As per ESPN:
KISSIMMEE, Fla. -- Pedro Martinez said he hopes to return to the New York Mets starting rotation before the end of April, despite general manager Omar Minaya's recent statements that the pitcher was expected back by mid-May or early June.
"We will give everyone the surprise of the month, I think, if things keep going well and there are no further delays," Martinez said in an interview with television channel CDN-37 in the Dominican Republic.
Martinez, who was placed on the disabled list after injuring the left hamstring in his first start of the season on April 1, spent a few days in his native Dominican Republic to work with trainer Ángel "Nao" Presinal and to visit his ailing father. Martinez was due back in Port St. Lucie on Wednesday, pending a medical examination of his father.
"I feel a lot better than before. I'm very happy to have spent a few days with Nao and I made the most of my time here working," Martinez said.
Personal trainers such as Presinal are banned from MLB clubhouses after being allegedly linked to the players' use of performance-enhancing drugs. However, major league players are allowed to work with personal trainers outside the ballpark.
"I am surprised with the way I am recovering. It's going much faster than I thought. Everything is moving smoothly," Martinez said. "The Mets know that I'm working and that I will not abandon them. I don't want it to be a long wait like everybody thinks."
Martinez, 36, had surgery in his right shoulder on October 2006, and he did not return to the mound until September 2007. The three-time Cy Young award winner is in his last year of a four-year, $53 million contract signed with the Mets before the 2005 season.
Martinez suggested he may retire at the end of the season if he suffers another arm injury.
"If I end the season healthy I will carry on, but if my arm hurts I will go watch the games on TV in a Dominican bodega," Martinez said.
