It's still relatively early on in Spring Training, but the White Sox have already begun getting calls on outfielders Alejandro De Aza and Dayan Viciedo, according to Jon Heyman of CBS Sports (on Twitter). The two are battling for the everyday job in left field, as it 2013 trade acquisitions Adam Eaton and Avisail Garcia are likely to man center field and right field, respectively.
De Aza is the more established player of the two but also comes with less team control. Set to turn 30 in early April, De Aza has batted .279/.343/.420 in 357 games with the White Sox since being claimed off waivers from the Marlins in 2009. The lefty swinger belted a career-high 17 homers last season and has stolen 46 bases over the past two seasons. Ultimate Zone Rating pegs him as an average defender in the outfield, though Defensive Runs Saved feels he's somewhat below average. He has extensive experience in center field and also played 426 innings in left field for the Sox last season. De Aza is under team control for two more seasons and will earn $4.25MM in 2014.
Viciedo is the younger and more powerful of the two, but comes with question marks about his defense and on-base skills. Viciedo, who turns 25 on Monday, mashed 25 homers in his first full season with the Sox in 2012, posting a .255/.300/.444 triple-slash line. However, he wasn't able to match that power level in 2013, as he hit just 14 homers with a .265/.304/.426 slash line. UZR/150 pegs him at -5.5 over his career in left field, while DRS has him at -3. Both metrics agree that his glove worsened in 2013. As a Super Two player, he'll earn $2.8MM in 2014 and is controllable through the 2017 season.
De Aza would seem to be a natural fit with the Tigers, who recently learned that they'll be without Andy Dirks for roughly three months due to back surgery. His left-handed bat would pair well with Rajai Davis to form a left field platoon, which was supposed to be the role filled by Dirks. With an extra year of team control, he could potentially fill Torii Hunter's spot in 2015 if Hunter signs elsewhere and the Tigers don't find a suitable replacement on the free agent or trade market. Of course, this is all purely speculation on my part, and the White Sox and Tigers may prefer not to swing a trade within their own division. Other teams that could use an upgrade in the outfield include the Orioles, Mariners and Pirates, to name a few.
