Cleveland can complete its sweep of Boston on Sunday with another win, following Thursday's 103-95 victory in Game 3. Cavaliers star LeBron James led with 31 points and 11 rebounds, and forward Kevin Love added 23 points and nine rebounds. For Love, the win continued the hot streak he's been on since the start of the playoffs.

"Kevin has been great," said Cavaliers coach David Blatt, according to ESPN. "Maybe he didn't score as much in the second game as he did tonight, or in the first game, but he's been engaged at both ends (of the court)."

Cleveland has the chance to close out the series and earn a couple days extra rest, and Blatt insisted his team won't let off the throttle in Game 4.

"This is the playoffs," Blatt told the Cavaliers' official website. "We're playing a fine opponent, they are making it very difficult for us, challenging us, competing with us and we're doing what we have to win, but it's not coming easy and we're working very hard to be successful in this series."

Boston, meanwhile, is looking to extend the series to five games.  Celtics guard Isaiah Thomas was limited to just five points, but forward Evan Turner stepped up with 19 points, eight rebounds and eight assists, and guard Avery Bradley added 18 points.

"We've got to play better basketball," said Celtics coach Brad Stevens. "I don't mean to sound that general and I'm sorry I do, but we've got to play better basketball ... on both ends."
