Calcutta/Mumbai: Mumbai teenager Pranav Dhanawade, on Tuesday, scripted history by becoming the first batsman ever to notch up a four-figure score, smashing an unbeaten knock of 1009 in an inter-school tournament, here.

The 15-year-old, playing for KC Gandhi Higher Secondary School, reached the gigantic score off just 323 deliveries with a jaw-dropping strike rate of 312.38 in the game against Arya Gurukul in the Bhandari Cup inter-school tournament organised by the Mumbai Cricket Association (MCA).

In the course of his awe-inspiring innings, which lasted 395 minutes, Pranav smashed a whopping 129 fours and 59 sixes. The epic knock ended when his school declared at 1465 for three at stumps on Day II, which is also a world record.

His school went past Victoria's 1107 against New South Wales made way back in 1926. Pranav now holds the record for the highest individual score in any form of cricket, bettering AEJ Collins's 628 not out for Clark's House against North Town in 1899 in the UK.

The 10th-standard boy is a ward of experienced MCA coach Mobin Sheikh and the only child of an autorickshaw driver.

Even the iconic Sachin Tendulkar congratulated Pranav for smashing those unbeaten 1000 runs. "Congrats #Pranav Dhanawade on being the first ever to score 1000 runs in an innings. Well done and work hard. You need to scale new peaks!," Tendulkar wrote on his twitter handle.

"Well played...no matter what levels cricket it is but numbers are just unbelievable.another @sachin_rt in making?" tweeted India off-spinner Harbhajan Singh.

India's limited-overs captain Mahendra Singh Dhoni also lavished praise on the lad. "Scoring 1009 runs is not a joke. It's a tremendous effort and shows a glimpse of talent. We need to nurture and guide him.

"It's important for those close to him to guide him in the right direction. He definitely has talent and it's important to see how he keeps improving as he will be competing against better opposition," he said.

Ajinkya Rahane also heaped praise on the fellow Mumbaikar. "I just want to congratulate him for scoring 1009 runs. It's a great effort.

"As a Mumbaikar, I am proud of him. He will do well for his school team and club. I'm sure he will work further on his game and come and play with us. I wish him good luck," Rahane said.

"This is a very big thing to bat for one-and-a-half days and needs immense concentration and focus," Rahane added.

On his part, Pranav said he had aimed to reach the four-figure mark after scoring a record 652 runs on Monday. "I couldn't believe it last evening that I had scored 652 runs. When I went home, I took a bath and slept and today, I set myself a target of 1000 runs," a cricket-specific website quoted him as saying.

Pranav's mammoth score was in reply to his rival team's paltry total of 31 all out in 17 overs, at the Vaylengar ground at Kalyan, in neighbouring Thane district. Pranav, who was unbeaten on 652 on Monday evening, had already became the world's highest-ever individual scorer in all forms of cricket.

During the course of his innings on Monday, he went past the highest individual score of 546 in Indian schools' cricket, which was held by another Mumbai cricketer, Prithvi Shaw of Rizvi Springfield, made against St Francis D'Assissi in the Harris Shield game back in 2013.

"Pranav is with me from the age of six. His feat would give a strong boost to cricket in this area. We have lot of talent in and around Kalyan, but lack of proper facilities has hampered it.

"Today, Dilip Vengsarkar came and promised an academy here if he is provided with the ground and our local MLA promised to provide him one wherever he wanted it," Sheikh said.

"It's a proper ground for an Under-16 game and the tournament is an MCA-recognised one. I was very happy with the opposing team, and the way they approached the game," added the 50-year-old, who has been an MCA coach for several years.
