I spent a lot of time by his side and now I feel sad, very sad, it is one of the hardest news we have received in recent years. I have no doubt that it fell like a bomb in the whole Cuban sports family.
Back in Matanzas, my players were crying on the bus, with a feeling of great pessimism.
I had to give them the courage to go ahead, and we can do it by giving a better show to the people, playing better baseball and always defending Cuba anywhere in the world.
Similar feelings were expressed by Roger Machado, manager of the Tigers of Ciego de Ávila.
