Baynes gives Boston big inside presence

Aron Baynes is set to return to Boston's starting five for game four of their NBA eastern conference finals against Cleveland as the Celtics attempt to bounce back from a heavy defeat.

While Boston lead the best-of-seven series 2-1, the 30-point loss on Saturday has given the Cavaliers the momentum.

"I thought it was embarrassing," Celtics guard Jaylen Brown said of Boston's 116-86 loss and his own performance.

"I thought we came out, the way I played, the way I performed, how not aggressive I was in the first half."

Celtics coach Brad Stevens will want to make sure his youthful team makes a better start in Monday's game at Quicken Loans Arena.

Baynes starting at centre, in place of Marcus Morris, would stiffen Boston's inside game and free up fellow veteran Al Horford, who was kept to just seven points on Saturday.

The switch could force Cavs coach Tyronn Lue to make a counter move and put Kevin Love - or even LeBron James - on Boston All Star Horford.

"I think, as coaches, you probably watch it over and over and over and over, and then you try to just trim it to what's necessary," Stevens said.

"This team is, again, prideful, competitive. They've been resilient.

"Nobody felt good leaving the gym (Saturday) night. Nobody felt good when they woke up this morning.

"And so I think that we have to look at what we can do better; there is a physical component to that."

Baynes is Boston's biggest body and the 31-year-old adds some much-needed muscle.

Beyond any line-up tweaks, more concerning for Stevens may be his team's Jekyll-and-Hyde post-season play.

They have been sensational at home, going 9-0.

The road has been treacherous and the Celtics are 1-5, culminating in the weekend drubbing after they started the game lacking any intensity.

The good thing for Boston is that they don't have to win a road game to make the NBA Finals.
