(Updates market action after 10-year auction)
NEW YORK, July 13 U.S. Treasuries prices trimmed losses in early afternoon trading on Wednesday, prompted by Fitch's downgrade of Greece and solid demand for $21 billion in 10-year note supply.
Benchmark 10-year Treasury notes US10YT=RR last traded down 9/32 in price with a yield of 2.91 percent.
They had traded down as much as 19/32 lower for a yield of 2.95 percent prior to the Greece downgrade and the 10-year note reopening. (Reporting by Richard Leong; Editing by James Dalgleish)
