According to multiple major media sources, including the very reliable Brian Costa at the Star Ledger, the Mets are near a deal with the veteran Japanese lefty Hisanori Takahashi.
Takahashi has pitched for the Yomiuri Giants for a decade, and while he has largely been a starter, with some success, he is projected to be a lefty out of the pen to complement Feliciano.
While this name may not excite everyone, he was quite good two of the last three years, and apparently the Mets won a bidding contest (war might be a bit too much for this case!) with the Red Sox and Dodgers among a few others.
This scouting report is from the NY Times:
He is listed at 5 feet 10 inches and 172 pounds and is said to throw 86 to 90 miles an hour. He has five pitches, all of which he uses at various points in the count to keep hitters off balance, and he does not shy away from challenging hitters.
Last season he was 10-6 with a 2.94 earned run average and struck out 126 batters and walked 36 in 144 innings. His best season was 2007, when he went 14-4 with a 2.75 E.R.A., made the Central League All-Star team and was named to the Best Nine, meaning he was considered the best pitcher in that league.
