As Alex Marshall prepares to retire after seven years as the head of the ICC Anti-Corruption Unit, he warns that while elite cricket remains largely safe from corruption, poorly managed local T20 leagues present significant risks. He emphasizes that corruptors target these leagues due to their vulnerabilities and the potential for profit, urging vigilance from cricket administrators. During his tenure, Marshall oversaw notable cases involving players like Shakib Al Hasan and Heath Streak, who faced penalties for failing to report corrupt approaches. He takes pride in the increased trust from players who now more frequently report corrupt approaches to the ACU, a shift attributed to enhanced education and confidentiality measures. Marshall's departure underscores his commitment to maintaining cricket's integrity, particularly in light of the ongoing threats posed by corruptors in lower-tier leagues.
