Castro said he was OK, and the ball didn't hit him too hard. After he was plunked, Castro came out of the cage to be examined by assistant trainer Ed Halbur, but the shortstop did go back in against Wood later in the round. When Wood was finished, he went over to Castro to check on the youngster.
"He said, 'I'm sorry,'" Castro said. "It was a fastball in, and it hit me."
The pain must not have lasted long, as Castro lined a ball off the right-field fence off of Carlos Marmol in his next live BP session. Castro also participated in two batting practice sessions off of coaches.
"I'm OK," Castro said. "He didn't hit me too hard."
The shortstop admitted it did hurt a little, but that he's not afraid in the cage.
"I'm never scared about that," Castro said. "I'm never scared. I'm scared if it hits me in the head -- that's not good. ... It happens all the time, practice, games, everywhere."
Cubs manager Dale Sveum didn't expect Castro to miss any activities on Tuesday.
"He's fine," Sveum said. "I wasn't there to witness it, but it sounded a little more scary, but he's fine. He stepped right in and did all his drills after that. It was almost like he didn't get hit."
