As Tiger Woods won the Masters on Sunday, plenty of WTA stars were watching - and hailing his comeback from repeated and serious back surgeries to reach the top of his sport once more.

Serena Williams - who has herself recovered from health issues as she aims to win a 24th singles Slam title - described Woods's achievement of a 15 major title as an "inspiration".

Many others were simply in awe of what they were seeing.

And the legendary Pam Shriver pointed out that there had been plenty of impressive sporting comebacks in tennis too.
