The Mets have let their flexible pitcher Hisanori Takahashi enter free agency after the two sides failed to reach an agreement on a new deal.The Mets and Takahashi extended their deadline to make an extension deal until midnight tonight. Takahashi was seeking a three-year $12-15MM contract, and the Mets were hoping for one lone year, and perhaps an option for a second.Takahashi posted a 3.61 ERA in 122 innings as both a starter and reliever in 2010, while racking up 10 wins and 8 saves in the process.On a personal note, if any 35 year old middle-reliever believes he's going to get a 3-year deal worth $4-5MM annually, it's just not going to happen. Takahashi will henceforth be known as "Bakahashi."  (just kidding! good luck Hisanori, where ever you end up!
