Wozniacki can't see herself emulating Serena's journey

MIAMI - Caroline Wozniacki says it would be "impossible" for her to follow Serena Williams' lead and return to tennis after giving birth.

Williams, the 23-time Grand Slam champion, continues her comeback on Wednesday following the arrival of daughter Olympia when she takes on Japan's Naomi Osaka - winner of the Indian Wells title on Sunday - in the first round of the Miami Open.

Williams is certainly up for the challenge and is determined to roll back the years and return to the apex of tennis.
