TRADES: A person familiar with the deal says the Los Angeles Lakers have traded point guard Steve Blake to the Golden State Warriors for reserve guards Kent Bazemore and MarShon Brooks.
The person spoke on condition of anonymity to The Associated Press on Wednesday night because the trade was still pending NBA approval. The Los Angeles Times first reported Blake had been traded.
• The Brooklyn Nets acquired guard Marcus Thornton from the Sacramento Kings for Jason Terry and Reggie Evans on Wednesday, removing two little-used veterans from their aging roster and hoping a younger one can rediscover his scoring touch.
KNICKS: Amare Stoudemire sat out the Knicks’ game Wednesday night against the New Orleans Pelicans.
Knicks coach Mike Woodson says Stoudemire’s left knee was sore following Tuesday night’s 98-93 loss at Memphis. Woodson says trainers have indicated Stoudemire has no new injury of any significance.
Stoudemire has played in 40 of New York’s previous 53 games this season, averaging 10.2 points and 4.5 rebounds in 19.7 minutes per game. In late January, he missed seven games with a left ankle sprain.
