Via Ken Rosenthal:
Yankees Class AAA right-hander Russ Ortiz has exercised his right to become a free agent, according to his agent, John Boggs.
Ortiz, 35, had the right to become a free agent if the Yankees did not promote him to the majors after three starts.
He made his third start for Scranton/Wilkes-Barre on Sunday, allowing three runs in four innings after pitching 13 scoreless innings in his previous two starts. Ortiz was 2-1 with a 1.59 ERA for SWB after going 3-6 with a 5.57 ERA for the Astros, who released him on July 30.
The Yankees, unable to currently offer Ortiz a spot on their major-league roster, asked him to remain in their organization. But Ortiz wants to be part of a contender and return to the postseason, Boggs said.
