A close fought match saw the momentum swing between both sides, but eventually it was Cilic who completed the victory as he beat Murray 6-5 (7-3).
Ivanisevic's tie-break victory over Carlos Moya added to a win in the mixed doubles for the Royals, who won overall despite losing the men's doubles.
Jo-Wilfried Tsonga and Treat Huey gave the Mavericks their first win, and Maria Sharapova ensured the match went to a deciding set after beating Mladenovic 6-5 (7-3).
However, Murray was unable to complete the comeback as Cilic powered his way to victory to put the Aces top of the pile after the opening round of fixtures.
