Cut top and bottom off squash. Slice crosswise into 1/2inch thick slices. Use a cookie cutter to cut out center seeds. Arrange squash in baking dish. Combine remaining ingredients in a small saucepan and heat until bubbly; pour over squash. Bake, basting occasionally, until tender, 30 minutes.
If squash needs browning, turn up heat in broiler; broil until lightly glazed.
