Ireland's talented Maguire twins, Leona and Lisa, No 9 and No 16 in the women's world amateur rankings, have entered the St Rule Trophy -- a 54-hole tournament over St Andrews' Old and New Courses -- for the first time.
May 28-29 will be the first time the 16-year-olds, who both have a handicap +4, will have played the Old Course.
Leona won the Portuguese women's amateur championship earlier this year and would have won the recent Helen Holm Scottish women's amateur stroke-play championship but for taking three putts from six feet on Royal Troon's 18th green and finishing one shot behind the winner. Lisa won the Spanish women's amateur title this year.
David Haye claims Wladimir Klitschko would need a chin transplant to save him from being "destroyed" in their July 2 clash.
The WBA heavyweight champion will take on his IBF, IBO and WBO counterpart in a unification fight at Hamburg's Imtech Arena and believes all he needs to win is "a referee who can count to 10".
"I looked into (Klitschko's) eyes for 20 minutes and visualised me destroying him," said Hayes. "I looked into his eyes and saw him beaten and broken. He's never fought anyone with my attributes, it's new territory for me and for him.
"He'll do what he always does. I've fought these 'robots' before -- I've never lost, at amateur or professional level, to an Eastern European fighter and that's not going to change now."
Wales coach Warren Gatland has summoned Gavin Henson from the international wilderness and urged him to grasp his World Cup chance. Henson, who last played for Wales during the 2009 Six Nations, features among a 26-man squad from which Gatland will select his team to tackle the Barbarians in Cardiff on June 4.
His call-up comes after the Toulon centre was suspended by his club while they investigated an altercation involving the 29-year-old and team-mates last month.
But Henson then gained a second chance, being restored to Toulon's squad and appearing as a sub against Montpellier on Saturday.
Gatland said: "This game gives us an opportunity to get Gavin back into the fold. He hasn't been involved for a while, and we want to have a look at a quality player.
Andy Roddick continued his poor start to the clay-court season, as he was beaten 6-3 6-3 by Gilles Simon in the opening round of the Rome Masters. The 28-year-old former No 1 also lost to qualifier Flavio Cipolla in the first round of last week's Madrid Open.
Andy Murray, beaten by Thomaz Bellucci in the third round of last week's Madrid Open, has a bye into the second round where he faces Belgium's Xavier Malisse.
