After acquiring Marlon Byrd at the July trade deadline, the San Francisco Giants have added to their outfield depth again, acquiring Alejandro De Aza from the Boston Red Sox at the August trade deadline, according to FOX Sports' Ken Rosenthal:

The Giants will be De Aza's third team of 2015, as he started the season with Baltimore before being traded to Boston on June 3. He hit .214/.277/.359 with the Orioles and .292/.347/.484 with the Red Sox, giving him a .755 OPS on the season.

This is the second-straight season that De Aza has been involved in a waiver trade. The White Sox traded him to the Orioles on August 30 last season. The Giants will be hoping he can replicate the .293/.341/.537 line he had for Baltimore down the stretch in 2014. It will also be De Aza's first return to the National League since being waived by the Marlins after the 2009 season.

In exchange for De Aza, the Red Sox will be receiving minor league reliever Luis Ysla, according to The San Francisco Chronicle's Henry Schulman:

Should be Luis YSLA for De Aza. #sfgiants.

Ysla is a 23-year-old who spent this season at High-A San Jose, posting a 6.21 ERA and 1.88 WHIP in 79⅔ innings, walking 41 and striking out 95.

With both Angel Pagan and Hunter Pence on the disabled list, De Aza will join a Giants outfield that includes Byrd, Nori Aoki, Gregor Blanco and Justin Maxwell. Utility man Juan Perez has also started three games in the outfield recently.

De Aza has played plenty of both corner outfield spots this season, and will likely fit in as the left-handed side of a platoon with Byrd in right field until Pence returns from his oblique injury. De Aza has hit .282/.337/.467 with all seven of his home runs against right-handed pitching this season.
