Bumrah, Krunal Pandya star as Mumbai and Bengaluru win in IPL
India pace bowler Bumrah led five-time champions Mumbai to their fifth successive win with a 54-run hammering of LSG at the Wankhede Stadium.
In the second match of the day, Krunal's unbeaten 73 helped RCB beat Delhi Capitals by six wickets to move above Gujarat Titans at the summit.
Chasing 163 for victory, Bengaluru slipped to 26-3 before Virat Kohli and Pandya put together a fourth wicket partnership of 119.
Tim David smashed 19 not out off five deliveries to secure the win with nine balls to spare at Delhi's Feroz Shah Kotla ground.
"He (Pandya) can make that impact and we were just waiting for him to come into this tournament with the bat as well," Kohli said of player of the match Pandya, who also took 1-28 with his left-arm spin.
"And today was his day completely and he was absolutely brilliant."
Kohli compiled a measured 51, while Pandya struck five fours and four sixes in an innings which took the game away from Delhi.
It was Bengaluru's sixth successive away win as they and Kohli search for their first IPL title since the league's inception in 2008.
Bhuvneshwar Kumar and fellow pace bowler Josh Hazlewood shared five wickets between them to restrict Delhi to 162-8.
In the chase, Delhi skipper Axar Patel opened the bowling with his left-arm spin and struck two early blows to send back England's IPL debutant Jacob Bethell, out for 12, and Devdutt Padikkal, for a duck, two balls later.
Bengaluru skipper Rajat Patidar was run out for six but Kohli and Pandya put Delhi under pressure with occasional boundaries mixed with quick running between the wickets.
Once set, Pandya unleashed his power and reached his fifty off 38 balls with a four off Axar.
Kohli completed his sixth half-century of the season as he edged past Mumbai Indians batter Suryakumar Yadav (427) as the leading run-scorer with 443.
He finally fell to Sri Lanka fast bowler Dushmantha Chameera before Pandya and Australian international David took the team over the line.
Jacks of all trades
In the first match, Mumbai posted 215-7 after South Africa's Ryan Rickleton hit 58 and Suryakumar Yadav hammered 54.
All the bowlers contributed, including England's Will Jacks who took two wickets in one over, as Mumbai bowled out Lucknow for 161.
"I will always be a batter who bowls, my bowling is important," said player of the match Jacks, who also made 29 with the bat.
"I have worked hard on my bowling, doesn't matter what others say. There are still improvements to be made."
It was Mumbai's record-extending 150th IPL victory.
Bumrah dismissed Aiden Markram to go past former quick Lasith Malinga's record of 170 IPL wickets to become Mumbai's all-time leading bowler.
Bumrah, who recently returned from a back injury that forced him to miss India's Champions Trophy title win in Dubai last month, now has 174 IPL wickets.
Jacks got Nicholas Pooran out for 27 with his off-spin and struck two balls later to send back Lucknow skipper Rishabh Pant, caught out for four while attempting a reverse sweep.
New Zealand left-arm quick Trent Boult took down Australia's Mitchell Marsh for 34 and later dismissed Ayush Badoni for 35 to derail the chase, returning figures of 3-20.
