English batsman Jos Buttler continued his red-hot form with a 94 not out as Rajasthan Royals thumped Mumbai Indians by seven wickets here on Sunday to boost their chance of qualifying for the Indian Premier League (IPL) play-offs.

After Mumbai posted 168/6, thanks to opening batsmen Suryakumar Yadav (60) and Evin Lewis, Buttler registered his fifth consecutive fifty, which contained five sixes and nine fours, to guide his team to seven-wicket victory with two overs to spare.

The loss left three-time champions Mumbai stranded at 10 points from 12 games, while Rajasthan took their tally to 12 after 12 games.

The Jaipur-based outfit needs to win its remaining two games to qualify for the play-offs, while Mumbai's fate is not in their hands and will have to depend on the performances of other teams.

The result at the Wankhede Stadium was decisive since the winner not only bagged two valuable points, but also derail the loser's challenge for the race to the knockouts.

Asked to bat first, Mumbai were off to a steady start with Evin Lewis and Suryakumar coming up with an opening partnership of 87 runs off 64 balls.

Lewis, who narrowly survived being caught by Stuart Binny in the third over, made good use of the reprieve to blast his way to 60 runs off 42 deliveries. His quick-fire knock included four boundaries and as many.
