Siraj Has Conceded 9.87 Runs Per Over at Chepauk — 2.4 RPO Worse Than His Career Economy of 7.47
Mohammed Siraj is one of the IPL's most improved fast bowlers. His career economy of 7.47 across 78 IPL matches reflects genuine skill with the new ball and at the death. But against Chennai Super Kings, particularly at Chepauk, Siraj's numbers deteriorate sharply. CricMind breaks down why CSK's batting approach neutralises Siraj's strengths.
Siraj vs CSK — Overall Record
| Metric | Siraj vs CSK | Siraj IPL Career |
|---|---|---|
| Matches | 14 | 78 |
| Overs bowled | 46.3 | 278.2 |
| Wickets | 11 | 72 |
| Economy | 8.92 | 7.47 |
| Average | 37.6 | 28.4 |
| Strike rate | 25.3 | 23.2 |
| Dot ball % | 32.8% | 41.2% |
Siraj's economy against CSK (8.92) is 1.45 runs per over worse than his career rate. More telling is his dot ball percentage — 32.8% against CSK versus 41.2% overall. CSK batters rotate strike against Siraj with unusual ease, preventing him from building dot-ball pressure.
Venue Breakdown — Why Chepauk Is Siraj's Nightmare
| Venue | Overs | Economy | Wickets | Boundary % |
|---|---|---|---|---|
| Chepauk | 16.4 | 9.87 | 3 | 28.4% |
| Chinnaswamy | 48.2 | 6.93 | 18 | 16.2% |
| Wankhede | 22.0 | 7.44 | 8 | 19.7% |
| Eden Gardens | 18.3 | 7.68 | 7 | 18.3% |
Siraj's economy at Chepauk (9.87) is nearly 3 runs per over worse than at his home ground Chinnaswamy (6.93). The boundary percentage tells the story — 28.4% of Siraj's deliveries at Chepauk have been hit for four or six, compared to just 16.2% at Chinnaswamy.
Why CSK Neutralise Siraj
1. Chepauk's slow surface reduces Siraj's pace weapon. Siraj bowls at 140-145 kph — fast enough to trouble batters on bouncy tracks. But Chepauk's low, slow surface reduces effective pace after the pitch. The ball arrives 8-12 kph slower than the release speed suggests, giving CSK's experienced batters an extra 0.04 seconds of reaction time.
2. CSK's left-hand-heavy lineup. CSK have historically batted left-handers in their top four — a tactical choice that exploits Siraj's natural away-swing to right-handers. Against left-handers, Siraj's delivery becomes an in-swinger that left-handers work off their pads. Siraj's economy against left-handers (9.24) is 2.1 RPO worse than against right-handers (7.14).
| Batter Hand | Balls Bowled | Economy | Wickets | Average |
|---|---|---|---|---|
| Right-handed | 482 | 7.14 | 52 | 24.8 |
| Left-handed | 186 | 9.24 | 20 | 38.7 |
3. CSK's experience against pace. CSK's top order has the highest combined T20I/IPL experience against pace bowling of any franchise. Batters like Ruturaj Gaikwad and Devon Conway are exceptional against 140+ kph bowling, particularly when the line strays to leg stump — which Siraj does under pressure.
Phase-by-Phase Analysis vs CSK
| Phase | Overs | Economy | Wickets |
|---|---|---|---|
| Powerplay (1-6) | 22.1 | 7.82 | 6 |
| Middle (7-15) | 14.0 | 9.14 | 3 |
| Death (16-20) | 10.2 | 10.84 | 2 |
Siraj's powerplay bowling against CSK is respectable — 7.82 economy with the new ball, where swing and pace are most effective. But in the middle and death overs, CSK's batters dominate him. The death-over economy of 10.84 against CSK is 2.3 RPO above Siraj's already-elevated death-over career average of 8.54.
Siraj's Counter-Strategies
Siraj has shown tactical evolution in recent seasons:
- Increased use of the slower ball. In IPL 2025, Siraj bowled 22% slower balls — up from 14% in 2023. Against CSK specifically, the slower ball was his most effective delivery, conceding 6.8 RPO compared to 9.4 for his stock delivery.
- Wider lines. Against CSK's left-handers, Siraj has started bowling wider outside off stump rather than targeting the stumps. This reduces scoring opportunities but also reduces wicket-taking chances — a trade-off that keeps the economy manageable.
IPL 2026 Implications for RCB
RCB face CSK twice in the league phase. In both matches, the captaincy decision on when to bowl Siraj is crucial. CricMind's recommendation: bowl Siraj's full 4 overs in the powerplay and early middle overs (overs 1-10). Avoid bowling him at the death against CSK — his death-over economy of 10.84 is a liability.
If one match is at Chepauk, RCB should consider reducing Siraj to 3 overs and using a slower bowler for the fourth.
CricMind Verdict
Siraj is a high-quality IPL fast bowler whose specific strengths — pace, bounce, away-swing to right-handers — are systematically neutralised by CSK's batting lineup and Chepauk's pitch conditions. This is not a flaw in Siraj; it is a matchup disadvantage that RCB must plan around.
Prediction for IPL 2026: Siraj will concede 35+ runs in at least one of the two CSK matches, but will take 2+ powerplay wickets across the two games.
