2011-2012 Cuban National League
The 2011-2012 Cuban National League was the 51st Cuban Serie Nacional campaign. The league saw the first change in the teams since it went to 16 entries in 1992-1993. The La Habana Province was split in two, replaced by Mayabeque Province and Artemisa Province. As a result, the three-time champion La Habana team was replaced by corresponding Mayabeque and Artemisa teams. Rumors originally had been that the Metropolitanos team would be removed, leaving Cuba with one team per province, but the league instead went to an awkward 17-team format. The two expansion teams promptly posted the league's two worst records. There were also many managerial changes, with only six of the 16 managers from 2010-2011 returning after a couple years of stability.
The Mizuno ball 200 was used during the season, while the league continued to implement the controversial "Schiller rule" regarding extra innings play. The pitcher's mound was raised to a height of 15 inches, five more than what is used in Major League Baseball. 
The season opened on November 27th, with a rematch of the 2010-2011 finalists. This time, Ciego de Ávila beat Pinar del Rio, 8-4. Vladimir García beat 2010-2011 finals MVP Yosvani Torres while Yoelvis Fiss went 4 for 4 with a 2-run homer.
A major record was also broken in March. On March 6th, 43-year-old Enrique Esteban Díaz (already Cuba's all-time steal leader) broke up a no-hitter by Reinier Verano with two outs in the 6th inning to tie Antonio Pacheco with 2,356 career hits. He topped Pacheco a day later with a single off Julio Martinez.
On March 13th, the Schiller Rule took effect in a no-hitter for the first time. 20-year-old Raimar Navarro entered the game with a 12-23 career record for Holguín but overcame eight walks to toss nine no-hit shutout innings. He was matched zero for zero by Frank Madan of Camagüey. Madan finally allowed a run in the 10th thanks to the Schiller Rule. In the bottom of the 10th, Pablo Fernández finished the no-hitter, the third combined no-no in Cuban annals and the first since 1979.
On April 3, Alfredo Despaigne took Ian Rendón deep for his 34th home run of the year, reclaiming the home run record he had set three years earlier but which had been broken in 2010-2011 by Abreu and Yoenis Céspedes. Abreu later caught up to him at 35 but Despaigne hit an inside-the-park shot (his only such homer this season) off Alesky Perera on the final day of the season to finish with the record.
The finals began on May 20 at the historic Estadio Latinoamericano. In a pitcher's duel, both Vladimir García and Odrisamer Despaigne tossed six shutout innings in front of 55,415 fans. In the 7th, Ciego de Ávila loaded the bases against Despaigne. A wild pitch and a passed ball by Lisban Correa scored Yoelvis Fiss and Isaac Martínez. Raúl González then drove in Lisdey Díaz for a 3-0 lead. García also allowed a run in the bottom of the 7th. In the bottom of the 9th, Alexander Malleta scored on a hit by Yasmani Tomas for the Industriales. It was only the third hit allowed by García. That brought up Carlos Tabares, a 38-year-old former Olympian. He was no match for one of Cuba's top hurlers, as Tabares was retired to end it.
Game 2 was delayed a day due to rain. On May 22, Ciego de Ávila romped to a 8-3 win. Starters Ian Rendón (Industriales) and Osmar Carrero (Ciego de Ávila) both struggled, getting knocked out in the 5th, but Yander Guevara tossed 4 1/3 shutout innings of one-hit, no-walk relief for the win while the Industriales bullpen was spotty. DH Isaac Martínez led a balanced attack for the victors, going 2 for 3 with 3 RBI.
With game 3 on May 27, action moved to Estadio José Ramón Cepero but the home team lost for the third straight game. Both game 1 starters returned and again did well. Vladimir García carried a 3-1 lead into the 9th but faded and allowed two runs. In the 10th, against reliever Guevara, the Industriales scored the winner on an error by catcher Lisdey Díaz. The Industriales were led by three players who had 3-for-5 days: 1B Malleta, 2B Juan Torriente and 3B Rudy Reyes.
A day later, Ciego de Ávila pulled off the second rout by a 10-2 margin. Rusney Castillo went 3 for 5 with two home runs and four RBI and got plenty of help, as Yorelvis Charles was 4 for 5 with two doubles and 3 RBI and both Raúl González and Isaac Martínez went deep. Industriales starter Frank Monthiet and five relievers all failed to stop the Tigres, while Osmar Carrero pitched a fine game for the win.
On May 29, Ciego de Ávila wrapped up its first title, beating the 12-time-champion Industriales. This one was a classic finale, going 11 innings before it was settled with a 4-3 score. The Tigres opened with a first-inning run as Fiss doubled in Castillo while facing Industriales starter Antonio Romero. In the second, a two-run homer by Yoandri Urgellés off Guevara put the Industriales ahead. Ciego de Ávila reclaimed the lead in the bottom of the third when Fiss doubled in Ricardo Bordón and Raúl González. From there, Romero and Guevara traded goose eggs from the 4th through the 6th. In the 7th, Urgellés singled and came around on a sacrifice fly by pinch-hitter Irakli Chirino to tie the game at 3. Neither team scored again until the 11th. Yorbis Borroto reached against Industriales reliever Julio Montesinos (who had entered in the 9th, replacing Romero) and was advanced by Díaz. Bordón then came through with his 3rd hit of the game, the winning single, to give the team their first championship after 35 seasons of play. The decision went to Lázaro Santana Jr., who had gotten the last two outs in the top of the 11th after Guevara was finally yanked.
