"He's about the only guy who hasn't had a day off," Girardi said. "You get a little bit concerned, so you take the initiative, 'You know what? I'm going to give you a day off.'"
The 30-year-old Gardner has not taken a full day off since April 27, a span of 60 games. The last time he did not start was May 22, a span of 39 straight starts.
"A lot of times, when you have a guy who's 30 or 31 -- I've been on some teams where that's one of the older guys," Girardi said. "But on this team, he happens to be a young guy, and I don't remember the last time Gardy's had a day off.
"I think one of the things we deal with here is age. We don't have 25-, 26-year-olds running out there every day. You get your speed guys, and they're on the bases a lot. They're running a lot. Their legs get sore, and you worry about them physically."
Alfonso Soriano took Gardner's spot in left on Saturday afternoon.
