Boston at Chicago

Boston came through with its best defensive performance of the series in its 104-87 win in Game 3, holding the Bulls to 39.3 percent shooting and 6-of-21 from three-point range. Isaiah Thomas scored 16 points as he rushed back from attending his sister's funeral, and the whole Celtics team played an inspired effort.  Five of the last seven meetings have now gone UNDER and the Bulls have gone UNDER six of their last eight games overall as their late-season defensive improvement got them into the playoffs. Also, Chicago is 39-18 UNDER after an ATS loss and 23-10 following any loss and 20-8 UNDER after a loss of 10-plus points. Rajon Rondo is also out with a thumb injury. Play the UNDER in the first half and for the full game.
