Red Sox lefty Jon Lester and Rangers reliever Mike Adams have changed agencies, following agent Josh Yates to ACES. Both pitchers had formerly been represented by SFX Baseball. SFX negotiated Lester's then-precedent-setting five-year, $30MM deal three years ago.
It's common for players to follow their agents, and Yates is on his third agency, having been let go by CSMG (now known as Octagon) in '07. An SFX spokesperson said that Yates decided to leave the company and they wish him well. SFX will still collect the fees on Lester's current contract, which runs through 2014 if a club option is exercised. Adams has emerged as one of the game's top setup men and is in line for a multiyear free agent deal after the season.
Also, correcting an earlier tweet from me, the Braves' Randall Delgado remains with SFX.
At first glance, I thought that was a surgery.
