Tazawa? He has excellent stats. His ERA is like 1.00 when he is ask to preserve a lead or hold a tie game. His struggles seems to be at garbage times when the team is leading 5 or trailing 5.
This is a huge lost for the Yankees. They need to take Lee/Hammels contract from the Phillies to fill the void in their rotation, they're one of the few teams that can do such.
