Heat-Celtics Game 3 Betting Preview

Miami won Game 1 of this Eastern Conference finals series Tuesday night 118-107, but Boston evened things up with a 127-102 Game 2 romp Thursday night. The Celtics actually trailed Game 2 by double-digits early but used a 60-21 run to lead 70-45 at the half. Boston then never let the Heat get any closer than 17 points from there on its way to the victory. The Celtics shot 51 percent from the floor Thursday, hit 20/40 from 3-point land, and won the turnover battle 15-10. Also, Game 2 played over a total of 206 with plenty of time to spare. With Thursday’s win, Boston is now 9-4 SU, 8-4-1 ATS this postseason. With Thursday’s loss, Miami is now 9-4 SU and 8-5 ATS this postseason. The Heat finished two games ahead of the Celtics in the regular-season standings, but Boston took the season series from Miami two games to one. So the Celtics are now 3-2, both SU and ATS against the Heat this season. On the injury front Miami G Kyle Lowry, who’s missed the first two games of this series with a bad hamstring, is listed as questionable for Saturday night. Meanwhile, Boston G Marcus Smart and F Al Horford both missed Game 1 of this series, but both played Thursday night.

Heat at Celtics Game 3 Prediction

Boston is probably the better team in this match-up and should win this game. But the Celtics probably won’t shoot 20/40 from 3-point land again anytime soon. Meanwhile, Miami is tough, and we love Jimmy Butler. Plus, this series is due for a nail-biter. So while we won’t call for the outright upset here, we are taking the Heat plus the points.
