"I'd rather [give him time off] and be proactive and give him rest," Maddon said Monday. "It's his All-Star break."
Zobrist, 35, said he isn't feeling any aches or pains, just a little road weary. The Cubs played 24 straight games prior to the All-Star break.
"[Maddon] asked me the day we came back, 'How are you feeling?' and I said, 'I don't feel rested,'" Zobrist said. "He said, 'I'm going to give you a day off coming up here soon' and he picked Sunday. I assumed it'd be Sunday and I'd be playing today.
"I think it'll be good to stay off my feet a little bit and try to get caught up. I didn't feel like the break helped me get caught up as much as I wanted to. These couple days and an off-day Thursday, and by then I'll be feeling great."
It helps that Zobrist's sub, Javier Baez, is playing well. Baez has scored or driven in a run in 14 of his last 17 games with an at-bat, and he was batting .346 in his last 15 games entering play Monday. Baez, 23, spent the All-Star break vacationing in Mexico.
"You don't need as much [time off] when you're younger and you have more energy and bounce back quicker," Zobrist said, "but after that 24-game stretch, when we didn't have that much down time, it's taken me longer to bounce back than I realized.
"It's a good mental break to be a fan and really cheer your teammates on instead of being out there every day."
