"I will do what the manager asks me to do. If he wants me to be a starter, I'll do it," Acosta said.
Acosta finished the 2012 season strong, compiling a 1.78 ERA in 26 appearances after the All-Star break. The right-hander joined the Panama National Team looking to continue to perform at his best.
"All of us here will give 100 percent for Panama and I am here to contribute to that," said Acosta, who is looking for a spot in the pitching staff next to his brother Alberto.
Acosta, 31, didn't see much action in the 2006 tournament, and due to personal reasons, he didn't participate in 2009. Now he is looking to help Panama qualify to compete against the world's elite.
"I'm really proud to represent my country and we want to give the fans what they deserve."
Even though the Mets fell out of contention in 2012, Acosta was glad to be one of the team's bright points down the stretch.
"That is part of baseball," Acosta said. "It's full of ups and downs, but I'm happy that I was able to end the season the way I did."
