Debutant Shingirai Masakadza took two wickets in the final over to help Zimbabwe to a two-run victory over the West Indies in the first one-day cricket international in Guyana.
The West Indies, chasing 255 for victory, needed 15 off the final over with three wickets in hand but Masakadza bowled Dwayne Smith (4) and Sulieman Benn was caught at midwicket next ball.
With the hosts requiring four off the final ball, Masakadza bowled a yorker to Kemar Roach who could only pick up a single to give Zimbabwe a 1-nil lead in the five-match series.
The West Indies run chase got off to a good start with captain Chris Gayle (57) and Adrian Barath (50) striking up a 99-run opening partnership before four wickets fell for 66 runs.
Shivnarine Chanderpaul steadied the West Indies and put them within sight of victory with a quick-fire 70 before being caught off the bowling of Masakadza, younger brother of Zimbabwe opener Hamilton.
Zimbabwe's Vusi Sibanda fell five runs short of his century in 162-ball innings that included five fours and a six as the visitors reached 254 for five in their 50 overs.
The second ODI is in Guyana on Sunday.
