Alejandro De Aza traded to Orioles

BALTIMORE -- The AL East-leading Orioles acquired outfielder Alejandro De Aza and infielder Kelly Johnson in a pair of trades Saturday night, bolstering their bench in the wake of a couple of injuries to key players.

Baltimore sent two minor league right-handers to Chicago for De Aza, who hit .243 with five homers, 31 RBIs and 15 steals in 122 games with the White Sox this year. He made his major league debut with the Marlins in 2007 and is a .268 career hitter with 35 homers and 179 RBIs in seven seasons.

The Orioles got Johnson and minor league infielder Michael Almanzar from Boston in exchange for minor league infielders Jemile Weeks and Ivan De Jesus.

The addition of Johnson provides some infield depth with Manny Machado out for the year with a knee injury and Steve Pearce bothered by an abdominal strain.

Baltimore also completed the moves before Sunday's deadline for postseason eligibility. Players must be with an organization by Aug. 31 to be eligible for the postseason with that team.

The 32-year-old Johnson hit .212 with six homers and 23 RBIs in a combined 87 games for the Yankees and Red Sox. He has played first, second and third base this season, along with left and right field.

Almanzar, 23, was a Rule 5 pick by the Orioles prior to the season.

Weeks, 27, batted .278 in 62 games for Triple-A Norfolk. De Jesus, 27, hit .282 in 113 games for the Tide.

Baltimore parted with Mark Blackmar and Miguel Chalas in the De Aza deal.

Blackmar, 22, is 10-1 with a 3.18 ERA and a .299 opponents' batting average in 26 games (18 starts) with Single-A Fredrick of the Carolina League. He was a 16th-round draft pick by the Orioles in 2011.

Chalas, also 22, is a combined 3-4 with a 4.48 ERA in 30 relief appearances with both Single-A Fredrick and Triple-A Norfolk. He was signed as a free agent by the Orioles in 2010.
