Two-time Calder Cup champion Jay Henderson scored arguably his biggest goal as an Admiral, finding the net with 12:21 gone in overtime to give Milwaukee a 4-3 win in Cincinnati on Monday night.
The best-of-seven West Division semifinal series is now even at two games apiece.
Mike Farrell and Tony Hrkac recorded a goal and an assist each for the Admirals, who owned leads of 2-0 and 3-2 in the contest. Farrell set up the winning goal by Henderson, a member of Cup-winning teams in Providence (1999) and Houston (2003).
Milwaukee was 2-for-4 on the power play, and is now 9-for-28 in the series. Game 5 is Wednesday night in Cincinnati.
