BOSTON -- Isaiah did it for Chyna.
On his late sister's birthday, Isaiah Thomas honored her memory with a career-high 53-point night in the Boston Celtics' 129-119 overtime victory over the Washington Wizards in Game 2 of the Eastern Conference semifinals on Tuesday.
Thomas lost his sister Chyna in a one-car accident in their home state of Washington on April 15. Every day since has been an uphill struggle for the 5-foot-9 superstar.
