India's ODI captain Mithali Raj on Thursday heaped praise on 15-year-old teen sensation Shafali Verma and said the aggressive opener can be a future star who can serve Indian cricket for a long time with proper grooming and exposure.

Shafali, who replaced the recently retired Mithali in the T20 squad, earned his maiden call-up for the ongoing T20 series against South Africa. Though India won the opening game in Surat, Shafali was dismissed for a duck.

Mithali was speaking after announcing the second Skechers Performance Mumbai Walkathon at a press conference here. The Marathon will be held on November 24 in suburban Malad.

She also said that she wants her ODI side to do well in the upcoming three-match ODI series against South Africa though it is not part of the ICC Championship. The ODI series, will be played after the ongoing five match T20 series.

Now that Mithali will be only playing one format, she feels that she has more time to work on her fitness.

"I have more time to work as a player on my skill on my fitness. I can give more importance to exclusively train on my strength and fitness sessions, which can help me come fresh for the ODI series," added Mithali.
