I think Lockie Ferguson might be done at international level
He's had 4 poor franchise tournaments in a row:
ILT20 2025-26: average 28, economy 8.00
IPL 2026: average 141, economy 12.81
MLC 2026: average 165, economy 11.00
The Hundred 2026: average 24.22, economy 9.08
This is in addition to a poor T20 World Cup. Outside that tournament, he's played 4 matches for NZ in the last 2 years. He is 35, which is not really an age at which fast bowlers usually tend to improve. He'll be 37 by the next T20 World Cup.
Personally I'd be looking elsewhere for the upcoming T20s against India, even if he's fit and available.
