Populating the infield against the Yankees were Esteban German at third base, Mike Aviles at shortstop, Alberto Callaspo at second base and Mark Teahen at first base.
Hillman explained that Alex Gordon, in a 0-for-14 slump, needed a day off, and so did 37-year-old Mark Grudzielanek on a hot afternoon after a night game.
Aviles returned after getting two doubles in Friday night's 2-1 victory. He was slotted into Grudzielanek's usual No. 2 spot.
"I want to build on what Mike did yesterday at short and leave him stable where he's at," Hillman said.
He put Callaspo at second because he turns the double play a bit better than German, who filled in at third for Gordon. Teahen started at first base for just the ninth time.
The configuration gave the Royals seven right-handed bats against Yankees left-hander Andy Pettitte.
