"I was joking with him the other day, I said, 'You know, you never ask for a day off,'" McClendon said. "He said, 'Oh, is that what I'm supposed to do?' I said, 'It's too late now.'"
Seager is hitting .292 with 18 homers and 70 RBIs during the 105-game uninterrupted streak.
"He's young, he's strong -- real strong legs," McClendon said. "He's just one of those guys … wind them up and they go, and they get better. Ideally that's not what I'd like to do, but at this point it is what it is. We'll work on it again next year."
Last season, Seager hit .183 in the final two months of the season.
"He probably, from a mental standpoint, is much more prepared," McClendon said of the stretch run this year.
