AUBURN HILLS. Mich. -- Al Horford got the winning basket, though it was Marcus Smart who made the biggest play.With the game tied at 92, Jae Crowder missed a go-ahead 3-pointer, but Smart came from the corner to tip the ball back at the basket. His shot didnt go in, but it gave Horford time to set himself for the follow shot with 1.3 seconds left that gave the Boston Celtics a 94-92 victory over the Detroit Pistons.The credit goes to Marcus, because that was a championship-level play, Horford said. He crashed the glass hard.Said Pistons coach Stan Van Gundy: We just stood there and watched. They missed and no one moved or blocked out.Isaiah Thomas had 24 points and eight assists for Boston, while Horford added 18 points and 11 rebounds.We didnt call a timeout in the last four minutes, because I just wanted to let them play, Boston coach Brad Stevens said. Our guys were making the right reads and the right plays.Marcus Morris led Detroit with 24 points and Andre Drummond had 20 points and 17 rebounds. The Pistons became the last NBA team to lose at home.The teams traded the lead for most of the fourth quarter, and Kentavious Caldwell Popes 3-pointer -- his first basket of the game -- gave the Pistons an 87-86 lead with 1:54 left. The teams traded dunks, and Thomas hit a layup over Drummond with 1:10 to play to make it 90-89.Caldwell-Pope missed an open 3, making him 1 for 7 on the night, and Drummond fouled Thomas on another drive. He made both free throws with 30.5 seconds left to give the Celtics a three-point lead, but Tobias Harris hit a tying 3-pointer.We were in position to come out of here with a victory, but we let them get off two extra shots, Harris said. Nobody, including myself, turned around to keep someone off the glass.Boston, realizing that Drummond was on the bench, didnt call a timeout and it ended up being the difference in the game.Im kicking myself right now, because if we have Andre on the floor, we get that rebound and were in overtime, Van Gundy said. We had Aron on the floor to run the play that led to our 3-pointer, but when they didnt call a timeout, we couldnt get Andre back out there.The Celtics were 6 of 10 on 3-pointers in the first quarter, including Thomas buzzer-beater, to take a 30-23 lead. Boston led 50-47 at halftime.Detroit got 37 points from its starting frontcourt in the half, but guards Ish Smith and Caldwell-Pope had three points on 1-of-5 shooting. Bostons backcourt of Avery Bradley and Thomas combined for 18 points and nine assists.The Pistons used a 10-0 run to take the lead midway through the third quarter, and still had a 73-71 advantage at quarters end.TIP-INSCeltics: Thomas started the second half with a four-point possession. He hit a free throw after the Pistons were called for a defensive three-second violation, then knocked down his second 3-pointer of the game.Pistons: Stanley Johnson, normally one of the Detroits top bench players, didnt play. Van Gundy said that Johnson will only be used as a backup small forward, and he wasnt needed with Morris and Harris both playing well.DRUMMOND MILESTONEDrummond pulled down his 4,000th career rebound in the third quarter. At 23 years and 101 days, he is the second-youngest player to reach the milestone, trailing only Dwight Howard (22 years, 129 days).CELTICS PLAY SMALLStevens wanted to keep a smaller lineup on the floor to try to give Drummond and Baynes matchup problems. Smart played 30:36 while starter Amir Johnson only got 20:22. We were trying to stretch those guys as much as we could, he said. It is hard to do that, because of Morris and Harris, but we thought it went well.UP NEXTCeltics: Travel to Minneapolis to play the Minnesota Timberwolves on Monday.Pistons: Host the Houston Rockets on Monday.

Stephen Myler kicked six penalties as Northampton inflicted an 18-17 Aviva Premiership defeat on Worcester in a poor game at Sixways.The outside half was successful with six out of seven kicks, with severe ill-discipline costing the home side, who for much of the game were the more creative side.They scored two tries through Dean Hammond and Bryce Heem with Jamie Shilcock converting both and adding a penalty.Prior to the game, Northampton needed only a single try for their 1,000th in the Premiership but they never looked like achieving it.Ben Foden made his 200th appearance for Saints but they started badly as Shillcock kicked a penalty to give Worcester a third-minute lead.Northampton soon replied with a simple Myler penalty before the hosts scored an excellent try.From a ruck inside the opposition 22, Worcester secured possession for Shillcock to send Wynand Olivier through a gap before the centre gave Hammond a simple run-in.The visitors suffered two further setbacks in quick succession when skipper Sam Dickinson was helped off with a leg injury to be replaced by Ben Nutley. Myler was then surprisingly off-target with a straightforward penalty attempt.The night got worse for Saints when experienced scrum-half Lee Dickson left the field with a rib injury as Worcester continued to the be the better side.However, Warriors kept conceding penalties, nine in the first half-hour, which prevented them from capitalising and this allowed a disjointed Northampton to remain in contention.The 10th and 12th penalties saw Myler succeed with two kicks at goal so his side only trailed 10-9 at the end of a first half during which they had been largely outplayed.ddddddddddddThe home sides ill-discipline continued after the restart and after Ryan Mills was yellow carded, Myler put Saints in front with his fourth penalty after 45 minutes.With Mills still absent, Myler extended the lead with a further penalty but that was all Saints could manage while the centre was in the sin-bin.Worcester brought on Heem for his first game of the season in place of Cooper Vuna with lock Donncha OCallaghan also withdrawn in favour of Andrew Kitchener.Back to 15 men, Worcester regained control and were denied a try by the TMO after a burst from Olivier had put the Saints defence on the back foot.As a result, Northampton still led 15-10 at the end of the third quarter but their line was under constant pressure.In an attempt to stem the tide, they made three substitutions bringing on James Craig, Ethan Waller and Tom Collins to provide fresh legs and it paid dividends as Saints secured some respite with a sixth penalty from Myler.However there was a dramatic finish for when Heem finished off a flowing movement to score, Callum Clark was sin-binned for foul play after the award of the try.Shillcock converted from the touchline and then with the last kick of match he had a penalty from half-way to win the match but his effort faded wide.
