Marsh's Fitness Woes Plague Australia Ahead of Zimbabwe T20 WC Clash

• Mitchell Marsh's fitness is a major concern for Australia due to internal testicular bleeding, requiring significant rest.
• Steve Smith has joined the squad as cover for Marsh, who missed Australia's 67-run victory over Ireland.
• Australia aims to improve their batting performance, especially from Travis Head and Glenn Maxwell, against Zimbabwe.
• Zimbabwe, with pacers like Brad Evans and Blessing Muzarabani, and all-rounder Sikandar Raza, poses a potential threat.
• Brendan Taylor is nursing a niggle, potentially opening a spot for Ryan Burl or veteran spinner Graeme Cremer.
