Spoiler Alert

With just about a month left until the French Open, now's the time for players to really dig in and make a push for this year's grandest clay court title. And while many of the sport's biggest stars concentrating their efforts this week and some higher profile tournaments, some lesser known names have been quietly pulling off some mighty big wins elsewhere on the dirt.

A handful of top-twenty players made their way over to Bucharest, with world #10 Janko Tipsarevic leading the pack. Upsets rocked the draw from the start, though -- Germany's Daniel Brands, a surprise semifinalist in Doha, was up a set and a break when wildcard Gael Monfils retired, and one-time top-tenner Mikhail Youzhny dropped at the hands of Victor Hanescu in his opener. But a couple others had even better success.

Last year's giant killer Lukas Rosol hasn't had many high-profile wins since, but some time on the Challenger's circuit and two big wins for the Czechs during Davis Cup action has helped him crack the top fifty this year. Momentum is on his side in Romania too -- he took out third-seeded Andreas Seppi in the second round, and a win today over Viktor Troicki gave him entry into his first ever ATP semifinal. He'll be rewarded with a battle against the highest seed left, Gilles Simon, which will be no easy task, to be sure. But if he can pull it off he might have set himself up for some real successes the rest of the year.

Guillermo Garcia-Lopez has had a little more success over the years -- he beat Andy Murray last year at Indian Wells and has a couple Tour titles to his name -- but it's been a while since he's done anything too noteworthy. Before Bucharest he'd only won two main draw matches this year and, since peaking at #23 in the world about two years ago, he's since fallen to near triple-digit rankings. But this week the Spaniard seems to have found his game again -- he took out Horacio Zeballos, the most surprising man to beat Rafael Nadal this year and backed it up with a come-from-behind win today over Tipsarevic. He'll meet Florian Mayer next -- a man who's also been struggling to recapture recent glory -- so there's no reason he can't make a real play for title #3 here.

There's plenty of opportunity for the ladies to deliver similar results in Marrakech too. Top seeded Dominika Cibulkova pulled out after a long Fed Cup weekend and second seed Sorana Cirstea, largely pulling her career back in line after a breakout 2009 season, lost her opener in two quick sets. And that's allowed more than a few underdogs -- a couple of them veterans -- to pull through this week.

Chanelle Scheepers won her first and only title two years back in Guangzhou at the ripe "old" age of twenty-seven, but an unimpressive performance in 2012 send her out of the top fifty to end the year. She'd only won three Tour-level matches this year and most recently lost in the quarters of an ITF event in Pelham. The South African may have turned things around this week, though -- she dominated Cirstea in their opener and was similarly strong against rising French star Kristina Mladenovic earlier today. Her win set her up for a semifinal showdown against one-time Roland Garros champion Francesca Schiavone -- certainly no pushover, of course, but a big fight now could make everyone else sit up and take notice the rest of the season.

Thirty-two year old Lourdes Dominguez Lino has won two titles in her career, both in Bogotá, five years apart. She, not surprisingly, is something of a clay court specialist though, and lost every match she played this season before hitting the dirt. But she's finally hitting her stride in Morocco -- after defeating lucky seed Tsvetana Pironkova she took out defending champion Kiki Bertens in three tight sets. It'll be the Spaniard's first Tour semi in over two years, and maybe her best chance in a while to take home a title.

Her opponent on Saturday will be rising star Mandy Minella of Luxembourg, who first started grabbing headlines at the 2010 U.S. Open. She's won just a handful of main draw matches this year and has been hanging out just in the top hundred for a while. But a win over still-recovering Kaia Kanepi in the Marrakech second round was followed by a solid three-set win over Silvia Soler-Espinosa on Friday. She's lost the only match she's played against LDL, back in Bogotá 2011, and hasn't had too much of a challenge yet this week -- she'll have to raise her game even further if she wants to reach that elusive first career final.

All these guys and girls have put up some big wins over the past week, and while there's plenty of work left to do before taking home a title, their performances should show they're capable of doing some damage. This is the time of year, after all, when not even the biggest or most consistent stars are safe -- and any of these athletes could prove themselves to be the big spoiler this spring.

Keeping Focus Amid the Storm

If the theme for the first part of the week at the U.S. Open was the blazing heat, then the theme for the this weekend is the pending arrival of a hurricane named Earl, who promises to wreak havoc on the play today.

I'm keeping my fingers crossed, but some of the late night matches are clearly at risk -- if not for cancellation, then certainly for suspensions and delays. And that might give players like Rafael Nadal and John Isner, Venus Williams and Flavia Pennetta a few fits as they try to wrap up their day.

Pennetta's will be the last match on the Grandstand this afternoon, and she takes on Shahar Peer in what could be a very close game. The two have only played on hardcourts, with Peer -- ranked slightly higher at #19 to the Italian's #21 -- battling to victory in their last meeting at Indian Wells. A few months ago I might have chosen Flavia to power through this match easily -- if only for revenge -- but a foot injury that forced her out of New Haven puts her prospects in question. We know the girl can handle disruption, though, as she famously survived a meltdown by Vera Zvonareva at last year's Open. If she can find the power that got her past Jie Zheng in Cincinnati and Daniela Hantuchova in Montreal, I like her chances to win here too.

Big-hitting American John Isner should start his second-round match with Marco Chiudinelli before the rain starts, but if their five-setter at Roland Garros is any indication, he might not close it out in one shot. Isner certainly knows how to handle delays in a match -- the winner of the three-day Wimbledon marathon was able to keep himself loose and focused even through multiple over-night breaks. More comfortable in front of the hometown crowd, he might have the advantage over the Swiss, and hopefully this time his efforts will not be stopped short immediately after the initial win.

Venus headlines the night session on Arthur Ashe tonight, taking on her second qualifier in a row in Luxembourg's Mandy Minella -- a twenty-four year old who ousted Venus's foil Tsvetana Pironkova in the second round. You have to hand it to an unknown that can make it through three matches before even seeing a main draw and then continue her streak. And though Venus should be able to handle her easily, the two-time U.S. Open winner will have to remain focused on returning a solid serve and keeping up with an agressive baseliner. Battling injury herself, you can expect Williams to make a statement early -- she doesn't want to face the prospects of interrupting any momentum she gains by aggravating her knee any more.

Top-seeded Rafael Nadal hopes to cap off the action Friday night on Ashe, but the coming rains are not his only obstacle. Uzbek Denis Istomin made the finals in New Haven last week with a win over a tough Viktor Troicki in the semis, and he took a set from Rafa back at Queen's Club. He had a solid win over Maximo Gonzalez in the first round of the Open and fired off six aces to his opponent's zero. Nadal, on the other hand, was pushed to two tiebreaks against a feisty Teimuraz Gabashvili Wednesday and might be less comfortable on the quick courts. Admittedly, I'm a little nervous about this match -- two years ago, Rafa was unable to come back during a rain-disrupted semi against Andy Murray and ended up losing the match over two days. Hopefully this year he'll be able to keep his cool and, if needed, return to the court even stronger.

It sure looks like we're in for a lot of stop-and-start play today, and that could surely play with the momentum and focus of even top players. But when the day is done, hopefully no one will be too bruised and battered, and we'll only see better play to come.
