.

Player Council president Tim Mayotte and vice president Paul Annacone are scheduled to arrive Monday to play-test the courts, which were redone to prevent a reoccurrence of last summer's problems.

During the 1992 tournament, the surface of the stadium court had to be scrapped and resurfaced because of holes, causing delays and public criticism.

As a result of the failure, all of the asphalt-base courts at the $18 million, 15,000-seat stadium were completely resurfaced with DecoTurf II hard courts, the same surface used for the U.S. Open.
