Sanspo reports that MLB teams are showing a minimal interested in 32-year-old Hiroyuki Kobayashi. And they have a couple of quotes from an unnamed MLB source. They are as follows:
His name hasn't really come up in the market over here. [Yoshinori] Tateyama got a MLB deal worth US$1M, but he also throws from the side and there aren't too many pitchers like him in the Majors.
Right-handed pitchers, especially the two former Lotte pitchers Yasuhiko Yabuta and Masahide Koabayashi didn't really do much over here and honestly, I think that's turning some [teams] away. If he doesn't mind a start from the minors, I think some teams might be interested... But he doesn't want a minor league deal. If he hasn't received an offer by now, it's probably not going to happen.
I'm guessing [Alan] Nero isn't too stuck on [getting his client] to the Majors at this point. I don't think he'll try to force it.
The article also mentions that teams like the Dodgers, Orioles, and Giants have shown interest, but probably not enough to give him an MLB contract.
