Dwyane Wade will become a free agent Wednesday, and his 12-year stay with the Miami Heat could be ending.

The three-time champion and 11-time All-Star announced his decision Monday through a spokesperson. ESPN was first informed of the decision. Wade could have exercised an option to earn $16.1 million with the Heat next season. Instead he decided to roll the dice and test his worth on the open market.

“We want Dwyane back,” Heat President Pat Riley said last week. “There’s no doubt about that.”

The Los Angeles Lakers and New York Knicks are both expected to pursue Wade. Wade said after the season that he wants to stay in Miami.

Deng decides to remain with Heat

Luol Deng has elected to stay with the Miami Heat next season, using his opt-in clause on a $10.1 million deal. The decision means Miami is basically set at small forward. Deng will be the presumed starter, with fellow former Duke star Justise Winslow — this year’s first-round Heat draft pick — and James Ennis backing him up.

• The Golden State Warriors have begun the process of keeping their championship roster intact. The Warriors exercised their $3.8 million option on reserve big man Marreese Speights for next season. The announcement brings back a key member of the NBA champions’ second unit.

Oosterhuis has Alzheimer’s

Former British golfer and CBS analyst Peter Oosterhuis says he has early onset Alzheimer’s disease.

The 67-year-old Oosterhuis went public with the news in Golf World’s digital magazine with hopes it can bring attention and raise money toward finding a cure.

Oosterhuis is a six-time Ryder Cup player from England who became part of the golf broadcast team for CBS Sports. He announced in January he was stepping away from television work.

 

Olympics

Details of Boston’s ’24 bid unveiled

The group trying to bring the 2024 Olympics to Boston released the most detailed look yet at its bid for the Summer Games on Monday, unveiling a $4.6 billion plan it says would create jobs and housing, expand the tax base and leave behind an improved city with a $210 million surplus.

The announcement was designed to answer critics who say the privately funded Boston 2024 has withheld details of the bid to prevent the public from assessing whether the games could be staged, as promised, without the need for taxpayer money.

But local Olympics opponents said the latest version of the plan still fails to guarantee taxpayers won’t foot the bill in the event of cost overruns or revenue shortfalls.
