Swisher, ill the last several days with what Girardi called "a real bad head cold," felt the worst he had all week.
"Geno came and saw me," Girardi said. "You start playing in this heat and it even runs you down more, and it's something that's going to linger. He didn't sleep much last night, so I decided to give him a day."
Girardi's original plan was to have Swisher bat second and give Brett Gardner the day off, then do the same with Granderson, who started Friday in center, on Saturday. Now, the days off may have to wait.
"We had talked about giving each one of our lefties a day off in this stretch," Girardi said. "We'll just have to make a decision tomorrow."

Girardi hopes the two hits Alex Rodriguez, who was in a 5-for-40 slump, got after replacing Eric Chavez on Thursday will help get him back to the way he was the first three weeks of the season. "I think a lot of times when you're scuffling as a hitter, no matter what kinds of hits you get, it just gives you a better feeling about yourself," Girardi said. A-Rod went 1-for-4.
Derek Jeter wasn't thrilled to have Thursday off, a day after being removed in the eighth inning with a right hip Girardi said was "grabbing" at the shortstop. Girardi said he had planned to give Jeter Thursday off, anyway. Jeter led off Friday and went 1-for-4.
"Yesterday, he said he was fine and today he's fine, so I put him back out there," Girardi said Friday. "We didn't have an injury, he just felt it was stiff."
