Boston — Isaiah Thomas and the Boston Celtics have almost caught Cleveland for the top spot in Eastern Conference. Now they’re focused on passing the Cavaliers.

Thomas scored 30 points, including 20 in the second half, and Boston beat the Miami Heat, 112-108, on Sunday night for its fourth straight victory.

The win moved Boston within percentage points of Cleveland for the No. 1 seed in the East. The Celtics have one more victory than the Cavs, but also one more loss. Boston (48-26) also equaled its win total from last season.

Thomas said no one in a Celtics uniform was celebrating, though.

“It’s just a tie, though, so it’s not that cool,” he said. “Hopefully we can secure that spot and be No. 1. We’ve just got to control what we can control and take it game by game. We can’t really worry about what Cleveland’s doing or what other teams are doing.”

Jae Crowder added a season-high 25 points and six rebounds for the Celtics.

Rockets 137, Thunder 125

Houston — Lou Williams scored 31 points, James Harden finished with 22 points and 12 assists, and Houston cruised over Oklahoma City.

Oklahoma City star Russell Westbrook had 39 points, 11 rebounds and 13 assists for his second straight triple-double and his 36th this season, but Harden led the Rockets to a 25-point lead through three quarters in the matchup between top MVP candidates.

Bulls 109, Bucks 94

Milwaukee — Nikola Mirotic tied a season high with 28 points, Jimmy Butler had 20 points and a career-high 14 assists, and the Bulls pulled away for the win.

Butler broke his previous career best for assists (12) by the end of a pivotal third quarter, when Chicago stretched a one-point lead at the half to 91-79 going into the fourth.

Kings 98, Clippers 97

Los Angeles — Willie Cauley-Stein made a follow shot with two seconds left, lifting Sacramento to the road win.

Down 85-67 early in the fourth, the Kings rallied while Blake Griffin, Chris Paul and DeAndre Jordan were resting.
