Rohit Sharma was all praise for paceman Jasprit Bumrah, who earned his maiden Test call-up for the upcoming South Africa tour. India will begin their tour of South Africa with a two-day warm-up match at Boland Park in Paarl from December 30-31. The first Test of the three-match series will get underway at Newlands from January 5.Rohit himself is all set to make his international captaincy debut when India host Sri Lanka in first of the three one day internationals in Dharamsala on Sunday. Rohit has led Mumbai Indians to three championships in the Indian Premier League and is the only captain to achieve the feat in the cash-rich T20 league.Rohit was named the 24th captain of India when Virat Kohli was rested for the ODI and three-match T20 International series against Sri Lanka.”It’s a great boost for him to be a part of the Test team. He was looking forward to it, he was for a while wanting to be a part of the Test team. It’s all the reward for what he has done in the ODI and T20 formats. Over the last year and so, how he has improved himself, on his bowling and fitness as well…it is a reward for all of those things and it shows. It’s a lesson for all those cricketers that if you put in all those hard yards, you will get the result…you will get rewarded. And Bumrah has actually been rewarded for the things that he has done in the past few years,” Rohit said on the eve of the first ODI.advertisementBumrah first came into the limelight in the Indian Premier League in 2013. Playing for Mumbai Indians, he picked up three wickets from two matches but was noticed for his slinging action. The following year, he played 11 matches and finished with five wickets but his death bowling made him a potent weapon for the Rohit-led team. The following year was also not that great in terms of wickets but he delivered when the captain needed him.Bumrah will once again spearhead India’s pace bowling attack alongside Bhuvneshwar Kumar when they face Sri Lanka in the first ODI on Sunday.”Yes! He has played with me at Mumbai Indians. Every game, every series we’ve played, he has come up with new strategies, new plans and it’s good to see that he has matured as a bowler. He understands what he needs to do and what the team expects out of him. And he is very focused guy, very disciplined in terms of his work ethic and that is what is giving him the results on the field. He had a good month-month and a half time off and he went to NCA and worked on his body again and rejuvenated and he looks a lot fresher now. And hopefully he can do the job for us, the way he was doing in the past,” the stand-in skipper added.Looking at this abilities, Bumrah was called up for the Australia tour Down Under and made his international debut during an ODI series in January 2016. He was impressive in his debut game and finished with 2/40 as India defeated the hosts by six wickets in the last match of the series.Impressed with his solid performances, the team management then handed the pacer his maiden T20I cap during the three-match series against Australia. He pocketed six wickets in three matches as India swept Australia aside in their own backyard.And he has not looked back ever since and only got better.He came back into the IPL and had his best two seasons in 2016 and 2017. In 2016, he picked up 15 wickets from 14 matches while this year, he starred for Mumbai in the championship winning campaign with 20 wickets from 16 games. Currently, the pacer has 46 wickets from 47 IPL matches.He recently became the second quickest Indian to bag 50 wickets in ODI and rose to No.3 spot in ICC rankings. He is also the No.1 bowler in T20 cricket.The 22-year-old now has 52 wickets from 28 ODIs and he has got 40 scalps from 30 T20Is.
