Kelly Olynyk scored a team-high 19 points and hauled in 10 rebounds in 28 minutes, but the Celtics  had their two-game win streak snapped in an 85-78 loss to the Rockets on Wednesday afternoon in NBA Summer League play in Orlando. Olynyk did commit five turnovers and seven personal fouls in the loss. Summer league rules allow players to commit an unlimited number of fouls.
The Rockets, who recently signed free agent center Dwight Howard , jumped out to a quick start, leading 24-17 after one quarter.
The Celtics responded by outscoring the Rockets 23-19 in the second period and cut Houston’s lead to 43-40 at the half. But the Celtics offense went cold again in the third as Boston scored just 16 points and trailed 67-56 entering the final quarter.
Trailing 81-73 with 1:38 left in the game, the Celtics made one final push, cutting the lead to three, 81-78, on a Lawrence Hill 3-pointer with 26.9 seconds remaining. But those would be the final points of the day for the Celtics, who finished the scheduled portion of summer league at 2-2. They will have Thursday off before a playoff game on Friday.
The Celtics, who entered the day in third place in the standings, earned two points in the loss by winning the second and fourth quarters. They have 14 points, tying them with the idle Heat for third place. The Heat play Thursday. The Celtics are likely to play in either the third-place or fifth-place game on Friday.
The Rockets are a perfect 3-0, with their final scheduled game set for Thursday. The Rockets are second in the standings now with 16 points after earning five on Wednesday. Oklahoma City leads the group with 20 points after earning six on Wednesday in a win over the 76ers.
Tim Abromaitis (14) and Courtney Fells (10) were the only other Celtics scoring in double figures. Phil Pressey got the start again at point guard for the Celtics. He had an up-and-down game, dishing out a game-high 10 assists but committing four turnovers and making just 2-of-9 field goal attempts.
At halftime, new Celtics coach Brad Stevens  spoke to NBA TV. Stevens said he’s not worried about next season’s record as much as he is about the overall approach his new team takes to playing.
“I’ve been a lot less concerned about results [this summer] than playing to a standard. That’s going to be a major emphasis,” Stevens told Nick Cellini and Kendall Gill.
Stevens was also asked about Rajon Rondo  and whether he’s reached out to his All-Star point guard.
“From everything I’ve been told, his rehab has been going well,” Stevens said. “Shared quite a few texts, talked on phone. Will talk to him soon.”
