The Texas Rangers have had internal discussions about trading Joe Nathan, according to sources.
If they do so, it would be with the idea of capitalizing on a thin market for relievers.
Nathan, 38, instantly would become the most attractive closer available.
The Detroit Tigers, Boston Red Sox and Los Angeles Dodgers are clubs looking for relief help.
Joakim Soria, Alexi Ogando or Neftali Feliz could replace Nathan as the team's closer.
