The Yokohama Bay Stars are taking a look at Taiwanese left-handed pitcher Yi-Zheng Wang (王溢正). Wang is currently taking part in the team's Fall camp. If he impresses the Bay Stars enough, they might try to sign him to an offer some time this month.
As far as what I could find on Wang... He was apparently a starter for the minor league La New Bears of the CPBL.
His numbers from this past season:
7 G, 1-1, 27.1 IP, 21 BB/HBP, 15 SO, 18 ER, 5.93 ERA
