Is it bad for the game? Has she passed her peak and will never win a slam again? Should she retire? Where does she go from here? All questions arising after the Li match fiasco.
She certainly has been beaten with ease a lot in her career, odd for a player of her caliver. Is she the multiple slam winner that has recieved more beatdowns in slams?
AO 2013 SF vs Li 26 26
AO 2012 F vs Aza 36 06
AO 2011 4r vs Petko 26 36
AO 2007 F vs Sarin 16 26
RG 2009 QF vs Pome 26 06
RG 2007 SF vs Ajde 26 16
Wimby 2008 2r vs Alla 26 46
Wimby 2007 4r vs Vee 16 36
In 6 of those defeats she was inside the top 4.
To be fair, this list is not a good indication to prove Sharapova 's impotence in Slams. If you care to look in the circumstance, many of her defeats are understandable. Nothing to be ashamed of.
Before her injury after the AO 08, Maria wasn't that good on clay as she was learning how to play on clay, hence the lose to Ana who was at her peak around 07-08. That leaves her only 2 defeats pre AO08 were to the hands of Venus at Wimby 07 ( Venus still plays GOAT on grass on 07-08) and Serena on her favorite surface ( Aussie in the 00s). So Maria only lost to players at their respective peak forms, but she herself is very consistent to perform at top level. Look at where Venus and Ana are now.
After AO08, Maria was playing error prone tennis and she didn't return to the top 10 or reaching top form until she stopped making too many errors in matches and made the SF at RG11 and F at Wimbly11. That marked the point where she was not losing to scrubs any more, only to top players who in their GOAT forms. So those matches against Alla, Pome, Petko were in the period that she was recovering to top form where she also lost to Kimiko and Caro. Once she got back to the top, Maria only lost to players who at their peaks aka Vika and Li at the Aussie.
In conclusion, Sharapova is one of the top players who is consistently contend for Slams to the last stages. If she runs into another player in GOAT form, she would lose which won't happen often b/c besides Serena, current players play GOAT once in a blue moon. If she doesn't ( run into an in form top player), then she will compete for the Slam titles). So there's a good chance that she would win at least a Slam in the next 2 years, esp when she is playing well on all surfaces.
