Former Australian fast bowler Jason Gillespie has suggested that 41-year-old Peter Siddle could be a viable backup option for Australia's T20 World Cup 2026 squad. Gillespie cited Siddle's strong performances in the current Big Bash League, where he is a leading wicket-taker, as evidence of his potential value. He believes Siddle's experience could be beneficial in case of injuries to other fast bowlers, noting that short-term thinking is often effective in T20 cricket.
