BEAVER CREEK, Colo. -- Lindsey Vonn remains on top of her game despite the turmoil in her life.

She dominated at Lake Louise last weekend, winning two World Cup downhills and a super-G by a combined margin of 3.82 seconds -- a landslide in skiing.

Her success comes in the midst of divorce proceedings from her husband of four years, Thomas Vonn, who also served as her adviser and personal coach.

But if the tumult is affecting her, Vonn certainly isn't showing it on the slopes.

ASPEN, Colo. -- After four years of marriage, Lindsey Vonn is splitting with Thomas Vonn, who also serves as her chief adviser and assists as a coach.

The Olympic gold medalist skier confirmed Sunday night the couple has started divorce proceedings.

HIGHLANDS RANCH, Colo. -- Lindsey Vonn has found her rhythm on the ski slopes and the dance floor.

The Olympic gold medalist turned in quite a two-step to start the season, capturing her first giant slalom race last month followed by attending her first homecoming dance with a teenager who gathered up enough courage to ask her out.

DENVER -- The custom-fitted helmet that Colorado Avalanche forward Peter Mueller will wear this season provides peace of mind as much as added protection.

He was so concerned about suffering yet another concussion, Mueller opted for an Easton model that cradles the base of his skull and safeguards the top of his temples.

Mueller, who missed all last season with a head injury, feels safe on the ice -- almost.

DAEGU, South Korea -- The world championships are supposed to offer a peek of what's in store for the 2012 London Olympics.

Yet some of the biggest names in U.S. track have been reduced to spectators.

Tyson Gay is out with a surgically repaired hip; Jeremy Wariner's sidelined with a torn ligament in his left foot; and Wallace Spearmon, along with hurdler Lolo Jones, didn't even make the team.

DENVER -- The piercing twinge Minnesota Twins reliever Glen Perkins experienced each time he threw to the plate almost felt like a knife being plunged into his ribcage -- and twisted.

What started as mild discomfort in his right side as he warmed up in the bullpen had exploded into full fury after a few pitches on the mound.

Finally, Perkins couldn't stand the agony and motioned to the dugout to be taken out of the game at Arizona in May.

COLORADO SPRINGS, Colo. -- There was a time when Yani Tseng shied away from socializing on the golf course.

Usually outgoing, the top-ranked Taiwanese golfer was so insecure about her broken English that she would stay away from others in her group at LPGA events, rather than even attempt a conversation.
