He was well-supported by opener Wasim Jaffer (137 not out), who scored his second consecutive century today, having hit 171 against Gujarat in their last league game.
Tendulkar and Jaffer lifted Mumbai from 35 for two at one stage to a 270-plus total by the end of day's play, after putting on a 234-run stand for the third wicket.
Tendulkar, who recently retired from One-Day International cricket, looked in sublime form as he notched up his 18th Ranji century.
From word go, the veteran was playing his shots. He hit a six off Ketul Patel to bring up the fifty, while his century came off an Ambati Rayudu over as he ran hard for two runs.
Playing his 35th Ranji match for Mumbai, Tendulkar spent 296 minutes at the crease for a well-made 108 that came off 233 balls, and was studded with 10 hits to the fence and a six. He was castled by Baroda pacer Murtuza Vahora, four overs prior to the end of day's play.
This was Tendulkar's second ton of the season. He had hit 137 against Railways in a league match in November last year.
He is now one short of the Indian record held by Sunil Gavaskar, who has 81 first-class hundreds to his name. In Ranji Trophy, Gavaskar had scored 20 centuries. (MORE)
