Chennai Super Kings made it 12 wins in the past 15 Indian Premier League meetings with Rajasthan Royals as they eased to a 45-run triumph on Monday.
Moeen Ali contributed with both bat and ball as the Super Kings proved far too strong for their opponents at the Wankhede Stadium.
The Royals had prevailed in four of their previous five games at the Mumbai ground - including last time out against Delhi Capitals in a thriller - but fell away badly in reply to Chennai's total of 188-9.
Jos Buttler provided the only innings of note from the top order in the run chase, making 49 from 35 deliveries with five fours and a pair of sixes.
Rajasthan were in contention at 87-2 in their reply, but Buttler's departure - bowled by Ravindra Jadeja - sparked a collapse that saw five wickets fall for eight runs. They finished up on 143-9.
Jadeja finished with 2-28 but fellow spinner Moeen was the pick of the attack, the England all-rounder taking 3-7 from his three overs having earlier made 26 in Chennai's innings.
Faf du Plessis top-scored with 33 as all the top five reached double figures, while the Super Kings demonstrated their strength in depth when Dwayne Bravo made 20 not out from number nine in the order.
Royals run into trouble
Despite a miserable overall record, Rajasthan had won back-to-back matches against Chennai. However, they were unable to equal their longest winning run against them.
Buttler did his best but there was little support from the rest of the top order, the Super Kings' spinners emphatically turning the game in their favour.
All-round balance helps Chennai
Moeen Ali is the only player to reach three figures for runs and also claim a wicket so far in the 2021 IPL season.
His signing by the Super Kings in the auction appears an astute piece of business, particularly as the left-handed batsman has capitalised on his opportunities to bat up the order.
