Yoshihisa Hirano said during his introductory news conference on Monday that he wants to become the closer for the Arizona Diamondbacks.

The 33-year-old right-hander agreed to a two-year, $6 million deal in December.

"The D-backs were the first team that made me an offer," Hirano said through an interpreter. "When me and my family came over to visit Arizona in December, general manager Mike Hazen and field manager Torey Lovullo were there, greeted me and my family very warmly and made my family feel like home now already, and that was the reason I chose the Diamondbacks."

Hirano pitched out of the bullpen the past eight seasons in Japan, with a league-leading 41 saves in 2014. Since 2010, he appeared in 476 games, going 30-33 with 156 saves and a 2.30 ERA with 564 strikeouts, an average of 9.83 strikeouts per nine innings.

"I've been a closer in Japan, but hopefully that will be my goal," he said, "but I'm willing to pitch in any situation that Torey tells me to."
