Sachin Tendulkar roared back to form ahead of the upcoming Test series against England with a strokeful 137, while Ajinkya Rahane remained unbeaten on 105 to help Mumbai pile up 344 for four against Railways on the opening day of their four-day Ranji Trophy match in Mumbai on Friday.

Tendulkar, in Mumbai colours after three years, came in at no 5 and batted fluently after starting cautiously against a largely inexperienced Railways attack to reach his hundred off 103 balls with 14 fours and 3 sixes. In all, the senior India batsman, whose last hundred in any form of the game was his unprecedented and much-feted 100th international century at Dhaka on March 16, struck 21 fours and three sixes during his 136-ball knock before edging medium pacer Anureet Singh to the slip cordon, three overs before stumps.
