2014 Outlook: Eaton hasn't had much luck in the injury department during his young career: His 2012 ended prematurely due to a broken hand, and he suffered an elbow injury during spring training that cost him the first 61 regular-season games of 2013. Last year, he never seemed to be his usual self in terms of power and speed, but he'll get a fresh start this year with the Chicago White Sox, presumably taking over as their regular center fielder. It's a cluttered outfield picture, somewhat threatening Eaton's at-bats, and he needs to improve his walk rate to the 11.5 percent mark in his minor league career or 13.6 percent in his brief 2012 stint, but there's a very real chance he could quickly develop into a 10/30 performer who hits atop the lineup. With a strong spring, he'll surely soar up draft boards.
2014 Outlook: De Aza's first full season as a starter rates a success on the heels of a career-high 17 homers, but closer inspection reveals an across-the-board drop in his slash line spurred by a big jump in strikeout rate. This is even more relevant since De Aza may not have the luxury of full-time at-bats to pump up the counting stats. His present role is in a platoon, as Adam Eaton is slated to take over full-time duties in center field. This renders De Aza an intriguing player in AL-only formats, since a trade or an injury to an outfielder will propel him back to regular status. Just don't assume he'll maintain last season's career-best power pace; some give-back should be expected.
2014 Outlook: While last season has to be considered a disappointment for Viciedo, as his homer output tumbled, his doubles and triples went up, so the change in isolated power wasn't as steep as hitting 11 fewer homers might suggest. More worrisome for fantasy purposes is at present, Viciedo could fall into the wrong side of a platoon. This could actually present a buying opportunity in deep leagues, since a trade (Alejandro De Aza) would push Viciedo back to full time. In addition, if Adam Eaton struggles, De Aza could slide back to center, availing more time for Viciedo.
