Pitcher Hiroki Kuroda, who is now completing his sixth big league season following 11 years in Japan, told Kyodo News recently that his future after this season is up in the air — just as it has been since 2012.

"For me, each and every year has to be its own challenge," said the 39-year-old Kuroda, who is completing his third one-year deal with the Yankees. "I want to go through the year pitching every game so that I have no regrets. And should I feel I've reached my limit, then that is the easiest way to go out. I think that will make it a decision (to quit) for me."

In an exclusive interview with Kyodo at Yankee Stadium in New York, Kuroda said he would not rule out a return to pitch in Japan, where he starred for the Central League's Hiroshima Carp.
