Bumrah Saved MI 133 Runs in One Season — No Other Bowler Comes Close
133 Runs Saved — 29% More Than Any Other Bowler
Jasprit Bumrah finished IPL 2025 with a total surplus of 133 across 284 balls (47 overs). His +3 Ecae placed him atop the bowling value leaderboard by a margin so wide the gap itself tells a story.
The #2 bowler, Kuldeep Yadav of Delhi Capitals, posted 103 on a +2 across 307 balls. Bumrah's lead: 30 runs, or 29%. In a format where single-digit run margins decide matches regularly, 30 runs of surplus separation between #1 and #2 is not a gap. It's a chasm.
The Death Economy That Defies the Format
Bumrah's headline economy reads 7. That number alone places him in rare air, with the league average sitting well above 8. But the death-overs split is where his value becomes structural.
At death (overs 16-20), Bumrah bowled 98 balls at a 7 economy. The league death economy in 2025 was 10. That's a 3 run-per-over saving every time Bumrah operates in the phase where runs are most expensive and most valuable. He took 11 wickets in that phase, more than half his season total of 19, while maintaining a 37% dot ball rate at death.
His middle-overs economy was even more absurd: 5 across 96 balls, against a league average of 9. That's a 4 run-per-over differential, the largest phase advantage of any bowler in any phase during the 2025 season. Even his powerplay economy of 8 across 90 balls sat below the league PP average of 9.
Put differently: across his death-overs workload, Bumrah saved approximately 55 runs compared to what a league-average death bowler would have conceded. In a tournament where typical first-innings totals cluster near 190, those saved runs alone equal nearly 29% of a typical innings.
16 Overs of Free Bowling
The 133 total surplus, divided by league-average T20 economy of roughly 9 runs per over, equals approximately 16 overs. Mumbai Indians effectively received 16 overs of "free" bowling, overs where Bumrah's output was so far below league average that MI's other bowlers could concede at above-average rates and the team would still break even.
That calculation matters because MI did rely on it. Their bowling attack is built around the assumption that Bumrah absorbs 8 to 10 overs of elite containment, allowing more volatile options to attack without the pressure of holding an economy line.
Phase Distribution: Elite Everywhere
Unlike many death-overs specialists who trade powerplay control for back-end dominance, Bumrah maintained elite numbers across all three phases in 2025. He bowled 90 balls in the powerplay, 96 in the middle, and 98 at the death, and his Ecae remained positive in every phase.
This versatility is what generates 284 balls of workload. Bowlers who only excel in one phase get 150 to 200 balls per season. Bumrah's ability to bowl anywhere, at any stage of an innings, means his per-ball value compounds across nearly 47 overs of work. Volume multiplied by rate equals the 133 surplus.
WAR: The Best Bowler in T20 Cricket
Bumrah's 0.69 raw WAR per match ranks first among all specialist bowlers in our model, with a regressed WAR/M of 0.62 across 243 career T20 matches. His bowling WAR per match of 0.69 is entirely bowling-derived, with zero batting contribution and pure bowling value.
Our 2026 projection pushes Bumrah to 0.93 WAR per match, the highest projected bowling value in the league. That projection carries high confidence with a declining trajectory due to age, but even post-regression, Bumrah's floor exceeds most bowlers' ceilings.
Among all players regardless of role, only Abhishek Sharma (0.68) and Sunil Narine (0.68) carry higher regressed WAR/M. For a pure bowler to rank in that company is extraordinary.
Peer Comparison
| Bowler | Ecae | Balls | Surplus | Raw Econ |
|---|---|---|---|---|
| Bumrah (MI) | +2.81 | 284 | 133 | 6.57 |
| Kuldeep Yadav (DC) | +2.02 | 307 | 103 | 6.98 |
| Varun Chakravarthy (KKR) | +1.50 | 300 | 75 | 7.50 |
| Noor Ahmad (CSK) | +1.43 | 302 | 72 | 7.71 |
| Narine (KKR) | +1.17 | 271 | 53 | 7.68 |
| Boult (MI) | +0.65 | 346 | 37 | 8.71 |
Varun Chakravarthy's 300 balls lead the league in workload among high-Ecae bowlers, but his +2 rate generates less total value than Bumrah's +3 over fewer balls. Rate matters more than volume when the rate differential is this extreme.
MI's 2026 Bowling Core
Mumbai retained every piece of their bowling engine. Bumrah, Boult (+1 Ecae, 346 balls), and Deepak Chahar (+1 Ecae) return as key components of the pace attack. Combined with Shardul Thakur and Corbin Bosch, MI assembled 5 pace bowling options for 2026.
The additions don't replace Bumrah's value (nothing can), but they reduce MI's dependence on him bowling maximum overs every match. With Suryakumar Yadav (+18 SRae, 427 balls) anchoring the middle order and Ryan Rickelton and Will Jacks providing firepower at the top, MI's 2026 roster is built to leverage Bumrah's bowling surplus into match-winning totals on both sides of the innings.
MI sit at Elo 1653, first in the league under the WAR-based model that initializes 2026 ratings from squad composition rather than franchise history. Bumrah's projected 0.93 WAR/M is the single biggest driver of that top ranking.
The Number: 7
Bumrah's death economy. The league average at death sits at 10. The distance between those two numbers, 3 runs per over, represents the single largest individual phase advantage in the 2025 IPL. Every team builds their death bowling strategy around getting closer to league average. Bumrah starts 3 runs below it. That's not a marginal advantage. It's a structural floor that resets the equation for every MI innings.
