The Rays' policy has always been to listen to anybody who wants to discuss a trade. Normally all players are available, so any deals come down to whether Tampa Bay thinks it is improving its club.
Given the lack of available starting pitching around the league, the Rays hold the upper hand for teams hoping to procure a starter who might push them over the top. Tampa Bay could afford to trade one or even two starters if the yield is right.
Any trades the Rays make would need to bring a Major Leaguer or another organization's top prospect/prospects in return.
