The Mariners announced Monday they signed Cuban left-handed pitcher Misael Siverio to a contract, according to MLB.com. The 25-year-old pitcher, who left Cuba in July 2013, played for the Aguilas de Mexicali in the Mexican Pacific League last winter, where he went 3-1 with a 2.45 ERA and 36 strikeouts in six starts.

"This is a proud moment for me, to be able to join the Seattle Mariners, who have several Cubans in the organization that are my compatriots," Siverio said. "I feel very happy because of the way that I have been treated here in Seattle and now the only thing left to do is to do my part, work hard and reach the major leagues."

Siverio will take part in Mariners' mini-camp in mid-to-late February.
