Osvaldo Duvergel pitched in Cuba and for the Cuban national team.
Duvergel debuted in the Cuban Serie Nacional in 1980-1981.  He was 8-8 with a save and a 3.61 ERA for Guantánamo in 1985-1986, leading the league with 24 games pitched (one ahead of Pedro Palma) and tied Claudelino Jiménez and Félix Núñez for the lead with seven batters plunked. He tied for 8th in wins. He was 13-2 for the Serranos when they won the 1987 Series Selectivas. He tied Luis Tissert for the win lead and led in winning percentage. 
In the 1987-1988 Serie Nacional, he was 9-8 with a 5.20 ERA. He tied José Luis Alemán for the most wins in the eastern division though he also allowed the most hits (111). He had similar numbers (9-6, 3 Sv, 5.22) in 1988-1989, again tying Alemán for the most wins in the east while again surrendering the most hits (131). His ten complete games led the Series Selectivas in 1989. His ten wins tied Lázaro Valle, Reinaldo Santana and René Arocha for the lead. In the 1989 Intercontinental Cup, he had no decisions and a 0.00 ERA for the champion Cuban squad. 
Osvaldo fell to 2-6, 6.74 in 1989-1990 then had a 3-5, 4.80 record in 1990-1991. Despite some unimpressive seasons, he still made Cuba's team that summer. He was 1-0 with a 4.00 ERA in the 1991 Intercontinental Cup.  He came up big in the finale. Japan knocked out Omar Ajete in the 4th when Duvergel came in; Japan got three runs against Ajete while Cuba had yet to score. Their run of Gold Medals in international tournaments dating back to 1982 appeared in danger. Duvergel held Japan to one run in the next six, scattering eight hits and three walks before Wilson Lopez relieved, while Cuba tied it in the bottom of the 9th (Japan's run off Duvergel came in the 10th). Cuba won in the bottom of the tenth to seal the Gold.  Duvergel was 1-0 with a 4.50 ERA when Cuba won the 1991 Pan American Games. 
The Guantánamo native rebounded to 5-6, 3.43 in 1991-1992 but dropped to 5-11, 4.25 in 1992-1993. He tied Liván Angarica for second in the league in losses, three behind Gervasio Miguel. He was 3-8 with a 5.11 ERA in 1993-1994, tying for 8th in losses. He improved to 3.97 in 1994-1995 but had a 5-9 record (Guantanama's other pitchers were 11-36, so they had little support). He tied Norge Batista, Evacio Negrín, Walberto Quesada and Alexis Riera for the most losses. He was 5-5 with a 4.43 ERA in 1995-1996.
He was 129-134 with eight saves and a 5.03 ERA in 394 career games. He was 45th in games pitched (as of 3/8/2022), 38th in starts (269, between Julio Romero and Yosvany Fonseca), 14th in complete games (135, between Ciro Silvino Licea and José Darcourt), tied for 42nd in wins (with Teófilo Pérez and Darcourt), 17th in losses, 34th in IP (2,026 1/3, between Rolando Arrojo and Luis Miguel Rodríguez) and tied José Angel García for 31st in walks (717).  His winning percentage was hurt by playing for weak teams and his ERA was higher due to the aluminum bat era.
