Sponichi is reporting that Baltimore is looking at free agent lefty Hisanori Takahashi, where he would potentially re-join former Yomiuri teammate Koji Uehara.
There's no indication of whether the O's view Takahashi as a starter or reliever, but international scouting director John Stockstill said that if the team does make him an offer, it won't be until January. Baltimore has become active in the Japanese free agent market; last year they were in on Kenshin Kawakami, were the only MLB to look at Ryoji Aikawa, and eventually signed Uehara and Ryohei Tanaka. I could see them picking up Hideki Matsui this offseason as well.
