August’s mega-deal between the Boston Red Sox and Los Angeles Dodgers is officially complete, as the Red Sox announced Thursday that they have acquired pitcher Rubby De La Rosa and outfielder Jerry Sands from the Dodgers as the “players to be named later” from that trade.

The original terms of said deal, which was consummated on August 25, saw Boston send Josh Beckett, Carl Crawford, Adrian Gonzalez, and Nick Punto to Los Angeles in exchange for James Loney, Ivan DeJesus Jr., top pitching prospect Allen Webster, and two players to be named later.

De La Rosa and Sands were already known to be the players to be named later in that deal, but because it happened after the August 1 non-waiver trade deadline, the two sides had to wait until the end of the season to make it official.

Sands, 25, spent most of 2012 at Triple-A Albuquerque, hitting .296 with 26 home runs, 107 RBI, and 84 runs scored in 119 games. He also played in nine games for Los Angeles, hitting .174 with one RBI, and did post a .253-4-26 line in 61 games for the Dodgers back in 2011.

De La Rosa, meanwhile, was, along with Webster, considered to be one of the top three pitching prospects in the Dodgers system, and was 4-5 with a 3.71 ERA in 13 games (10 starts) for the Dodgers in 2011. However, he underwent Tommy John surgery last August and missed most of 2012, making just a handful of appearances at the Minor League level and one for the Dodgers back in late-August.

In a related move, one made to make room on the 40-man roster for De La Rosa and Sands, the Red Sox designated catcher Guillermo Quiroz for assignment.

Quiroz, 30, spent most of 2012 with Seattle’s Triple-A affiliate in Tacoma – where he hit .278 with 15 home runs in 89 games – and was purchased by the Red Sox in September to serve as Major League depth. The 30-year-old backstop has played parts of eight major league seasons with Boston, Seattle, Baltimore, Texas, and Toronto, and is a career .206 hitter in 257 at-bats.
