(Update) According to
Buster Olney, "The Yankees' deal with Kevin Millwood is for $1.5 m/ base -- but that's prorated and won't start until May 1 at earliest; could opt out then." He also won't start getting that money until he makes the big league roster.
Aaron Gleeman is reporting that Millwood "can earn an additional $3.5 million in incentives, with $500,000 each for 5, 10, 15, 20, and 25 starts and $1 million for 30 starts."
Brian Cashman continued his valiant attempt to sign every available washed up pitcher in baseball today by signing Kevin Millwood. Here's more from Jon Heyman:
At least it's a minor league deal. Besides that, I have nothing good to say about this signing.
