MALE TENNIS, St. Rogers marches on in Hamburg

Fed marches on in Hamburg

Roger Federer will face Florian Mayer in the quarter-
finals of the German Tennis Championships after a
6-4 6-3 win over Jan Hajek. Federer, the top seed at the Hamburg event, took
little over an hour to beat the Czech qualifier despite
squandering 10 of his 13 break points, including five
match points in the eighth game of the second set. The 17-time grand slam champion one is playing
with a new, larger racquet in a bid to end a slump
which saw him eliminated second round of
Wimbledon./ "I guess it's to a degree some more getting used to,
just to see how it reacts on every single shot," he told
the ATP's official website. "Clearly it reacts better to some shots. But it's
important not to think of it the whole time, not to talk
about it all the time, but more just sort of go with it,
fight for every point, have the right mindset, be
optimistic about playing here now and wanting to
achieve a good result and that's what I'm doing." Home hope Mayer defeated 11th seed Feliciano
Lopez 7-6 (7-1) 6-2 to line up a meeting with
Federer. Second seed Tommy Haas also progressed on home
soil as he defeated Carlos Berlocq 6-2 6-4 to set up a
quarter-final with Fabio Fognini, who moved into the
last eight with a 6-2 6-4 win over Marcel Granollers. Wimbledon semi-finalist and fourth seed Jerzy
Janowicz had a bad day as he was forced to retire
from his match against Fernando Verdasco due to a
right arm injury when the Spaniard was leading 7-5
4-0. Verdasco will face qualifier Federico Delbonis in the
last eight after the Argentinian defeated Dmitry
Tursunov 6-4 6-3. Elsewhere, third seed Nicolas Almagro eased into the
quarter-finals with a 6-2 6-3 win over Guillermo
Garcia-Lopez. He will play fifth seed Juan Monaco,
who needed three sets to beat Benoit Paire 6-3 2-6
6-2.

BOXING, Chisora: My Mother knows best

Dereck Chisora has revealed how harsh words from

his mother convinced him to clean up his act. The controversial heavyweight will attempt to get his
career back on track when he faces American Malik
Scott at Wembley Arena on Saturday night. Chisora's reputation has been blighted by wild antics
such as the slap he aimed at Vitali Klitschko at a
weigh-in and his press conference brawl with David
Haye. But the Londoner decided to change his ways after a
stern lecture from mother Viola and an emotional
conversation with promoter Frank Warren. Chisora has undergone anger management sessions
and displayed an improved physique as he tipped
the scales at 17st 4lbs for the Scott fight. "One day my mother had had enough and she said
'why can't you just listen to me for once in your
life?'," he said. "She told me what to do and I thought I'll do it for six
months and if it doesn't work out I'll do it my own
way. So it was my mother who made me change, she
said I needed to start listening to people. "Then Frank got me in his office and had a go at me
in front of my mum and trainer. Frank said 'I don't
understand' and I saw tears in his ears. "Me and Frank have come a long way and I thought,
'you know what, I'll listen'." Chisora cannot afford another setback after suffering
four defeats in his last six fights, including a
stoppage loss to Haye last July. The 29-year-old failed to impress when he returned
with a win over little known Hector Alfredo Avila in
April, prompting Warren to read him the riot act. "He looked like a load of blubber. He'd been going
down the gym and coming home and having a pie.
You and I can do that, but not him," Warren said. "I just sat down him and told him straight - you can't
live like that and have the career you should have. He
has a lot of talent but was letting himself down. "I got in Viola's ear about it and she got on to him as
well. We both let him know that he could be doing
things better and it looks like he got the message. He
looks fantastic right now."

FEMALE TENNIS: Serena surges into semis

Serena surges into semis

Serena Williams dropped just two games as she
strolled into the semi-finals of the Swedish Open in
Bastad on Friday. The world No 1 broke her 54th ranked Spanish
opponent Lourdes Dominguez Lino three times in
each set to ease through 6-1 6-1. The American remains unbeaten on clay this season
after winning 26 straight matches, including a perfect
run on the way to her second French Open title and
16th Grand Slam singles crown. She will next meet Klara Zakopalova in the last four
after the third seed from the Czech Republic defeated
Dutch hope Richel Hogenkamp 6-2 6-3. Meanwhile, home favourite Johanna Larsson reached
the last four as she eased to a comfortable 6-1 6-2
victory against last year's finalist Mathilde Johansson
from France. The 2011 runner-up from Sweden will next take on
Italy's Flavia Penneta for a place in the final after she
overcame Frenchwoman Virginie Razzanno 6-1 6-3.
