A's acquire Frias to complete deal with Mets

OAKLAND -- The A's acquired Minor League right-hander Dawrin Frias from the Mets as the player to be named later in the Aug. 4 trade for Eric O'Flaherty, the club announced on Friday.

Frias, 23, began the season in extended spring training before he was sent to Class A Savannah on May 5. He went 0-2 with an 8.71 ERA in 15 relief appearances with the Sand Gnats before being transferred to Short-Season Class A Brooklyn on July 19.

He compiled a 3.38 ERA in four relief appearances with Brooklyn, yielding three earned runs and striking out 10 batters in eight innings.

The Mets originally signed Frias on Oct. 9, 2008, as a non-drafted free agent out of the Dominican Republic.
