Masakadza held off the Bangladesh attack for more than six hours but lacked support at the other end, allowing the tourists to bowl Zimbabwe out for 257 and complete a 143-run victory at Harare Sports Club.
The home side went into the final day with six wickets intact and a slim chance of scoring the 263 runs still required to chase down a target of 401.
