Sharapova, currently sidelined with a forearm injury, hasn't competed since losing to Serena Williams in the quarterfinals of the Australian Open in January.<br /><br />------------------------------------------<br /><br />Subscribe to our channel: http://read.ht/fLZ<br /><br />Follow us on Twitter: https://twitter.com/htTweets<br /><br />Like us on Facebook: https://www.facebook.com/hindustantimes<br /><br />Watch more videos at: http://www.hindustantimes.com/video<br /><br />hindustantimes.com © 2015
