Tiger Woods says that his mother, Kultida, has died at age 80. The golfer credited her for his success and encouraging his signature look of red shirts on Sunday.

Kultida Woods, the Thai-born mother of Tiger Woods who instilled his dominant spirit and encouraged him to wear a red shirt on Sunday as his power color, died Tuesday. Woods announced the death of his 80-year-old mother in a social media post.

A mark of the impact Kultida Woods forged on the record-breaking career of her son, Tiger, was provided by the fact the US President led the tributes after the 80-year-old unexpectedly died on Tuesday morning.
