The team has extended minor-league deals with spring training invites to former Los Angeles Dodgers lefty Will Ohman and Japanese import Hisanori Takahashi. Barring acceptance from one or both, or possibly from a right-handed reliever, the spring roster is set.
The Mets are also focused on getting another left-handed pitcher for the bullpen, which is primarily why they have shown interest in Hisanori Takahashi, who pitched for the Yomiuri Giants. Takahashi was a starter in Japan, but he could work out of the bullpen and evolve into an emergency starter if the need arose.
Takahashi and his agent have gone on record a number of times that they are looking for a MLB deal and that they aren't in any rush to sign a deal right away. Takahashi is looking for a major-league deal and a serious chance to start.
There are plans for Takahashi to fly to the US on the 31st to continue his training over there. He's also planning on starting a throwing program beginning February 1st.
