The Yankees promoted Lombard from High-A Hudson Valley to Double-A Somerset on Sunday, Jeff Passan of ESPN.com reports.
Lombard earned the bump up to Double-A after slashing .329/.495/.488 with one home run, 11 stolen bases and a 21.9 percent walk rate over 111 plate appearances for Hudson Valley. The 19-year-old shortstop is considered to be among the top prospects in the Yankees organization, with his advanced plate approach being his most appealing trait.
