11:23am: ESPN.com's Buster Olney confirms (via Twitter) that Millwood has opted out of his contract with the Yankees.
11:10am: The Yankees have received surprising contributions from veteran starting pitching additions like Bartolo Colon and Freddy Garcia so far this year, but it appears that not all their offseason gambles will pan out. The Yanks expect Kevin Millwood to opt out of his contract and become a free agent today, tweets Jack Curry of the YES Network.
Millwood signed an incentive-heavy minor league deal with the Yankees late in Spring Training that included the option to opt out by today if he hadn't been promoted to the bigs. Curry adds in a second tweet that Millwood's final Triple-A start, in which he lasted just two innings, likely squashed his chances of a call-up.
