NEW YORK -- The Boston Celtics hit the 50-win plateau for the first time in six seasons after recording a 110-94, wire-to-wire win over the New York Knicks on Sunday.

It is an achievement coach Brad Stevens, now in his fourth year, believed would take a little longer.

"A couple of years ago I would have thought that would be something we would have to build for a while for," Stevens said. "Obviously we have been lucky to strike on a couple of guys.

"Everyone has a like mind, trying to compete every night. We look forward to the playoffs, then we will look back to what we have accomplished this season."

The Celtics went 25-57 in 2013-14, Stevens' first season in Boston. Now they are contending for first place in the Eastern Conference.

The win enabled the Celtics (50-27) to maintain a half-game lead over the Cavaliers in the East. Cleveland topped the Indiana Pacers 135-130 in double overtime Sunday night.

The Celtics play at Cleveland on Wednesday. The Cavaliers are 2-1 against Boston this season.

The Celtics are tied with Golden State for the most wins (24) since Jan. 25.

Al Horford is one of the guys Stevens referred to after the game. The veteran center, acquired from the Atlanta Hawks, scored 14 points and grabbed seven rebounds, hitting on his season averages.

"I've been proud of the way that our guys have all gotten better as the year has gone by," Horford said. "I think it's a special thing. Not a lot of teams get to win 50-plus wins in a season and now we have to build on it."

The Knicks (29-48) lost their 11th game this season by a margin of 15 points or more.

The blowout allowed Stevens to rest his starters in the fourth quarter, including Isaiah Thomas, who led the Celtics with 19 points and six assists in just 23 minutes. Jaylen Brown, filling in for Avery Bradley, scored 16 points. .

"I think we're in pretty good shape from a legs standpoint," Stevens said. "There may be a point or two in the next 10 days where we sit guys a little more, but right now we're focused on playing good basketball."

Courtney Lee paced the Knicks with 16 points and Kristaps Porzingis had 14, but had only one rebound. Carmelo Anthony sat out with back soreness.

Marcus Smart's 3-pointer started a 10-0 run to begin the fourth quarter, giving the Celtics their largest lead, 98-71, to that point.

Boston built an 88-71 lead going into the fourth quarter.

The Celtics missed three straight 3-pointers towards the end of the first half but still maintained a 60-47 lead at the break. Boston led by as much as 60-41, but the Knicks ended the second quarter with a 6-0 run.

A layup from Thomas capped a 7-0 run, giving Boston a 20-9 lead. He scored 10 points in the first quarter, helping Boston take a 34-23 advantage.

"We were trying to run early offense," said Knicks coach Jeff Hornacek. "We didn't execute quick enough."
