Mets club history with Japanese players

Masato Yoshii
Masato Yoshii was the second Japanese pitcher the Mets had in their rotation in 1998. He debuted for the Mets at 33 years old, so his career in the majors topped out at about five years. His 98 season with the Mets, Yoshii went 6-8 with a 3.93 ERA. And though his numbers would balloon a bit in 99 to a 4.40 ERA, his record overall had improved to 12-8.
Yoshii made a few postseason appearances for the Mets. The first in the 1998 NLDS against the Arizona Diamondbacks. He gave up 4 runs that game and posted a 6.75 ERA after five innings. Luckily the Mets would go on to win 8-4, with Turk Wendell getting the W at the end of the night.
The following year Yoshii would make another Game 1 start against Atlanta in the NLCS. Again he had a poor outcome. After four innings, he gave up two runs and posted a 5.40 ERA. The Mets would go on to lose that game 4-2.
