The next opponent for the Americans is Romania Tuesday at 11:40 a.m. (PT).
Bailey's power-play goal with 1:32 left in the first quarter tied the game at 1-1 and Hutten's goal with 7:32 remaining in the second period put the U.S. up, 2-1.
Peter Varellas led the Americans with three goals and Tony Azevedo's goal with 57 seconds left in the fourth quarter proved to be the game-winner as Montenegro's Vladimir Gojkovic scored with 46 seconds remaining to make it a one-goal game.
Bailey is one of the first two male athletes (along with Azevedo) in USA water polo history to compete in four Olympics. UCI alum Jeff Powers is making his third appearance in the Olympics and Hutten his second. They were members of the 2008 U.S. squad that won silver in Beijing.
