Any uncertainty about whether the White Sox were fully engaging in a rebuilding process ended when they made a pair of blockbuster trades on consecutive days at the Winter Meetings. First, they sent five-time All-Star Chris Sale to the Red Sox for second baseman Yoan Moncada (No. 2 on MLBPipeline.com's Top 100 Prospects list), right-hander Michael Kopech (No. 16), outfielder Luis Alexander Basabe and right-hander Victor Diaz. Then they made more headlines by shipping Adam Eaton to the Nationals for right-handers Lucas Giolito (No. 11), Reynaldo Lopez (No. 46) and Dane Dunning.
Those two transactions boosted Chicago's farm system from the bottom 10 in baseball to No. 3 in MLBPipeline's organization talent rankings. The White Sox hadn't been this loaded with young talent at any point in recent memory. The only time they were even close in the last two decades came at the turn of the millennium, when they were setting the stage for a World Series championship in 2005.
• White Sox Top 30 Prospects list
Though overshadowed by the two trades, Chicago's 2016 Draft class could be one of its best in years. Catcher Zack Collins (first round), right-handers Zack Burdi (first) and Alec Hansen (second), outfielders Alex Call (third) and Jameson Fisher (fourth) and left-hander Bernardo Flores (seventh) all made our White Sox Top 30 Prospects list. All told, nine of their 10 best prospects have joined the organization in the last nine months.
Here are the players whose ranks changed the most from the 2016 preseason list to the 2017 preseason list.
