Robinson Cano's three-run homer in the slugged the Royals, 7, at Kauffman Stadium.

Cano drove in four total runs while Russell Martin hit a two-run single for the Yankees, who won the opener of this three-game series on Monday by a 7-4 score.

They have taken five of their last six games, and all of those victories have at least one thing in common -- lots of offense. New York has totaled a minimum of six runs, and a combined 40 runs, in those five wins.

The Yankees did their damage Tuesday against Kansas City rookie starter Danny Duffy (3-7), who allowed a career-high eight runs in three-plus innings.

New York starter Ivan Nova (12-4) won his fifth consecutive start and his eighth consecutive decision despite allowing seven runs in 5 1/3 innings.
