The three-time Cy Young Award winner threw a simulated game on Tuesday in the Dominican Republic and is on track to start for the country's World Baseball Classic squad in the team's first exhibition game on March 3, according to the Dominican newspaper Hoy.
According to the report, Martinez's velocity ranged from 88-92 mph in the 43-pitch outing at Baseball City, a sports complex near Boca Chica.
"Pedro was working really well, he threw the ball like normal and he showed good physical condition," Dominican team staff member Rafael Mateo told the paper.
The report also stated that Martinez, 37, plans to throw Friday before traveling to Florida on Sunday to join the Dominican Republic squad. Two days later, he will pitch against the Marlins at Roger Dean Stadium in Jupiter.
"Pedro finds himself in good physical condition, and it's evident that he has been working hard in his preparation for the upcoming season," Mateo told Hoy.
The Dodgers, Pirates and Indians are interested in signing Martinez, but the right-hander has not received an official offer, according to the newspaper.
