The Boston Celtics are back in control of the NBA Finals, now just two wins from championship No. 18 . The Celtics blew an 18-point advantage, but quickly responded after the Warriors took a brief lead midway through the third quarter. And a 9-2 run to open the fourth gave Boston the separation that eventually led to a comfortable victory. Jaylen Brown (27), Jayson Tatum (26) and Marcus Smart (24) combined for 77 points, and it was Golden State that had the bigger turnover problem on this night.
