Roenicke said the benching was not a reaction to Friday's errors, but acknowledged that he has been keeping close tabs on the mental state of the second-year shortstop, who has had a tough season on and off the field.
"Sometimes just the mental part of it, he needs to be in there more with energy," Roenicke said. "I told him that when I thought I was seeing a little bit something different in him, that I was going to give him a day off."
After a breakout first half last season that earned him an All-Star selection, Segura scuffled offensively in the second half of last year and has continued to struggle throughout this season. He was batting .232/.270/.316 entering Saturday, though he's maintained his strong defensive presence.
Those on-field struggles were dwarfed by the sudden death of his 9-month-old son on July 12.
Though Segura has recently told Roenicke that he's doing fine, the manager has been careful to continue monitoring his mental state and giving him days off to take some pressure off.
"I talked to him the other day. He said everything is fine," Roenicke said. "He's going to go through some times when he's kind of a little moody, which you understand. It's hard. He's not playing as well as he thinks he should. I told him when I see things, that I will give him a day.
"He's not a guy that is going to come in and let me know. I always go to him. Not necessarily always in my office, but I'll go talk to him in the field and see how he's doing. He's been honest, so I expect him to continue doing that."
Though Segura's second year as a starter has been particularly draining, Roenicke expressed faith that he would be able to fight through his current struggles.
"It is hard to say where he is going to be the next few years. But he's better than what he has shown this year, defensively and offensively," Roenicke said. "I think it has been a tough year for him. They talk about the second year is always tough. Well, we are seeing it with him. Hopefully, he bounces back here and we start seeing the guy that we think is going to be really good at shortstop for a long time."
