Serena Williams revealed she was moved to tears while Jack Nicklaus sent his congratulations after Tiger Woods secured his 15th major at the Masters.
Woods carded a final round of 70 to win by one shot on a dramatic final day at Augusta, clinching a fifth green jacket but his first since 2005.
The 43-year-old has endured injury issues in recent years, raising doubts over his future in the game, but he completed a remarkable comeback on Sunday, much to the delight of those at the venue and millions watching on at home.
Tennis star Williams - who has returned to the court after giving birth to her first child in September 2017 - was quick to send out a tweet congratulating her fellow American, admitting she was inspired by Woods' success.
"I am literally in tears watching Tiger Woods - this is Greatness like no other," she wrote on social media.
"Knowing all you have been through physically to come back and do what you just did today? Wow. Congrats a million times! I am so inspired thank you buddy."
Woods is now one closer to the record of 18 major wins held by Nicklaus, who believes the result will provide a huge boost for the sport.
Nicklaus tweeted: "A big "well done" from me to Tiger Woods! I am so happy for him and for the game of golf. This is just fantastic!!!"
