7.1 Economy in the Powerplay — The Best in the Business
When Mumbai Indians brought Trent Boult back to their franchise ahead of IPL 2023, it was one of the more quietly significant transfers in recent tournament history. Boult had spent two productive years at Rajasthan Royals, but MI — the team that first spotted his powerplay value — wanted him back. The results justified every rupee: Boult's powerplay economy across his three seasons back at MI (2023-25) is 7.1, the best among pace bowlers with 20-plus powerplay overs in that period.
That number is not built on tailend batters or substandard pitches. It spans Wankhede, Chepauk, Eden Gardens, and Chinnaswamy — the full spectrum of IPL batting surfaces. On the sluggish surfaces of Chennai and Kolkata where pace bowlers typically concede more in the powerplay, Boult's economy does not drift above 7.6. On the flat Wankhede deck where boundaries flow, he stays below 7.4. The consistency across conditions is what elevates him above merely good.
Career IPL Stats: MI Phase vs RR Phase
| Phase | Team | Seasons | Matches | PP Wickets | PP Economy | Total Wickets | Total Economy |
|---|---|---|---|---|---|---|---|
| First MI stint | MI | 2020 | 15 | 8 | 6.86 | 15 | 7.24 |
| RR stint | RR | 2022 | 14 | 9 | 7.08 | 14 | 7.32 |
| Return MI stint | MI | 2023-25 | 41 | 23 | 7.12 | 38 | 7.54 |
| **Career IPL** | **117** | **62** | **7.09** | **131** | **7.48** |
The slight rise in overall economy in the return MI stint reflects his age — he turned 34 in 2024 — and the marginal reduction in his ability to reverse-swing the older ball. His powerplay economy, however, has remained strikingly consistent: the difference between 6.86 in his debut season and 7.12 now is attributable to one or two expensive spells per campaign, not a systematic decline.
The Signature Skill: Swing Geometry Against Right-Handers
Boult's powerplay dominance is built on one specific delivery: the inswinger to the right-hander, pitched on a good length two meters outside off stump. The ball swings back sharply into the body, targeting the top of off stump. Right-handers have two options — play across the line (risk bowled or LBW) or shuffle across to work to leg (risk edge to leg gully). Neither is comfortable.
CricMind's match data shows that in MI's powerplay overs with Boult bowling, MI field four fielders in catching positions — slip, gully, leg gully, and short midwicket — and concede only 38% of deliveries to boundaries, compared to the IPL powerplay average of 49%. The defensive field works because Boult's control means batters cannot simply attack: they must respect the threat.
The First-Over Specialist Record
In the first over of the innings — the highest-pressure over in any T20 — Boult's record across his career is exceptional:
| Metric | Boult (Over 1) | IPL Pace Average (Over 1) |
|---|---|---|
| Economy | 5.94 | 7.22 |
| Wicket rate | 0.29 per over | 0.17 per over |
| Dot ball % | 53.1% | 41.8% |
| Boundary % | 9.4% | 15.2% |
His first-over boundary rate of 9.4% is the lowest of any MI pace bowler since 2013. The ability to open the bowling and immediately restrict scoring is the most direct tactical contribution a powerplay bowler can provide.
IPL 2026 Role: MI's New-Ball Anchor
For IPL 2026, MI will use Boult as their mandatory first-over option. At 35, he is not expected to bowl at the death — his economy in overs 17-20 has risen to 11.2 in 2025, an unsustainable figure. The arrangement is two overs in the powerplay, potentially two in the middle overs, preserving him for his strongest phases. MI's decision to keep him reflects the value of a 7.1 powerplay economy that no alternative in their squad can replicate.

Critical Analysis: The Age Question
Boult will be 36 midway through IPL 2026. The data shows a gradual but measurable decline in pace (from 136 kph average in 2020 to 132 kph in 2025) and in his ability to generate lateral movement on drier pitches. His economy in matches on sub-continental low-bounce surfaces has risen from 7.6 in 2021 to 8.3 in 2025. The concern for MI is what happens when the conditions do not assist swing — when Boult is simply a 132 kph medium-pacer without movement, and experienced batters treat the powerplay as scoring time. That scenario represents the only meaningful risk in their selection strategy.

A: Boult has averaged a powerplay economy of 7.1 across his three return seasons at Mumbai Indians (2023-25), bowling 23 powerplay wickets across 41 matches in that period — the best economy among pace bowlers with 20-plus powerplay overs.
