Watch: MLB star Jose Fernandez reunited with grandmother for first time since defecting from Cuba

Jose Fernandez -the NL Rookie of the Year in 2013 - came to the United States by boat as a 15-year-old Cuban refugee in 2008. Along the way, he rescued his mother, who had fallen overboard. However, his beloved grandmother, who Fernandez calls a "baseball freak," was left behind.

"She's the love of my life... my everything," Fernandez said.

The day before winning the Rookie of the Year Award, a shocked Fernandez was reunited with his grandmother in Florida with help from Miami Marlins owner Jeffrey Loria.

As you can see in the video, Fernandez is speechless when his grandmother, Olga, unexpectedly walks into an interview he is conducting with MLB.com.

"Out of nowhere," the pitcher said. "I have no idea how it happened."

According to the Miami Herald, Cuban authorities granted her permission to visit.

Now, she can visit for a few years and see him play in the majors.

"Pretty excited about that," said Fernandez, who has him mother and grandmother's names tattooed on his arm.

Fernandez became an unexpected addition to Miami roster this season, making him the youngest pitcher on a major league team on opening day. The 20-year-old went 12-6 with a 2.19 ERA and 187 strikeouts, becoming the first Cuban to win the NL Rookie of the Year.

"I wasn't planning on being in the big leagues," he said.
