FRIDAY: Abreu cleared waivers and has been re-signed to a minor league deal, reports Andrew Baggarly of CSNBayArea.com (via Twitter).

SUNDAY, 9:05pm: The release of Abreu brings the competition for the Giants' last backup infield spot down to rookie Ehire Adrianza and non-roster invitee Brandon Hicks, reports Chris Haft of MLB.com. The Giants risk losing Adrianza if he doesn't make the team, as he's out of minor league options.

12:42pm: The Giants have requested release waivers on infielder Tony Abreu, tweets John Shea of the San Francisco Chronicle. The Giants cleared a 40-man roster spot with the move and are only responsible for one-quarter of Abreu's $745K salary, which was agreed to in January to avoid arbitration.

The 29-year-old split the 2013 season between the Giants and Triple-A Fresno. Abreu saw most of his action at second base for San Francisco slashing .268/.301/.442 in 147 plate appearances covering 53 games. Before his June callup, Abreu posted a .338/.366/.523 line at Fresno in 71 plate appearances covering 22 games.

Abreu has a MLB career line of .256/.285/.376 across five seasons with the Dodgers, Diamondbacks, Royals, and Giants.
