The NBA Roundup …

AUBURN HILLS, Mich. — Chauncey Billups scored 24 points and Antonio McDyess added 18 in just 20 minutes to help the Detroit Pistons hand the Boston Celtics their 15th straight loss, 109-102 on Tuesday night.

The Celtics, who extended the worst losing streak in franchise history, haven’t won since a 128-119 victory in Memphis on Jan. 5. They have allowed at least 100 points in five straight games.

Boston also had to send forward Paul Pierce home with an infected left elbow. Pierce, who has missed Boston’s last 23 games with a foot injury, is expected to be hospitalized for at least two days, which will push his possible return back past the All-Star break.

Ryan Gomes led Boston with 19 points, despite only playing four minutes in the second half.

Knicks 102, Clippers 90

NEW YORK — Stephon Marbury scored 12 of his 15 points in an early second-half run that overwhelmed the Clippers and turned the game around for New York.

Jamal Crawford and Eddy Curry each scored 23 points to lead New York, which shot poorly and defended worse in the first two quarters before controlling the second half of its second consecutive victory.

Elton Brand had 22 points and 13 rebounds for the Clippers, who lost for the third time in 10 games.

Rockets 98, Grizzlies 90

MEMPHIS, Tenn. — Tracy McGrady scored 33 points and had eight assists to lead the Rockets over the Grizzlies.

Houston won for the sixth time in the last seven games.

Pau Gasol led Memphis with 30 points and 13 rebounds.

Bucks 116, Magic 111

MILWAUKEE — Ruben Patterson scored 14 of his 27 points in the fourth quarter and the struggling Milwaukee Bucks beat Orlando to snap a four-game losing streak.

The Bucks won their seventh straight at home against the Magic but have still lost 15 of their last 18 games overall without injured Michael Redd.
