Sehrawat scored 10 raid points for the Bulls as the defending champions produced a composed performance to clinch the fourth place in the points table and improve their chances of qualifying for their playoffs.
U Mumba did have moments in the match when they looked capable of staging a comeback, but unfortunately they fell short by two points in a tightly contested affair.
The first half was evenly contested as expected, with both teams opting a rather cautious approach due to the implications of a bad result on their playoff chances.
Both teams were also hampered by injuries with Rohit Kumar absent from the Bulls' lineup and young Arjun Deshwal missing from U Mumba's raiding department.
The Mumbai defence took an offensive approach against Bulls' standby captain and chief raider Sehrawat and sent him to the dugout multiple times in the early minutes.
But the Mumbai side could not take advantage due to the lack of quality raiders in their ranks. And that eventually came to haunt them in the final minute of the first half when Sehrawat secured a Super Raid in a five-point move that secured the Bulls an All-Out and helped them pull clear of U Mumba.
The first half ended 17-11 with the Bulls on top. The All-Out certainly pumped up the defending champions as they started the second half on a high.
Sehrawat continued his good work with the raids but it was the Bulls' defence, particularly Saraubh Nandal, who impressed as the Bulls inflicted another All-Out on U Mumbai in the 7th minute of the second half to open up a 12-point lead.
Nandal secured his High 5 as Bulls looked to sit on the lead. But cautious approaches seldom work in kabaddi, and U Mumba stormed their way back into the match through some direct raiding by Abhishek Singh and clinched an All-Out with five minutes left on the clock to make it a four-point game.
But the Bulls' defence held firm in the dying minutes to clinch an important victory.
