"There's not a message," Gibson asked when asked if he was trying to send one with the lineup. "Last night, you could see guys are overly frustrated. We're in the middle of a road trip, and other guys are preparing as well, so we gave a couple of guys a day off today. And get some of the guys in there, get them an opportunity. There will be some other guys getting some days off in the upcoming days as well."
Parra, a Gold Glove defender in right, had played in 83 of the team's 86 games entering Thursday and was mired in a slump at the plate with just one hit in his past 21 at-bats.
Prado, meanwhile, is just 4-for-20 on the trip and has performed below expectations.
"I think he's frustrated, yeah," Gibson said of Prado. "He's been pressing hard. Everybody wants to do good. That was one of our poorer games that we played last year, I thought. We'll get him a day off today and he'll be back in there for the Atlanta series. These guys care a lot. They try to overthink things. They don't mean to, but it happens. I'm just trying to give them a break, give the other guys an opportunity."
