"The first half didn't happen like I wanted, but I can't put that in my mind to keep struggling the whole year," Castro said. "It's time to start again."
Cubs manager Joe Maddon didn't have to give Castro a pep talk.
"I know," Castro said.
"Mechanically, you watch him in [batting practice], and he does really well in 'B.P.' and in the game, there's not the same carry over," Maddon said. "I'll defend his work. He's been fabulous with me. Maybe he's not been producing at the level everybody is used to, but I see the guy working and I see the guy caring. That matters to me a lot."
Last year, Castro was batting .276 at the break, and finished at .292, but he missed the last month when he sprained his left ankle on Sept. 2. A three-time All-Star, Castro said it was tough to not have the numbers this year to be considered.
"Like I always say, I want to be at the All-Star Game every year," Castro said. "That's what we prepare for. I'm going to make up for it in the second half -- it'll be fun for me, fun for the team."
