The Boston Celtics will look to run their winning streak to three ahead of one of their toughest tests of the season when they host the Detroit Pistons on Wednesday.The Celtics face the Pistons a night before traveling to Milwaukee to take on the NBA-best Bucks in the tail end of a back-to-back. Boston has cruised in its past two contests, wins over weaker clubs in the New Orleans Pelicans and Chicago Bulls.The Pistons also fit that mold, losing 12 of their past 15 games and still without several key starters due to injury. Detroit and Boston faced off earlier this year, the Celtics running away with a 114-93 win on Dec. 20.Boston has won six of the past seven meetings between the clubs.The Celtics have taken advantage of a softer part of their schedule to put a season-long three-game losing streak behind them. Jayson Tatum has led the way of late, following a career-best 41 points against the Pelicans with a team-high 21 in Monday’s 113-101 victory over the Bulls.”I think we’ve got a really good team, and any given night we’ve got guys that can go for a large amount of numbers,” said teammate Jaylen Brown, who scored 19 in the contest. “So, for us, continue to play the right way and let the game kind of tell you what to do, and I think we’ll be all right.”Tatum is probable for Wednesday’s game with right knee soreness, while big man Daniel Theis (right knee) is questionable after missing Monday’s win.Also excelling of late for Boston is guard Marcus Smart, who returned from a lengthy absence with an eye infection in late December. Smart had 12 points and eight assists and played a team-high 33 minutes against Chicago while finishing plus-25.”He’s been a great boost for us, and I think he’s starting to find himself after being out so long in these last three, four games,” coach Brad Stevens said.
