The Orioles, poised to win their first American League East crown since 1997, acquired lefthand-hitting outfielder Alejandro De Aza from the White Sox Saturday night in exchange for righthanders Miguel Chalas and Mark Blackmar.
De Aza fits with Baltimore as a fourth-outfielder option, since the Orioles have a starting unit of Nelson Cruz, Adam Jones and Nick Markakis. Alternately, De Aza could be used in left field while Cruz serves as DH.
Neither Chalas nor Blackmar has ranked among the Orioles’ Top 30 Prospects in their time with the organization.
WHITE SOX ACQUIRE
Miguel Chalas, rhp
Signed out of the Dominican Republic in 2010, Chalas reached Triple-A for his past two appearances, which could have been a showcase for the righthander, who had not previously pitched above high Class A. Chalas throws a four-seamer from 90-93 mph with a max-effort delivery and a fringe breaking ball. He pitched in relief the past two seasons after beginning his career as a starter.
Mark Blackmar, rhp
The son of PGA senior golfer Phil Blackmar, Mark is an athletic, 6-foot-3, 215-pound righthander with a three-pitch mix. His cutter/slider is his best pitch, and he also fills the strike zone with a lively 87-91 mph fastball and a developing changeup. He sliced his walk rate this season to 2.2 per nine innings, but he doesn’t miss many batts with a career strikeout rate of 5.3 per nine innings.
Alejandro De Aza, of
Age: 30 Bats: L
The lefthanded hitter is a career .275 batter against righthanders and adds lefty balance to a team with righthanded thump from Cruz, Jones, Steve Pearce and J.J. Hardy. De Aza is a solid defender in left and center who has shown pop in the past (17 homers in 2013) and speed.
At 30, the Orioles control De Aza for another season. He’s earning $4.25 million in his second year of arbitration.
