9:28pm: John Perrotto has another article up, saying the Pirates are only interested in Ayala at a "greatly reduced cost," i.e. the "vast majority" of the $700k still owed to him would need to be picked up by the Twins.
8:22am: The Pirates are interested in trading for reliever Luis Ayala, according to Joe Christensen of the Minneapolis Star Tribune. John Perrotto of PiratesReport.com confirms the Pirates' interest in the 31-year-old righty, who was designated for assignment by the Twins on Monday.
Ayala requested a trade weeks ago because he wanted a bigger role in the Twins' bullpen. He makes $1.3MM this year.
