From FOX Sports' Ken Rosenthal:

The Yankees, in dire need of a setup man, eventually will target the best available late-inning relievers — the Rockies' Huston Street, Diamondbacks' Chad Qualls and Astros' Jose Valverde. In fact, they already have expressed interest in Street, according to major-league sources.

Rosenthal notes that it's unlikely the Rockies would trade Street before the July 31 trade deadline - assuming they move him at all.
